SOAP Notes Assessment Section: What to Write & Examples
The assessment in SOAP notes is where clinical reasoning happens. Learn exactly what to include in your SOAP clinical assessment, see real examples across specialties, and avoid the most common documentation mistakes.
What Is the Assessment Section in SOAP Notes?
The assessment in SOAP notes is the "A" in the SOAP acronym and represents the clinician's clinical reasoning, diagnostic conclusions, and professional interpretation of the patient encounter. It is the section where you synthesize everything gathered in the Subjective and Objective sections into a cohesive clinical picture.
Think of the assessment as the "thinking" section of your note. While the Subjective section captures what the patient tells you and the Objective section records what you observe and measure, the SOAP clinical assessment is where you interpret that data. It answers the fundamental clinical question: "Based on everything I know about this patient, what do I think is going on?"
According to CMS documentation guidelines, the assessment must demonstrate the medical necessity of services rendered and support the level of evaluation and management (E/M) coding billed. A well-written assessment bridges the gap between raw clinical data and your treatment decisions, creating a clear chain of reasoning that other providers, auditors, and payers can follow.
How the Assessment Connects S + O
Subjective
Patient reports chest pain radiating to left arm, onset 2 hours ago, rated 7/10
Objective
BP 158/92, HR 98, ECG shows ST elevation in leads II, III, aVF. Troponin elevated at 0.8 ng/mL
Assessment
Acute inferior STEMI (I21.19). Presentation consistent with acute coronary syndrome given chest pain pattern, ECG changes, and elevated troponin.
The assessment is arguably the most intellectually demanding part of the SOAP note. It requires clinical knowledge, pattern recognition, and the ability to weigh competing diagnoses. A strong assessment soap note section demonstrates not just what you concluded, but why you reached that conclusion. This is what separates documentation that merely records from documentation that communicates clinical thinking.
What to Include in a SOAP Note Assessment
A complete SOAP notes assessment includes several key elements that demonstrate your clinical reasoning and support accurate coding and billing. Not every assessment will include all elements below — the complexity depends on the encounter type, patient acuity, and number of active problems.
Assessment Section Checklist
Primary Diagnosis / Clinical Impression with ICD-10 Code
State the most likely diagnosis or clinical impression first. Always include the corresponding ICD-10 code for specificity and billing accuracy. Example: "Type 2 diabetes mellitus with diabetic chronic kidney disease, stage 3 (E11.22)"
Differential Diagnoses (Rule-Out List)
List alternative diagnoses being considered, with reasoning for or against each. This demonstrates clinical thoroughness and protects against diagnostic anchoring. Example: "R/O pulmonary embolism — Wells score 2 (low probability), but given recent immobilization, D-dimer obtained."
Clinical Reasoning Connecting S + O to Diagnosis
Explicitly state how the subjective complaints and objective findings support your diagnosis. This is the core of the assessment — the interpretive bridge between data and conclusion. Example: "Gradual onset dyspnea with bilateral crackles, elevated BNP (1,240 pg/mL), and cardiomegaly on CXR are consistent with acute decompensated heart failure."
Disease Severity / Stage
Indicate the severity or stage of the condition when applicable. This guides treatment intensity and supports medical decision-making complexity for billing. Example: "COPD, severe (GOLD Stage III), with FEV1 35% predicted."
Prognosis
Include a brief prognosis statement, especially for chronic conditions, rehabilitation encounters, or when it impacts treatment decisions. Example: "Prognosis good for functional recovery with consistent PT participation over 6-8 weeks."
Response to Current Treatment (Follow-Up Visits)
For established patients, document whether current therapy is working. This informs treatment modifications in the Plan section. Example: "HTN poorly controlled on current regimen of lisinopril 20 mg daily — average home BP readings 152/94 over past 2 weeks."
Risk Stratification
When relevant, include risk scores or stratification to guide management intensity. Example: "HEART score 6 (high risk) — warrants admission and cardiology consultation."
How to Write an Effective SOAP Note Assessment
Writing a strong assessment in SOAP notes is a skill that improves with practice. Follow this step-by-step approach to produce assessments that are clinically sound, well-organized, and audit-ready. The National Library of Medicine emphasizes that clinical documentation should reflect the complexity of medical decision-making, and the assessment is where that complexity is most visible.
Start with the Primary Diagnosis
Lead with your most important clinical conclusion. State the diagnosis clearly and include the ICD-10 code. If you are working up an undifferentiated complaint, state the working diagnosis or chief concern. For patients with multiple problems, list the most acute or clinically significant problem first.
Example: "1. Acute exacerbation of COPD (J44.1) — presenting with increased dyspnea, productive cough with purulent sputum, and decreased air entry bilaterally."
Support with Evidence from S and O
Reference specific findings from the Subjective and Objective sections that led to your conclusion. Do not simply repeat the data — instead, explain how it supports your diagnosis. This is the interpretive step that distinguishes a good assessment from data regurgitation.
Example: "Diagnosis supported by 3-day history of worsening dyspnea (S), SpO2 88% on room air, bilateral expiratory wheezes, and CXR showing hyperinflation without infiltrate (O)."
List Differentials with Reasoning For/Against
Demonstrate your clinical thinking by listing alternative diagnoses and briefly explaining why they are less likely or still being considered. This shows thoroughness and protects against missed diagnoses. Even if you are confident in your primary diagnosis, mentioning differentials you considered and ruled out adds depth to your documentation.
Example: "Differential includes pneumonia (less likely given clear CXR, no fever), CHF exacerbation (no peripheral edema, BNP within normal limits), and pulmonary embolism (low probability, Wells score 1)."
Note Relevant ICD-10 Codes
Include ICD-10 codes for every diagnosis or problem addressed. Use the most specific code available — avoid unspecified codes when clinical information supports greater specificity. This supports accurate billing and reduces claim denials.
Example: "E11.65 — Type 2 diabetes mellitus with hyperglycemia" rather than the less specific "E11.9 — Type 2 diabetes mellitus without complications."
Include Severity and Prognosis
Describe the severity of each condition and, when appropriate, the expected clinical trajectory. This helps other providers understand the urgency of the situation and justifies the level of care provided.
Example: "Moderate severity based on respiratory distress at rest and hypoxemia requiring supplemental O2. Expected to improve with bronchodilator therapy and systemic corticosteroids over 3-5 days."
Address All Problems Identified
If the patient has multiple active problems, each one should be addressed in the assessment. Use a numbered problem list format for clarity. This ensures nothing is overlooked and supports comprehensive care documentation.
Example: "1. COPD exacerbation (J44.1) — moderate severity as above. 2. Hypertension (I10) — well controlled, BP 128/78 on current regimen. 3. Type 2 DM (E11.65) — HbA1c 8.2%, above goal, hyperglycemia likely exacerbated by corticosteroid use."
SOAP Note Assessment Examples by Specialty
The following soap note assessment examples demonstrate how different specialties approach the assessment section. Each example shows realistic clinical reasoning that connects subjective and objective data to diagnostic conclusions. Use these as templates when writing your own assessments.
1. Type 2 diabetes mellitus with hyperglycemia (E11.65) — Suboptimally controlled. HbA1c 8.4% (up from 7.8% three months ago). Patient reports dietary non-adherence during holiday season and inconsistent use of metformin due to GI side effects. Fasting glucose today 186 mg/dL. No signs of diabetic retinopathy on recent ophthalmology exam. Microalbumin/creatinine ratio 42 mg/g (mildly elevated), suggesting early nephropathy. Risk for progression to overt nephropathy if glycemic control does not improve.
2. Essential hypertension (I10) — Adequately controlled. BP 132/82 today on lisinopril 20 mg daily. ACE inhibitor serving dual purpose for renal protection given early diabetic nephropathy.
3. Obesity, BMI 33.2 (E66.01) — Stable. Weight 218 lbs, unchanged from last visit. Contributing to insulin resistance and glycemic control challenges. Patient expressed interest in GLP-1 agonist therapy for weight and glucose management.
1. Major depressive disorder, recurrent episode, moderate (F33.1) — Partial response to sertraline 100 mg daily after 8 weeks. PHQ-9 score decreased from 19 (moderately severe) to 14 (moderate). Patient reports improved sleep onset and appetite but continues to endorse persistent anhedonia, difficulty concentrating at work, and social withdrawal. Denies suicidal ideation, intent, or plan. No psychotic features. Functional impairment remains significant — called out of work 4 days this month.
2. Generalized anxiety disorder (F41.1) — Comorbid anxiety contributing to insomnia and concentration difficulties. GAD-7 score 12 (moderate). Anxiety appears intertwined with depressive symptoms — difficult to fully distinguish contribution of each disorder to functional impairment. Consider whether inadequate anxiety management is limiting depression treatment response.
Clinical reasoning: Given partial response at 8 weeks on adequate dose, augmentation or dose optimization warranted. Residual anhedonia and concentration impairment may respond to augmentation. Rule out hypothyroidism or other medical contributors to fatigue and cognitive complaints — TSH and CBC ordered. For more detailed psychiatric SOAP note examples, see our dedicated guide.
1. Lumbar radiculopathy, right side (M54.11) — Patient presents with 6-week history of low back pain radiating to right posterior thigh and lateral calf, consistent with L5 radiculopathy. Positive straight leg raise at 40 degrees on the right. Decreased sensation to light touch over L5 dermatome. MRI (obtained prior to visit) shows L4-L5 disc protrusion with right foraminal narrowing. No red flags identified — no saddle anesthesia, bowel/bladder dysfunction, or progressive motor weakness.
2. Impaired lumbar mobility (M99.03) — Lumbar flexion limited to 40% of expected range with centralization of symptoms during repeated extension. McKenzie classification: derangement syndrome, reducible. This is a favorable prognostic indicator.
Prognosis: Good for functional recovery. Centralization response and absence of red flags predict positive outcomes with conservative management. Rehabilitation potential is excellent given patient's motivation, younger age (34), and active baseline. Expected return to full function in 6-8 weeks with consistent participation in therapy 2x/week.
1. Chest pain, unspecified (R07.9) — workup in progress — 58-year-old male presenting with acute substernal chest pressure radiating to left jaw, onset 3 hours prior to arrival, associated with diaphoresis and dyspnea. History significant for HTN, hyperlipidemia, smoking (30 pack-years), and family history of MI in father at age 52. HEART score 7 (high risk). Initial troponin 0.04 ng/mL (borderline — serial troponin pending). ECG shows nonspecific ST-T wave changes in leads V4-V6 without acute ST elevation.
Assessment of risk: High clinical suspicion for acute coronary syndrome (ACS) based on typical presentation, multiple cardiac risk factors, and HEART score. Serial troponins will determine NSTEMI vs. unstable angina. For detailed emergency medicine coding, this encounter supports high-complexity MDM.
Differentials: Aortic dissection (less likely — pain is pressure-type not tearing, BP symmetric bilaterally, no mediastinal widening on CXR). Pulmonary embolism (low probability — no pleuritic component, no unilateral leg swelling, Wells score 1.5). Esophageal spasm (possible but pain pattern and risk factors favor cardiac etiology). GERD (less likely given associated diaphoresis and radiation pattern).
1. Surgical wound, left knee — post total knee arthroplasty, POD 2 (Z96.652) — Wound healing is progressing as expected. Incision is well-approximated with staples intact (26 count), mild serous drainage on dressing (small spot, approximately 3 cm in diameter), no erythema beyond expected peri-incisional changes (less than 1 cm margin), no warmth or induration suggesting infection. Patient reports pain at surgical site rated 5/10, which is decreased from 7/10 yesterday with current pain management regimen.
2. Risk for venous thromboembolism (Z79.01) — Patient is on enoxaparin 40 mg SQ daily for DVT prophylaxis per surgical protocol. No calf tenderness, swelling, or Homans sign. Sequential compression devices in place and functioning. Patient ambulated 50 feet with rolling walker this morning with PT assistance. Mobility progression is on track for POD 2. For more nursing SOAP note examples, see our nursing-specific guide.
1. Acute otitis media, right ear (H66.91) — 4-year-old male with 3-day history of right ear pain, fever (101.8 F), and irritability. Otoscopic exam reveals erythematous, bulging tympanic membrane with decreased mobility on pneumatic otoscopy, consistent with acute otitis media. Left ear normal. No signs of perforation or otorrhea. This is the second episode in 6 months — does not yet meet criteria for recurrent AOM (three or more episodes in 6 months).
Differential: Otitis media with effusion (less likely given fever, bulging TM, and acute symptoms). Otitis externa (less likely — no tragal tenderness, canal non-edematous). Referred dental pain (no dental caries identified on oral exam).
2. Upper respiratory infection, viral (J06.9) — Concurrent rhinorrhea and mild cough for 5 days, likely predisposing factor for AOM. No lower respiratory findings. Lungs clear bilaterally. Supportive care appropriate.
Common SOAP Note Assessment Mistakes
Even experienced clinicians make documentation errors in the assessment section. The following table highlights the most common mistakes in SOAP notes assessments alongside improved examples that demonstrate proper clinical reasoning. Avoiding these pitfalls will strengthen your documentation, support appropriate E/M coding, and reduce audit risk.
| Mistake | Bad Example | Better Example |
|---|---|---|
| Too vague | "Patient is sick. Will treat." | "Community-acquired pneumonia (J18.9), moderate severity. Right lower lobe infiltrate on CXR with productive cough, fever 102.1F, and WBC 14,200 support infectious etiology." |
| Repeating S/O data | "Patient has cough, fever, and abnormal chest X-ray." | "Clinical presentation (productive cough, fever, lobar consolidation) is consistent with bacterial pneumonia. CURB-65 score 1 — appropriate for outpatient management." |
| Missing differentials | "Diagnosis: Pneumonia." | "Pneumonia (J18.9) most likely. Differential includes TB (unlikely, no risk factors or cavitary lesion), lung malignancy (low risk given age 32, but follow-up CXR in 6 weeks to confirm resolution)." |
| No ICD-10 codes | "Patient has diabetes and high blood pressure." | "1. Type 2 DM with hyperglycemia (E11.65), HbA1c 8.4%. 2. Essential hypertension (I10), controlled on current regimen." |
| Not addressing all problems | "Diabetes controlled." (Ignores HTN, CKD, and obesity also discussed in visit) | "1. T2DM (E11.65) — improved. 2. HTN (I10) — controlled. 3. CKD Stage 3a (N18.31) — stable. 4. Obesity BMI 34 (E66.01) — counseled on weight management." |
| Lack of clinical reasoning | "Assessment: UTI." | "Uncomplicated cystitis (N30.00). Dysuria, frequency, and positive UA (leukocyte esterase+, nitrites+) in premenopausal female without fever or flank pain support lower tract infection. No features of pyelonephritis." |
Assessment vs. Plan: Understanding the Difference
One of the most common sources of confusion in SOAP note writing is the boundary between the Assessment and Plan sections. Many clinicians blur these sections — sometimes combining them as "A/P" — but understanding the distinction leads to clearer documentation and stronger clinical communication.
Assessment = What You Think
The assessment answers: "What do I believe is going on with this patient?"
- Diagnoses and clinical impressions
- Differential diagnoses
- Clinical reasoning and interpretation
- Severity and prognosis
- ICD-10 codes
Plan = What You Will Do
The plan answers: "What am I going to do about it?"
- Medications prescribed or adjusted
- Diagnostic tests ordered
- Referrals and consultations
- Patient education provided
- Follow-up scheduling
Example: Separating Assessment from Plan
Assessment
Acute bacterial sinusitis (J01.90). Patient presents with 12 days of nasal congestion, purulent drainage, facial pressure over maxillary sinuses, and low-grade fever. Symptoms initially improved then worsened ("double sickening" pattern), consistent with secondary bacterial infection following viral URI. No orbital or intracranial complications suspected.
Plan
1. Start amoxicillin-clavulanate 875/125 mg BID x 10 days. 2. Nasal saline irrigation TID. 3. Acetaminophen or ibuprofen PRN for pain/fever. 4. Return if symptoms worsen or no improvement in 72 hours. 5. Patient education: complete full antibiotic course, adequate hydration, head elevation during sleep.
While some clinicians and EHR systems combine Assessment and Plan as "A/P," keeping them conceptually distinct improves documentation clarity. The SOAPIE and SOAPE formats further separate these elements, adding Intervention and Evaluation sections for even more granular documentation. See also our guides to progress notes and clinical notes templates for alternative documentation approaches.
AI-Assisted SOAP Note Assessment Writing
Writing thorough assessments for every patient encounter is time-consuming, and documentation burden is a leading contributor to clinician burnout. AI-powered documentation tools can significantly reduce the time spent on SOAP clinical assessment writing while maintaining quality and completeness.
PatientNotes uses AI to listen to patient encounters and automatically generate complete SOAP notes, including detailed assessment sections with ICD-10 codes, differential diagnoses, and clinical reasoning. The AI draws on clinical guidelines and the encounter context to produce assessments that reflect the complexity of the visit.
ICD-10 Code Lookup
Automatically suggests the most specific ICD-10 codes based on clinical findings documented in the encounter.
Differential Diagnosis
Generates comprehensive differential diagnosis lists with reasoning for and against each possibility based on the clinical presentation.
SOAP Note Generator
Creates complete SOAP notes from encounter audio or text, with fully formed assessment sections ready for clinician review.
How AI Improves Assessment Quality
- Reduces omissions: AI ensures all problems discussed in the encounter are addressed in the assessment, reducing the risk of undocumented diagnoses.
- ICD-10 specificity: AI cross-references clinical data against the full ICD-10 code set to suggest the most specific code, avoiding unspecified codes that can trigger audits.
- Differential completeness: AI prompts consideration of differential diagnoses that might be overlooked during a busy clinical day.
- Time savings: Clinicians report saving 10-15 minutes per note when AI generates the initial assessment draft, allowing more time for patient care.
AI-generated assessments should always be reviewed and approved by the treating clinician. The AI serves as a documentation assistant, not a replacement for clinical judgment. Pair AI assessment generation with the ROS checklist tool to ensure comprehensive documentation across the entire SOAP note.
Frequently Asked Questions About SOAP Note Assessments
What is the assessment in a SOAP note?
The assessment in a SOAP note is the clinician's clinical reasoning section where they synthesize the subjective (patient-reported) and objective (measurable findings) data to form diagnoses, differential diagnoses, and clinical impressions. It represents the "thinking" part of the note — where raw data from the patient interview and examination is interpreted into actionable clinical conclusions. The assessment bridges the gap between gathering information and making treatment decisions.
What should be included in a SOAP note assessment?
A complete SOAP note assessment should include: the primary diagnosis or clinical impression with ICD-10 codes, differential diagnoses with reasoning for and against each, clinical reasoning that explicitly connects subjective and objective findings to the diagnosis, disease severity or staging, prognosis when relevant, response to current treatment for follow-up visits, and risk stratification when applicable. Not every assessment will include all elements — the depth depends on visit complexity and clinical context.
How do you write an assessment for a SOAP note?
To write an effective assessment soap note, follow these steps: (1) Start with the primary diagnosis supported by key findings from the S and O sections. (2) Include the ICD-10 code for specificity. (3) List differential diagnoses with brief reasoning for or against each. (4) Note disease severity and prognosis. (5) For follow-up visits, document response to current treatment. (6) Address all active problems using a numbered problem list format. The goal is to demonstrate your clinical reasoning process, not merely repeat data from earlier sections.
What is the difference between assessment and plan in SOAP notes?
The assessment section answers "What do I think is going on?" while the plan section answers "What am I going to do about it?" The assessment contains your diagnoses, clinical reasoning, differential diagnoses, and interpretation of findings. The plan contains your treatment decisions — medications, procedures, referrals, diagnostic tests ordered, patient education, and follow-up scheduling. Some EHR systems and clinicians combine them as "A/P," but they serve conceptually distinct documentation purposes. Keeping them separate improves clarity for other providers reviewing the note.
Should ICD-10 codes be included in the assessment?
Yes, including ICD-10 codes in the assessment is considered best practice. ICD-10 codes provide standardized diagnostic language, support accurate billing and reduce claim denials, facilitate communication between providers, and ensure documentation specificity. Use the most specific code available — for example, "E11.65 — Type 2 diabetes mellitus with hyperglycemia" rather than the unspecified "E11.9." Including codes directly in the assessment also speeds up the billing process and reduces coding errors.
How long should a SOAP note assessment be?
The length of a SOAP notes assessment varies by visit complexity. A straightforward follow-up for a single stable problem might have a 2-3 sentence assessment (50-75 words). A complex new patient evaluation with multiple active problems could require a full paragraph per problem (200-400 words total). The key principle is being thorough enough to demonstrate your clinical reasoning without being redundant — every sentence should add interpretive value beyond what is already documented in the S and O sections.
Can AI write SOAP note assessments?
Yes, AI-powered tools like PatientNotes can generate SOAP clinical assessment sections from patient encounter data. AI can listen to the clinical encounter, extract relevant findings, suggest differential diagnoses, recommend appropriate ICD-10 codes, and draft clinical reasoning that connects subjective and objective data to diagnostic conclusions. However, AI-generated assessments must always be reviewed and approved by the treating clinician to ensure clinical accuracy, appropriateness, and alignment with the clinician's professional judgment.
What are common mistakes in SOAP note assessments?
The most common mistakes include: being too vague (e.g., "patient is sick" without a specific diagnosis), simply repeating subjective and objective data without adding clinical interpretation, omitting differential diagnoses, not including ICD-10 codes, failing to address all problems identified during the encounter, not connecting findings to clinical reasoning, and blurring the line between assessment and plan content. An effective assessment demonstrates the clinician's diagnostic thinking process and provides enough detail to justify the level of medical decision-making billed.
