Common Documentation Mistakes for CPT 90837
- Vague Symptom Documentation: Avoid generic statements like "client reports doing okay." Be specific about which symptoms are present, which have improved, and which persist.
- Missing Time/Complexity Justification: Don't simply bill the code; document why this encounter required the time and complexity represented by the code you're billing.
- Insufficient Medical Necessity: Always connect symptoms to diagnosis and show how treatment addresses the documented symptoms and functional impairment.
- Incomplete Risk Assessment: If mental health treatment is involved, address safety. Document suicide risk assessment, substance use status, or other safety factors as appropriate.
- Generic Treatment Plans: "Continue current therapy" is insufficient. Specify what you're doing and why, with reference to the client's goals and presenting problems.
- Inconsistent Diagnoses: Ensure your billing diagnoses match your documentation. If you bill for depression, document depressive symptoms. If you bill for anxiety, document anxiety symptoms.
- Missing Progress Indicators: Show how the client is progressing. Compare to previous session, note improvements, identify barriers, adjust interventions based on response.
Audit Red Flags for CPT 90837
Insurance auditors and peer reviewers look for these red flags when reviewing claims for CPT 90837:
- Documentation that doesn't support the complexity or time of the code billed
- Inconsistency between diagnosis billed and symptoms documented
- Lack of progress notes over time (shows ongoing medical necessity)
- Missing risk assessment when treating mental health conditions
- Generic, template-like notes that could apply to any client
- No clear treatment plan or goals documented
- Inadequate functional assessment (documentation of how condition affects daily life)
- Notes that don't reflect the time reported (very brief notes for longer billing times)
Sample Note Example for PIE Notes for CPT 90837
Intervention: Provided a 53-minute individual psychotherapy session focused on CBT-informed intervention, including identification of automatic thoughts related to failure, cognitive restructuring, grounding, and behavioral activation planning. Therapist explored current stressors, reinforced coping skills, and practiced a brief in-session breathing exercise to reduce physiological arousal. Session also included supportive therapy and problem-solving around work boundaries and sleep routine.
Evaluation: Client was alert and oriented x4, maintained eye contact, and participated actively throughout the full session. Client demonstrated insight into the connection between catastrophic thinking and avoidance, and was able to generate two realistic alternative thoughts. Symptoms remain clinically significant and continue to impair functioning, supporting the medical necessity for extended psychotherapy consistent with CPT 90837. Client left session reporting decreased distress and willingness to practice skills before next visit.

Documentation Considerations for PIE Notes for CPT 90837
Document Medical Necessity Beyond Time Alone
CPT 90837 is an individual psychotherapy code for sessions of 53 minutes or more, but time alone does not justify the code. Your PIE note should clearly show why the extended session was clinically necessary: severity of symptoms, functional impairment, acuity, risk management, or the need for more intensive therapeutic work. Payers look for evidence that the longer duration addressed a specific treatment need, not just a lengthy conversation.
Record the Time Frame Precisely
For 90837, document the psychotherapy duration in a way that supports the code’s time threshold. Many audits focus on whether the actual psychotherapy time reached 53 minutes or more, not just the appointment slot length. Note the start and stop time or the total face-to-face psychotherapy minutes when your practice requires it. Avoid vague phrases like “seen for an hour” unless your payer and documentation policy accept that level of specificity.
Watch Payer Variations and Authorization Rules
Some payers scrutinize 90837 more closely than 90832 because of its higher reimbursement and longer duration. Check whether the payer requires prior authorization, frequency limits, modifier use, or specific diagnosis-linking language. In your PIE note, keep the treatment focus aligned with the diagnosed condition and current treatment plan. If telehealth is used, ensure the note also reflects location and modality requirements imposed by the payer.
Avoid Common Audit Triggers
Common red flags include identical notes, generic interventions, missing symptom change, no linkage to goals, and no explanation for why the session needed to be 53+ minutes. Auditors may also question 90837 if the note reflects brief check-in content, minimal therapist intervention, or no measurable functional impact. PIE notes should show a clear problem, a clinically relevant intervention, and an evaluation of the client’s response and ongoing need for treatment.
FAQ — PIE Notes for CPT 90837
What makes a PIE note support CPT 90837 instead of a shorter psychotherapy code?
A PIE note should show that the session involved at least 53 minutes of individual psychotherapy and that the extended time was clinically warranted. For 90837, the note should reflect a substantial therapeutic intervention, not just supportive conversation or a routine check-in. The Problem section should identify symptoms and functional impairment, the Intervention section should show active psychotherapy techniques, and the Evaluation should describe the client’s response and ongoing need for treatment.
Do I need to write the exact start and stop time for a CPT 90837 note?
Not every payer requires start and stop times, but documenting them is a strong best practice for CPT 90837 because it clearly supports the 53-minute threshold. If your workflow uses total psychotherapy minutes, make sure it is unambiguous and consistent with your policy. The key is that the record should prove the session met the time requirement and was not simply booked for an hour.
How specific should the medical-necessity language be in a PIE note for 90837?
Very specific. The note should connect symptoms to real functional impairment and explain why a longer psychotherapy session was needed. For example, identify disrupted work performance, severe anxiety, trauma processing, or risk-related complexity that required extra time. Generic phrases like “patient discussed stressors” are usually insufficient. Payers expect documentation that supports the intensity and duration of treatment, not just the diagnosis code.
What are the most common reasons 90837 claims get denied or audited?
Common reasons include lack of proof that the session reached 53 minutes, notes that look too brief or repetitive, interventions that do not appear to be psychotherapy, and missing links between symptoms and treatment goals. Another frequent issue is using 90837 for sessions that read like medication management, crisis-only contacts, or casual support. Strong PIE notes should show psychotherapy content, patient progress or lack of progress, and why continued extended sessions remain medically necessary.
