Compatibility Notes
Appropriate for maintenance-phase MDD patients in remission or with mild recurrent symptoms who benefit from brief, regular check-ins. This combination is accepted by most payers for step-down care. If the patient's condition worsens, upgrade to 90834 or 90837 and update the diagnosis specifier accordingly.
Documentation Required
- ✓Session start and stop times confirming 16–37 minutes
- ✓Documentation that the patient is in maintenance phase or experiencing mild recurrence
- ✓PHQ-9 score in mild range (5–9) or equivalent narrative
- ✓Rationale for 30-minute format (stable, maintenance-phase patient)
- ✓Updated treatment plan objectives reflecting maintenance goals
Common Denial Reasons
- ✗PHQ-9 or documented symptom severity inconsistent with "mild" specifier — if scores suggest moderate/severe, insurer may question the downgraded code
- ✗Session time outside the 16–37 minute range
- ✗Notes copied forward without session-specific content

Reimbursement Notes
OON UCR is $75–$125. For maintenance-phase patients this combination has a reasonable ROI when volume is high. Commercial plan reimbursement typically $40–$85 after deductible.
