ICD-10 Code
F33.9
Major depressive disorder, recurrent, unspecified
Common Modifiers
Compatibility Notes
Used for recurrent MDD when the current episode severity has not been specified. Acceptable as a transitional code when severity assessment is pending, but most payers prefer a specifier code (F33.0–F33.1) after the initial sessions. Chronic use of the unspecified recurrent MDD code may prompt utilization review.
Documentation Required
- ✓Session start and stop times confirming 53+ minutes
- ✓Documented prior MDD episode confirming recurrent course
- ✓Clinical justification for unspecified severity (assessment pending)
- ✓PHQ-9 or equivalent to be completed within 1–2 sessions
- ✓Risk assessment
Common Denial Reasons
- ✗Unspecified code used long-term without a severity specifier being established
- ✗No documentation of prior episode establishing recurrent course
- ✗Session time below 53 minutes
Applicable Modifiers
Reimbursement Notes
OON UCR $130–$210, consistent with all 90837 pairings. Severity specifier codes typically process more cleanly; refine to F33.0, F33.1, or higher as soon as severity is established.
