A long-lasting mood disorder that is not further specified or categorized by the provider.
Coding Tips
- •This is a catch-all code for persistent mood disorders when the specific type cannot be determined
- •Query the provider to determine if the condition is cyclothymia or another specific persistent mood disorder
Clinical Significance
Persistent mood disorder, unspecified, is used when a provider documents a chronic mood disorder but does not specify the type. Under V24 it maps to HCC 59 with a RAF of 0.309, giving it the same risk adjustment value as specified persistent mood disorders. However, use of unspecified codes is generally discouraged in risk adjustment as it may trigger auditor scrutiny and suggests incomplete clinical documentation.
Documentation Requirements
- ✓Provider statement confirming a persistent (chronic) mood disorder
- ✓Duration of symptoms consistent with a persistent pattern (not episodic)
- ✓Current symptoms and their impact on functioning
- ✓Mental status examination findings
- ✓Current treatment regimen (medications, therapy)
- ✓Documentation explaining why a more specific mood disorder cannot be determined
