0.000What This Code Means
Bipolar disorder where the person is currently experiencing a hypomanic episode, which is a less severe form of mania lasting at least 4 consecutive days with elevated mood and increased activity.
Coding Tips
- •Hypomanic episodes are milder than manic episodes and do not cause significant functional impairment or require hospitalization
- •Ensure documentation clearly distinguishes between hypomanic and manic episodes, as this affects severity coding
Clinical Significance
Bipolar disorder with current hypomanic episode represents a less severe manic state that may not require inpatient intervention but still demands active psychiatric management. Hypomania is clinically significant because it often precedes full manic or depressive episodes and indicates an unstable mood state. Accurate capture supports risk-adjusted resource allocation for ongoing medication management and relapse prevention.
Documentation Requirements
- ✓Documented diagnosis of bipolar disorder with history of at least one prior manic or depressive episode
- ✓Current symptoms consistent with hypomania (elevated or irritable mood lasting at least 4 consecutive days)
- ✓Functional assessment showing the episode does not cause marked impairment or require hospitalization
- ✓Absence of psychotic features documented
- ✓Current psychiatric medications and treatment plan
