F30.12 is a billable ICD-10-CM diagnosis code for manic episode without psychotic symptoms, moderate. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 885. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 292 closely related codes. Coders also document this condition as manic disorder, single episode. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Bipolar and related disorders.
For Medicare Advantage risk adjustment, F30.12 maps to CMS-HCC Category 154 (Bipolar Disorders without Psychosis) under the V28 model, adding a risk factor of about 0.351 for a community, non-dual, aged beneficiary in payment year 2027.
