F30.4 is a billable ICD-10-CM diagnosis code for manic episode in full remission. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 885. Coders also document this condition as bipolar disorder in full remission. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Mental and substance use disorders in remission.
F30.4 no longer risk-adjusts for Medicare Advantage: it mapped to HCC 59 under the retired CMS-HCC V24 model through payment year 2025 but maps to no category in the live V28 model. It still risk-adjusts in the PACE (CMS-HCC V22) category 58, ESRD (V21) category 58, ESRD (V24) category 59, and RxHCC Part D (V08) category 131 for payment year 2027.

Questions About F30.4Overview
What is the ICD-10 code for manic episode in full remission?
The ICD-10-CM code for manic episode in full remission is F30.4 (sometimes written as F304). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is F30.4 (Manic episode) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report manic episode in full remission on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does F30.4 group to?
When manic episode in full remission is the principal diagnosis on an inpatient stay, it groups to MS-DRG 885 (psychoses), which carries a relative weight of 1.3904. Higher weights mean higher Medicare reimbursement.
Can F30.4 be reported with a code from F31?
Not as a rule. The Excludes1 note at F30, which applies to F30.4, lists "bipolar disorder (F31.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
What is the ICD-9 equivalent of F30.4?
Under the General Equivalence Mappings, manic episode in full remission converts to ICD-9-CM 296.06 (bipol I single manic rem). The mapping is approximate, so confirm the match fits the documentation.
Does F30.4 risk-adjust for Medicare Advantage payment?
Not for Medicare Advantage. F30.4 mapped to HCC 59 in the retired CMS-HCC V24 model, which last determined payment in 2025, but it maps to no category in the live V28 model; see all codes that no longer risk-adjust. It still risk-adjusts in the PACE (CMS-HCC V22) category 58 (Major Depressive/Bipolar/and Paranoid Disorders), ESRD (V21) category 58 (Major Depressive/Bipolar/and Paranoid Disorders), ESRD (V24) category 59 (Major Depressive/Bipolar/and Paranoid Disorders), and RxHCC Part D (V08) category 131 (Bipolar Disorders).
