F31.71 — Bipolar disorder, in partial remission, most recent episode hypomanic
F31.71 is a billable, specific ICD-10-CM code for bipolar disorder, in partial remission, most recent episode hypomanic. It is valid for submission on a claim.
Excludes1 inherited from the categories above F31.71
These are not written on F31.71, but they bind it: a note on a category applies to every code beneath it. Billing F31.71 with anything listed here is a denial.
Excludes2 inherited from the categories above F31.71
Also inherited, and the opposite of Excludes1: these conditions are not part of F31.71, but a patient can have both, so you may code both.
Other codes that can never be billed with F31.71
These codes carry an Excludes1 note pointing at F31.71. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F31.71 alone.
Risk adjustment
F31.71 risk-adjusts. Under the CMS-HCC V28 model it maps to these categories:
- HCC 154 Bipolar Disorders without Psychosis0.351 RAF
- HCC 154 Bipolar Disorders without Psychosis0.351 RAF
Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.
Medicare coverage
F31.71 is named in 23 Medicare coverage policies — 22 listing it as supporting medical necessity, and 1 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
