Is F31.5 a billable ICD-10-CM code?

Yes. F31.5 is a billable, specific ICD-10-CM code and is valid for submission on a claim.

Where does F31.5 sit in the tabular list?

Mental, Behavioral and Neurodevelopmental disorders (F01-F99), in the block Mood [affective] disorders (F30-F39).

What cannot be coded together with F31.5?

F31.5 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above F31.5 (F31) and apply to it just the same.

F31.5

F31.5 — Bipolar disorder, current episode depressed, severe, with psychotic features

Billable / specific codeICD-10-CM

F31.5 is a billable, specific ICD-10-CM code for bipolar disorder, current episode depressed, severe, with psychotic features. It is valid for submission on a claim.

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Bipolar disorder, current episode depressed with mood-incongruent psychotic symptoms
Bipolar disorder, current episode depressed with mood-congruent psychotic symptoms
Bipolar I disorder, current or most recent episode depressed, with psychotic features

Excludes1 inherited from the categories above F31.5

These are not written on F31.5, but they bind it: a note on a category applies to every code beneath it. Billing F31.5 with anything listed here is a denial.

Written on F31 — Bipolar disorder

bipolar disorder, single manic episode (F30.-)
major depressive disorder, single episode (F32.-)
major depressive disorder, recurrent (F33.-)

Excludes2 inherited from the categories above F31.5

Also inherited, and the opposite of Excludes1: these conditions are not part of F31.5, but a patient can have both, so you may code both.

Written on F31 — Bipolar disorder

cyclothymia (F34.0)

Other codes that can never be billed with F31.5

These codes carry an Excludes1 note pointing at F31.5. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F31.5 alone.

F20Schizophrenia
F22Delusional disorders
F25Schizoaffective disorders
F30Manic episode
F32Depressive episode
F33Major depressive disorder, recurrent
F53Mental and behavioral disorders associated with the puerperium, not elsewhere classified
R44Other symptoms and signs involving general sensations and perceptions

Risk adjustment

F31.5 risk-adjusts. Under the CMS-HCC V28 model it maps to these categories:

HCC 152 Psychosis, Except Schizophrenia0.484 RAF
HCC 152 Psychosis, Except Schizophrenia0.484 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

F31.5 is named in 26 Medicare coverage policies — 25 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.

A52434Health and Behavior Assessment/Intervention – Medical Policy Articlenot covered
A56614Billing and Coding: Psychiatric Inpatient Hospitalization
A56645Billing and Coding: Controlled Substance Monitoring and Drugs of Abuse Testing
A56685Billing and Coding: Partial Hospitalization Programs

How F31.5 is indexed
