F19.94 — Other psychoactive substance use, unspecified with psychoactive substance-induced mood disorder

BillableUnspecified

Is F19.94 billable?

Yes, but F19.94 is an unspecified code. F19.94 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, F19.94 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting F19.94 — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from F19.9

The conditions below can never be reported together with F19.94 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

other psychoactive substance dependence (F19.2-)

Excludes2 — not included here — inherited from Chapter 5

The conditions below are not part of F19.94, but a patient may have both at the same time. When documentation supports it, F19.94 and the excluded code may both be reported.

symptoms, signs and abnormal clinical laboratory findings, not elsewhere classified (R00-R99)
