F12.99 — Cannabis use, unspecified with unspecified cannabis-induced disorder
Is F12.99 billable?
Yes, but F12.99 is an unspecified code. F12.99 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, F12.99 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 F12.99 — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from F12.9
The conditions below can never be reported together with F12.99 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from Chapter 5
The conditions below are not part of F12.99, but a patient may have both at the same time. When documentation supports it, F12.99 and the excluded code may both be reported.
