F15.93 — Other stimulant use, unspecified with withdrawal
F15.93 is a billable, specific ICD-10-CM code for other stimulant use, unspecified with withdrawal. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.

- Caffeine withdrawal
Excludes1 inherited from the categories above F15.93
These are not written on F15.93, but they bind it: a note on a category applies to every code beneath it. Billing F15.93 with anything listed here is a denial.
Excludes2 inherited from the categories above F15.93
Also inherited, and the opposite of Excludes1: these conditions are not part of F15.93, but a patient can have both, so you may code both.
Other codes that can never be billed with F15.93
These codes carry an Excludes1 note pointing at F15.93. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F15.93 alone.
- F15.92Other stimulant use, unspecified with intoxication
Risk adjustment
F15.93 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:
- HCC 137 Drug Use Disorder, Moderate/Severe, or Drug Use with Non-Psychotic Complications0.424 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.
