F11.23 — Opioid dependence with withdrawal
F11.23 is a billable, specific ICD-10-CM code for opioid dependence 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.
- opioid dependence with intoxication (F11.22-)
Other codes that can never be billed with F11.23
These codes carry an Excludes1 note pointing at F11.23. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F11.23 alone.
- F11.22Opioid dependence with intoxication
Risk adjustment
F11.23 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.
