ICD-10-CM Codes for Methamphetamine and Fentanyl Withdrawal
For methamphetamine withdrawal, use F15.23 (Other stimulant dependence with withdrawal). For fentanyl withdrawal, use F11.23 (Opioid dependence with withdrawal).
Methamphetamine Withdrawal Coding
Methamphetamine is classified as a CNS stimulant 1. The appropriate ICD-10-CM code is:
- F15.23 - Other stimulant dependence with withdrawal
This code captures amphetamine-type stimulants including methamphetamine when withdrawal symptoms are present. The code applies when patients exhibit withdrawal features after cessation of chronic methamphetamine use.
Fentanyl Withdrawal Coding
Fentanyl is classified as an opioid agonist 1. The appropriate ICD-10-CM code is:
- F11.23 - Opioid dependence with withdrawal
This code specifically captures opioid withdrawal syndrome, which includes fentanyl withdrawal 1. The clinical presentation includes CNS irritability, autonomic overreactivity, and gastrointestinal dysfunction 1.
Additional Relevant Codes
Depending on the clinical context, you may also need:
- F11.20 - Opioid dependence, uncomplicated (if withdrawal not currently present)
- F15.20 - Other stimulant dependence, uncomplicated (if withdrawal not currently present)
- F11.21 - Opioid dependence, in remission (for patients in recovery)
- F15.21 - Other stimulant dependence, in remission (for patients in recovery)
Important Coding Considerations
The ICD-10-CM codes for substance use disorders underwent significant updates from ICD-9 to ICD-10, providing more granular classification 2. The F11.23 code specifically identifies withdrawal states, which is critical for accurate surveillance and treatment planning 1.
For polysubstance use involving both methamphetamine and fentanyl (increasingly common 3, 4), both codes should be assigned to capture the full clinical picture. Research indicates that ICD-10-CM codes have high sensitivity (≥79%) and positive predictive value (≥92%) for identifying withdrawal syndromes when properly applied 5.
A common pitfall: The codes F11.90 (opioid use, unspecified) and F15.90 (stimulant use, unspecified) are less specific and should be avoided when withdrawal is documented, as they lack the specificity needed for accurate clinical documentation and surveillance 6.
