ICD-10 Code F11.93 – Opioid use, unspecified with withdrawal (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F11.93 – Opioid use, unspecified with withdrawal
What it is
F11.93 identifies opioid use disorder or opioid-related use when the specific opioid is not named and the patient is experiencing withdrawal. Use it when documentation supports withdrawal symptoms tied to opioid cessation or reduction.
Clinical signs
Typical withdrawal features include restlessness, anxiety, sweating, yawning, rhinorrhea, lacrimation, abdominal cramping, nausea, or muscle aches. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states opioid use, unspecified, and documents withdrawal. It may fit emergency, outpatient, or inpatient notes describing withdrawal after stopping opioids or reducing use. Check documentation if the opioid type or disorder severity is specified elsewhere.
Do not use for
Do not use it for opioid intoxication, dependence without withdrawal, or use of a named opioid when a more specific code is documented. Do not guess if withdrawal is not clearly stated.
Coding tip
Confirm both opioid use and withdrawal are documented before assigning F11.93.
