ICD-10 Code F11.98 – Opioid use, unspecified with other specified opioid-induced disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F11.98 – Opioid use, unspecified with other specified opioid-induced disorder
What it is
This code identifies opioid use when the record documents a related opioid-induced disorder that does not fit a more specific category. Use it when the clinician links opioid use to another specified substance-induced condition.
Clinical signs
Clinical features vary; refer to documentation. The chart should show opioid use plus a clearly described opioid-induced disorder that is not otherwise classified under a more specific code.
When to use this code
Use F11.98 when the provider documents opioid use and names a specific opioid-induced disorder, but no more precise ICD-10 option is available. This may apply when the note describes a substance-induced condition tied to opioids and explicitly states another specified disorder. Check documentation if the relationship is unclear.
Do not use for
Do not use this code for uncomplicated opioid use, opioid dependence, or opioid abuse without the documented induced disorder. Also avoid it when a more specific opioid-induced code is supported by the record.
Coding tip
Confirm both the opioid use and the exact induced disorder in the provider note before assigning F11.98.
