ICD-10 Code F11.981 – Opioid use, unspecified with opioid-induced sexual dysfunction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F11.981 – Opioid use, unspecified with opioid-induced sexual dysfunction
What it is
This code identifies opioid use, unspecified when the patient has sexual dysfunction caused by the opioid. Use it when the record links the sexual problem to opioid use but does not specify a more detailed opioid-related diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Common charted findings include decreased libido, erectile dysfunction, delayed orgasm, or other sexual dysfunction noted as opioid-induced.
When to use this code
Use this code when the provider documents opioid use and explicitly states the sexual dysfunction is opioid-induced. It is appropriate when the opioid-related disorder is unspecified and the sexual effect is part of the clinical assessment. Check documentation if the cause is unclear or another substance is involved.
Do not use for
Do not use this code if sexual dysfunction is not linked to opioid use, or if a different substance or medical condition is documented as the cause. Check documentation when the opioid-related diagnosis is more specific.
Coding tip
Code only when the provider clearly connects the sexual dysfunction to opioid use in the record.
