ICD-10 Code F66 – Other sexual disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F66 – Other sexual disorders
What it is
F66 covers sexual disorders that do not fit a more specific ICD-10 diagnosis. Use it for documented sexual dysfunctions or concerns that are identified clinically but remain otherwise unspecified.
Clinical signs
Clinical features vary; refer to documentation. Records may note distress, impaired sexual functioning, or atypical sexual concerns without a clearer diagnostic category.
When to use this code
Use F66 when the provider documents an other sexual disorder and does not name a more specific code. It may apply when the chart describes a sexual problem but gives limited detail. Verify the diagnosis wording before coding.
Do not use for
Do not use F66 when the record supports a more specific sexual disorder code. Check documentation to avoid coding normal relationship concerns, nonclinical sexual behavior, or unrelated psychiatric conditions.
Coding tip
Code the most specific documented sexual disorder first; use F66 only when the provider’s wording remains nonspecific.
