ICD-10 Code F52.9 – Unspecified sexual dysfunction not due to a substance or known physiological condition (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F52.9 – Unspecified sexual dysfunction not due to a substance or known physiological condition
What it is
This code identifies a sexual dysfunction that is not explained by a substance, medication, or known physiological condition. Use it when the record confirms sexual dysfunction but does not specify the exact type.
Clinical signs
Clinical features vary; refer to documentation. Notes may describe reduced sexual response, difficulty with desire, arousal, orgasm, or pain during sex, but the exact pattern is not documented.
When to use this code
Use F52.9 when the clinician documents sexual dysfunction and also states it is not due to a substance or known medical cause. It is appropriate when the chart lacks enough detail to assign a more specific sexual dysfunction code. Check documentation if a mental, endocrine, neurologic, or medication-related cause is mentioned.
Do not use for
Do not use this code when the dysfunction is linked to a substance, medication, or an identifiable physiological disorder. It is also not the best choice if the provider documents a more specific sexual dysfunction diagnosis.
Coding tip
Code F52.9 only after confirming the absence of a substance or known physiological cause in the documentation.
