ICD-10 Code E34.52 – Partial androgen insensitivity syndrome (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E34.52 – Partial androgen insensitivity syndrome
What it is
Partial androgen insensitivity syndrome is a condition in which the body does not respond fully to androgens, the hormones that drive male sexual development. It can lead to atypical development of external genitalia and variable sex characteristics.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include ambiguous or undervirilized genitalia, hypospadias, or incomplete masculinization in a person with a 46,XY karyotype.
When to use this code
Use E34.52 when the provider documents partial androgen insensitivity syndrome or partial androgen resistance. Code it for confirmed congenital androgen receptor resistance affecting sexual development, not for nonspecific genital anomalies without that diagnosis.
Do not use for
Do not use this code for complete androgen insensitivity syndrome or other intersex conditions unless documentation specifically states partial androgen insensitivity. If the diagnosis is unclear, check documentation.
Coding tip
Assign the code only when the record explicitly links the clinical findings to partial androgen insensitivity syndrome.
