N46.024Azoospermia due to radiation

N46.024 is the ICD-10-CM diagnosis code for azoospermia due to radiation. It belongs to category N46 (male infertility), block N40-N53 (diseases of male genital organs) and chapter 14 (diseases of the genitourinary system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within N46.02 (azoospermia due to extratesticular causes), N46.024 is specifically for azoospermia due to radiation. Related codes cover drug therapy (N46.021), infection (N46.022), obstruction of efferent ducts (N46.023), systemic disease (N46.025) and other extratesticular causes (N46.029).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 729 (Other Male Reproductive System Diagnoses with CC/MCC, relative weight 1.0544) and DRG 730 (Other Male Reproductive System Diagnoses without CC/MCC, relative weight 0.6597), in MDC 12 (Diseases and Disorders of the Male Reproductive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

The Medicare Code Editor expects this diagnosis only for patients age 15 through 124.

It is on the CMS list of diagnoses consistent only with male patients (the sex-conflict edit itself was retired in FY2025).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 606.0 (azoospermia).
