No. N46.0 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does N46.0 sit in the tabular list?

Diseases of the genitourinary system (N00-N99), in the block Diseases of male genital organs (N40-N53).

Excludes1 inherited from the categories above N46.0

These are not written on N46.0, but they bind it: a note on a category applies to every code beneath it. Billing N46.0 with anything listed here is a denial.

Written on N46 — Male infertility

vasectomy status (Z98.52)

Other codes that can never be billed with N46.0

These codes carry an Excludes1 note pointing at N46.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N46.0 alone.

E29Testicular dysfunction
Z98.5Sterilization status
R86Abnormal findings in specimens from male genital organs

Risk adjustment

N46.0 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code history

N46.0 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead N46.0
