Z31.4 — Encounter for procreative investigation and testing

Non-billable headerICD-10-CM

Other codes that can never be billed with Z31.4

Z31.4 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.

Z31.4 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
