G: subsequent encounter for fracture with delayed healing
K: subsequent encounter for fracture with nonunion
P: subsequent encounter for fracture with malunion

Risk adjustment

S79.001 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.

S79.001 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
