K: subsequent encounter for fracture with nonunion
P: subsequent encounter for fracture with malunion

Excludes1 inherited from the categories above S52.522D

These are not written on S52.522D, but they bind it: a note on a category applies to every code beneath it. Billing S52.522D with anything listed here is a denial.

Written on S52 — Fracture of forearm

traumatic amputation of forearm (S58.-)

Excludes2 inherited from the categories above S52.522D

Also inherited, and the opposite of Excludes1: these conditions are not part of S52.522D, but a patient can have both, so you may code both.

Written on S52.5 — Fracture of lower end of radius

physeal fractures of lower end of radius (S59.2-)

Written on S52 — Fracture of forearm

fracture at wrist and hand level (S62.-)
periprosthetic fracture around internal prosthetic elbow joint (M97.4)

Other codes that can never be billed with S52.522D

These codes carry an Excludes1 note pointing at S52.522D. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S52.522D alone.

M84.3Stress fracture
M84.4Pathological fracture, not elsewhere classified
S51Open wound of elbow and forearm

Risk adjustment

S52.522D 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.

Medicare coverage

S52.522D is named in 3 Medicare coverage policies — 3 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
