Excludes1 inherited from the categories above S53.20XS

These are not written on S53.20XS, but they bind it: a note on a category applies to every code beneath it. Billing S53.20XS with anything listed here is a denial.

Written on S53.2 Traumatic rupture of radial collateral ligament

  • sprain of radial collateral ligament NOS (S53.43-)

Excludes2 inherited from the categories above S53.20XS

Also inherited, and the opposite of Excludes1: these conditions are not part of S53.20XS, but a patient can have both, so you may code both.

Written on S53 Dislocation and sprain of joints and ligaments of elbow

  • strain of muscle, fascia and tendon at forearm level (S56.-)

Risk adjustment

S53.20XS 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

S53.20XS is named in 1 Medicare coverage policy 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
