Written on S43.42 Sprain of rotator cuff capsule

  • rotator cuff syndrome (complete) (incomplete), not specified as traumatic (M75.1-)

Excludes2 inherited from the categories above S43.422S

Also inherited, and the opposite of Excludes1: these conditions are not part of S43.422S, but a patient can have both, so you may code both.

Written on S43.42 Sprain of rotator cuff capsule

  • injury of tendon of rotator cuff (S46.0-)

Written on S43 Dislocation and sprain of joints and ligaments of shoulder girdle

  • strain of muscle, fascia and tendon of shoulder and upper arm (S46.-)

Risk adjustment

S43.422S 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.
