superficial bite of elbow (S50.36, S50.37)

Written on S51 — Open wound of elbow and forearm

open fracture of elbow and forearm (S52.- with open fracture 7th character)
traumatic amputation of elbow and forearm (S58.-)

Excludes2 inherited from the categories above S51.052

Written on S51 — Open wound of elbow and forearm

open wound of wrist and hand (S61.-)

Risk adjustment

S51.052 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.
