Written on S83.2 — Tear of meniscus, current injury

old bucket-handle tear (M23.2)

Excludes2 inherited from the categories above S83.209

Also inherited, and the opposite of Excludes1: these conditions are not part of S83.209, but a patient can have both, so you may code both.

Written on S83 — Dislocation and sprain of joints and ligaments of knee

derangement of patella (M22.0-M22.3)
injury of patellar ligament (tendon) (S76.1-)
internal derangement of knee (M23.-)

recurrent dislocation of knee (M22.0)

Risk adjustment

S83.209 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.

How S83.209 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to S83.209.
