causalgia, upper limb (G56.4-)
central pain syndrome (G89.0)
chronic pain syndrome (G89.4)

G89.2 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.

Code to one of these instead G89.2

4 child codes. Green means billable.
