Excludes2 inherited from the categories above M19.29

Also inherited, and the opposite of Excludes1: these conditions are not part of M19.29, but a patient can have both, so you may code both.

arthrosis of spine (M47.-)
hallux rigidus (M20.2)
osteoarthritis of spine (M47.-)

Risk adjustment

M19.29 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.
