Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

enlarged lymph nodes (R59.-)
localized adiposity (E65)
swelling of joint (M25.4-)

Includes

Conditions this code covers.

subcutaneous nodules (localized)(superficial)

Risk adjustment

R22 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 R22

6 child codes. Green means billable.
