Other codes that can never be billed with K29.0

K25Gastric ulcer
K92.2Gastrointestinal hemorrhage, unspecified

Risk adjustment

K29.0 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 K29.0

2 child codes. Green means billable.
