Written on K80 — Cholelithiasis

retained cholelithiasis following cholecystectomy (K91.86)

Other codes that can never be billed with K80.6

These codes carry an Excludes1 note pointing at K80.6. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K80.6 alone.

K81Cholecystitis
K82.0Obstruction of gallbladder
K82.4Cholesterolosis of gallbladder
K83.1Obstruction of bile duct

Risk adjustment

K80.6 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 history

K80.6 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
