K83.0Cholangitis

Non-billable headerICD-10-CM

K83.0 is a non-billable header ICD-10-CM code for cholangitis. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

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

  • cholangitic liver abscess (K75.0)
  • cholangitis with choledocholithiasis (K80.3-, K80.4-)

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

  • chronic nonsuppurative destructive cholangitis (K74.3)
  • primary biliary cholangitis (K74.3)
  • primary biliary cirrhosis (K74.3)

Excludes1 inherited from the categories above K83.0

These are not written on K83.0, but they bind it: a note on a category applies to every code beneath it. Billing K83.0 with anything listed here is a denial.

Written on K83 Other diseases of biliary tract

  • postcholecystectomy syndrome (K91.5)

Excludes2 inherited from the categories above K83.0

Also inherited, and the opposite of Excludes1: these conditions are not part of K83.0, but a patient can have both, so you may code both.

Written on K83 Other diseases of biliary tract

  • conditions involving the gallbladder (K81-K82)
  • conditions involving the cystic duct (K81-K82)

Other codes that can never be billed with K83.0

These codes carry an Excludes1 note pointing at K83.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K83.0 alone.

Risk adjustment

K83.0 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 history

K83.0 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead K83.0

Questions about K83.0

Is K83.0 a billable ICD-10-CM code?
No. K83.0 is a non-billable header code. Code to a higher level of specificity using one of its child codes.
Where does K83.0 sit in the tabular list?
Diseases of the digestive system (K00-K95), in the block Disorders of gallbladder, biliary tract and pancreas (K80-K87).
What cannot be coded together with K83.0?
K83.0 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above K83.0 (K83) and apply to it just the same.
