K83.0: Cholangitis

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

A category’s note binds every code beneath it.

Written on K83: Other diseases of biliary tract

  • postcholecystectomy syndrome (K91.5)

Excludes2 inherited from the categories above K83.0

Not part of this code, but both may be coded when both are present.

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

Their own Excludes1 notes name this code, so the conflict is not listed above.
