Non-billable headerICD-10-CM

K83 is a non-billable header ICD-10-CM code for other diseases of biliary tract. 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.

postcholecystectomy syndrome (K91.5)

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.

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

Other codes that can never be billed with K83

These codes carry an Excludes1 note pointing at K83. 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 alone.

K75.0Abscess of liver

Risk adjustment

K83 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 K83

8 child codes. Green means billable.
