K82.A — Disorders of gallbladder in diseases classified elsewhere
K82.A is a non-billable header ICD-10-CM code for disorders of gallbladder in diseases classified elsewhere. It cannot be billed on its own: choose one of the more specific child codes below.
Code first
The underlying condition must be sequenced before this code.
Excludes1 inherited from the categories above K82.A
These are not written on K82.A, but they bind it: a note on a category applies to every code beneath it. Billing K82.A with anything listed here is a denial.
Other codes that can never be billed with K82.A
These codes carry an Excludes1 note pointing at K82.A. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K82.A alone.

Risk adjustment
K82.A 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
K82.A has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Questions about K82.A
- Is K82.A a billable ICD-10-CM code?
- No. K82.A is a non-billable header code. Code to a higher level of specificity using one of its child codes.
- Where does K82.A 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 K82.A?
