K22 — Other diseases of esophagus
Non-billable headerICD-10-CM
K22 is a non-billable header ICD-10-CM code for other diseases of esophagus. It cannot be billed on its own: choose one of the more specific child codes below.
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.
- esophageal varices (I85.-)
Other codes that can never be billed with K22
These codes carry an Excludes1 note pointing at K22. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K22 alone.
Risk adjustment
K22 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.
