K29 — Gastritis and duodenitis

Non-billable headerICD-10-CM

K29 is a non-billable header ICD-10-CM code for gastritis and duodenitis. 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.

eosinophilic gastritis or gastroenteritis (K52.81)
Zollinger-Ellison syndrome (E16.4)

Other codes that can never be billed with K29

These codes carry an Excludes1 note pointing at K29. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K29 alone.

R58Hemorrhage, not elsewhere classified
K25Gastric ulcer
K92.2Gastrointestinal hemorrhage, unspecified

Risk adjustment

K29 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 K29

9 child codes. Green means billable.
