K25 — Gastric ulcer

Non-billable headerICD-10-CM

K25 is a non-billable header ICD-10-CM code for gastric ulcer. 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.

acute gastritis (K29.0-)
peptic ulcer NOS (K27.-)

Use additional code

Add a secondary code to capture the detail described below.

code to identify:
alcohol abuse and dependence (F10.-)

Includes

Conditions this code covers.

erosion (acute) of stomach
pylorus ulcer (peptic)
stomach ulcer (peptic)

Other codes that can never be billed with K25

These codes carry an Excludes1 note pointing at K25. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K25 alone.

K29.0Acute gastritis
K92.2Gastrointestinal hemorrhage, unspecified

Risk adjustment

K25 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 K25

9 child codes. Green means billable.
