The ICD-10-CM code for ulcer of esophagus without bleeding is K22.10 (sometimes written as K2210). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is K22.10 (Ulcer of esophagus) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report ulcer of esophagus without bleeding on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does K22.10 group to?
When ulcer of esophagus without bleeding is the principal diagnosis on an inpatient stay, it groups to MS-DRG 381, 380, 382, with relative weights from 0.7283 to 1.9243 depending on complications. Higher weights mean higher Medicare reimbursement.
Is K22.10 a CC or MCC?
CMS lists K22.10 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 4 closely related codes in its exclusion list.
Can K22.10 be reported with a code from K22.7?
Not as a rule. The Excludes1 note at K22.1, which applies to K22.10, lists "Barrett's esophagus (K22.7-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
