2027 ICD-10-CM Diagnosis Code P54.3Other neonatal gastrointestinal hemorrhage
ICD-10-CM Codes›P00–P96›P50-P61›P54
- Billable — Valid for Submission
- MCC — Major Complication or Comorbidity
- Not Chronic
P54.3 is a billable ICD-10-CM diagnosis code for other neonatal gastrointestinal hemorrhage. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 791, 793. As a secondary diagnosis, it counts as a major complication or comorbidity (MCC) and places an inpatient stay in the highest severity level of its MS-DRG family. It does not count, however, when the principal diagnosis is one of 44 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Hemorrhagic and hematologic disorders of newborn.

Gastrointestinal Bleeding
Your digestive or gastrointestinal (GI) tract includes the esophagus, stomach, small intestine, large intestine or colon, rectum, and anus. Bleeding can come from any of these areas. The amount of bleeding can be so small that only a lab test can find it.

Questions About P54.3Overview
What is the ICD-10 code for other neonatal gastrointestinal hemorrhage?
The ICD-10-CM code for other neonatal gastrointestinal hemorrhage is P54.3 (sometimes written as P543). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is P54.3 (Other neonatal hemorrhages) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other neonatal gastrointestinal hemorrhage on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does P54.3 group to?
When other neonatal gastrointestinal hemorrhage is the principal diagnosis on an inpatient stay, it groups to MS-DRG 793, 791, with relative weights from 4.1073 to 4.2192 depending on complications. Higher weights mean higher Medicare reimbursement.
Is P54.3 a CC or MCC?
CMS lists P54.3 as an MCC (major complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it places the inpatient stay in the highest-weighted DRG of its severity family. It does not count when the principal diagnosis is one of the 44 closely related codes in its exclusion list.
Can P54.3 be reported with a code from P50?
Not as a rule. The Excludes1 note at P54, which applies to P54.3, lists "newborn affected by (intrauterine) blood loss (P50.-)". 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).
