P54.1Neonatal melena

P54.1 is the ICD-10-CM diagnosis code for neonatal melena. It belongs to category P54 (other neonatal hemorrhages), block P50-P61 (hemorrhagic and hematological disorders of newborn) and chapter 16 (certain conditions originating in the perinatal period). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within P54 (other neonatal hemorrhages), P54.1 is specifically for neonatal melena. Related codes cover neonatal hematemesis (P54.0), neonatal rectal hemorrhage (P54.2), other neonatal gastrointestinal hemorrhage (P54.3), neonatal adrenal hemorrhage (P54.4), neonatal cutaneous hemorrhage (P54.5), neonatal vaginal hemorrhage (P54.6), other specified neonatal hemorrhages (P54.8) and neonatal hemorrhage, unspecified (P54.9).

Don't report P54.1 together with the conditions in its Excludes1 note: neonatal melena due to swallowed maternal blood (P78.2).

As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 772.4 (gastrointestinal hemorrhage of fetus or newborn).
