About P51

P51 is the ICD-10-CM diagnosis code for umbilical hemorrhage of newborn. It belongs to block P50-P61 (hemorrhagic and hematological disorders of newborn) and chapter 16 (certain conditions originating in the perinatal period). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: P51.0 (newborn), P51.8 (newborn) and P51.9 (unspecified).

Don't report P51 together with the conditions in its Excludes1 note: omphalitis with mild hemorrhage (P38.1) and umbilical hemorrhage from cut end of co-twins cord (P50.5).

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