P26Pulmonary hemorrhage originating in the perinatal period

P26 is the ICD-10-CM diagnosis code for pulmonary hemorrhage originating in the perinatal period. It belongs to block P19-P29 (respiratory and cardiovascular disorders specific to the perinatal period) 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 4 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: P26.0 (period), P26.1 (period), P26.8 (period) and P26.9 (period).

Don't report P26 together with the conditions in its Excludes1 note: acute idiopathic hemorrhage in infants over 28 days old (R04.81).

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