About P12.4

P12.4 is the ICD-10-CM diagnosis code for injury of scalp of newborn due to monitoring equipment. It belongs to category P12 (birth injury to scalp), block P10-P15 (birth trauma) 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 P12 (birth injury to scalp), P12.4 is specifically for injury of scalp of newborn due to monitoring equipment. Related codes cover Cephalhematoma due to birth injury (P12.0), Chignon (from vacuum extraction) due to birth injury (P12.1), Epicranial subaponeurotic hemorrhage due to birth injury (P12.2), bruising of scalp due to birth injury (P12.3), other birth injuries to scalp (P12.8) and unspecified (P12.9).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 795 (Normal Newborn, relative weight 0.2022), 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 767.19 (other injuries to scalp).
