About P80.8
P80.8 is the ICD-10-CM diagnosis code for other hypothermia of newborn. It belongs to category P80 (hypothermia of newborn), block P80-P83 (conditions involving the integument and temperature regulation 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 P80, choose P80.8 (Other hypothermia of newborn) only when documentation doesn't support a more specific option: cold injury syndrome (P80.0) and unspecified (P80.9).
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 794 (Neonate with Other Significant Problems, relative weight 1.4935), 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 778.3 (other hypothermia of newborn).
