About P80.0

P80.0 is the ICD-10-CM diagnosis code for cold injury syndrome. 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 (hypothermia of newborn), P80.0 is specifically for cold injury syndrome. Related codes cover other hypothermia of newborn (P80.8) and unspecified (P80.9).

Don't report P80.0 together with the conditions in its Excludes1 note: mild hypothermia of newborn (P80.8).

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 778.2 (cold injury syndrome of newborn).
