About P81

P81 is the ICD-10-CM diagnosis code for other disturbances of temperature regulation of newborn. It belongs to block P80-P83 (conditions involving the integument and temperature regulation 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: P81.0 (newborn), P81.8 (newborn) and P81.9 (unspecified).

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