P80.9Hypothermia of newborn, unspecified

Billable / specific codeICD-10-CM

P80.9 is a billable, specific ICD-10-CM code for hypothermia of newborn, unspecified. It is valid for submission on a claim.

Risk adjustment

P80.9 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

How P80.9 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to P80.9.
