P83 ICD-10-CM Code: Other conditions of integument specific to newborn

P83 is the ICD-10-CM diagnosis code for other conditions of integument specific to newborn. P83 sits in the ICD-10-CM chapter for certain conditions originating in the perinatal period (p00-p96), within the section covering conditions involving the integument and temperature regulation of newborn (p80-p83).

Header codes like P83 cannot be reported on claims directly, they organize child codes that share clinical context but the actual diagnosis must be coded to the highest level of specificity supported by the documentation. Coders should look at P83's child codes and select the one that matches the patient's documented presentation, since payers reject header codes submitted as the primary diagnosis. For risk adjustment workflows, header codes never contribute to a Medicare Advantage member's RAF score on their own; only billable child codes that happen to map to a payment HCC affect risk-adjusted plan payments.
