ICD-10-CM P83.0
CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

P83.0 is a billable ICD-10-CM diagnosis code for sclerema neonatorum. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 794. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 3 closely related codes. Coders also document this condition as fat necrosis of subcutaneous tissue. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Other specified and unspecified perinatal conditions.

Questions About P83.0Overview

What is the ICD-10 code for sclerema neonatorum?

The ICD-10-CM code for sclerema neonatorum is P83.0 (sometimes written as P830). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is P83.0 (Other conditions of integument specific to newborn) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report sclerema neonatorum on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does P83.0 group to?

When sclerema neonatorum is the principal diagnosis on an inpatient stay, it groups to MS-DRG 794 (neonate with Other Significant Problems), which carries a relative weight of 1.4934. Higher weights mean higher Medicare reimbursement.

Is P83.0 a CC or MCC?

CMS lists P83.0 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 3 closely related codes in its exclusion list.

Can P83.0 be reported with a code from P56?

Not as a rule. The Excludes1 note at P83, which applies to P83.0, lists "hydrops fetalis due to hemolytic disease (P56.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
