- Not Chronic
P83.2 is a billable ICD-10-CM diagnosis code for hydrops fetalis not due to hemolytic disease. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 791, 793. As a secondary diagnosis, it counts as a major complication or comorbidity (MCC) and places an inpatient stay in the highest severity level of its MS-DRG family. It does not count, however, when the principal diagnosis is one of 18 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Other specified and unspecified perinatal conditions.

Questions About P83.2Overview
What is the ICD-10 code for hydrops fetalis not due to hemolytic disease?
The ICD-10-CM code for hydrops fetalis not due to hemolytic disease is P83.2 (sometimes written as P832). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is P83.2 (Other conditions of integument specific to newborn) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report hydrops fetalis not due to hemolytic disease on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does P83.2 group to?
When hydrops fetalis not due to hemolytic disease is the principal diagnosis on an inpatient stay, it groups to MS-DRG 793, 791, with relative weights from 4.1073 to 4.2192 depending on complications. Higher weights mean higher Medicare reimbursement.
Is P83.2 a CC or MCC?
CMS lists P83.2 as an MCC (major complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it places the inpatient stay in the highest-weighted DRG of its severity family. It does not count when the principal diagnosis is one of the 18 closely related codes in its exclusion list.
Can P83.2 be reported with a code from P56?
Not as a rule. The Excludes1 note at P83, which applies to P83.2, 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).
