ICD-10-CM P72.8
CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

P72.8 is a billable ICD-10-CM diagnosis code for other specified transitory neonatal endocrine disorders. 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 28 closely related codes. Coders also document this condition as idiopathic transient neonatal hyperinsulinemia. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Other specified and unspecified perinatal conditions.

From Block P70-P74 Transitory endocrine and metabolic disorders specific to newborn applies to 33 codes
  • transitory endocrine and metabolic disturbances caused by the infant's response to maternal endocrine and metabolic factors, or its adjustment to extrauterine environment
From Chapter 16 (P00-P96) Certain conditions originating in the perinatal period applies to 463 codes
  • conditions that have their origin in the fetal or perinatal period (before birth through the first 28 days after birth) even if morbidity occurs later

Excludes1

Questions About P72.8Overview

What is the ICD-10 code for other specified transitory neonatal endocrine disorders?

The ICD-10-CM code for other specified transitory neonatal endocrine disorders is P72.8 (sometimes written as P728). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is P72.8 (Other transitory neonatal endocrine disorders) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other specified transitory neonatal endocrine disorders on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does P72.8 group to?

When other specified transitory neonatal endocrine disorders 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 P72.8 a CC or MCC?

CMS lists P72.8 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 28 closely related codes in its exclusion list.

Can P72.8 be reported with E07.1?

Not as a rule. The Excludes1 note at P72, which applies to P72.8, lists "dyshormogenetic goiter (E07.1)". 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).
