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

P28.30 is a billable ICD-10-CM diagnosis code for primary sleep apnea of newborn, unspecified. 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 17 closely related codes. Coders also document this condition as neonatal central sleep apnea. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Respiratory perinatal condition.
