P26.8 is a billable ICD-10-CM diagnosis code for other pulmonary hemorrhages originating in the perinatal period. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) 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 78 closely related codes. Coders also document this condition as acute idiopathic neonatal pulmonary hemorrhage. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Respiratory perinatal condition.
For Medicare Advantage risk adjustment, P26.8 maps to CMS-HCC Category 213 (Cardio-Respiratory Failure and Shock) under the V28 model, adding a risk factor of about 0.370 for a community, non-dual, aged beneficiary in payment year 2026.

Lung Diseases
When you breathe, your lungs take in oxygen from the air and deliver it to the bloodstream. The cells in your body need oxygen to work and grow. During a normal day, you breathe nearly 25,000 times. People with lung disease have difficulty breathing. Millions of people in the U.S. have lung disease.
