CMSSource: CMS FY 2026 ICD-10-CM dataset · Effective Oct 1, 2025 – Sep 30, 2026

P26.9 is a billable ICD-10-CM diagnosis code for unspecified pulmonary hemorrhage 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. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Respiratory perinatal condition.

For Medicare Advantage risk adjustment, P26.9 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.

Patient EducationClinical

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.

Questions About P26.9Overview

What is the ICD-10 code for unspecified pulmonary hemorrhage originating in the perinatal period?

The ICD-10-CM code for unspecified pulmonary hemorrhage originating in the perinatal period is P26.9 (sometimes written as P269). It is billable on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Is P26.9 (Pulmonary hemorrhage originating in the perinatal period) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report unspecified pulmonary hemorrhage originating in the perinatal period on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does P26.9 group to?

When unspecified pulmonary hemorrhage originating in the perinatal period is the principal diagnosis on an inpatient stay, it groups to MS-DRG 791, 793, with relative weights from 4.0590 to 4.1696 depending on complications. Higher weights mean higher Medicare reimbursement.

Is P26.9 a CC or MCC?

CMS lists P26.9 as an MCC (major complication or comorbidity) for FY 2026. 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 78 closely related codes in its exclusion list.

What is the ICD-9 equivalent of P26.9?

Under the General Equivalence Mappings, unspecified pulmonary hemorrhage originating in the perinatal period converts to ICD-9-CM 770.3 (NB pulmonary hemorrhage). The mapping is approximate, so confirm the match fits the documentation.

What HCC is P26.9?

P26.9 (unspecified pulmonary hemorrhage originating in the perinatal period) maps to CMS-HCC Category 213 (Cardio-Respiratory Failure and Shock), commonly written as HCC 213, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2026. It does not map to any RxHCC in the Part D prescription drug model.

Does P26.9 risk-adjust for Medicare Advantage payment?

Yes. When documented and reported on a Medicare Advantage encounter, P26.9 adds a risk adjustment factor of about 0.370 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.258 to 0.662 depending on the payment segment). A more severe related category (HCC 211 and HCC 212) supersedes it when both are reported. See the full factor table on the HCC 213 category page.
