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 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 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 2027.

- 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
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

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 P26.8Overview
What is the ICD-10 code for other pulmonary hemorrhages originating in the perinatal period?
The ICD-10-CM code for other pulmonary hemorrhages originating in the perinatal period is P26.8 (sometimes written as P268). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is P26.8 (Pulmonary hemorrhage originating in the perinatal period) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other pulmonary hemorrhages originating in the perinatal period on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does P26.8 group to?
When other pulmonary hemorrhages originating in the perinatal period 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 P26.8 a CC or MCC?
CMS lists P26.8 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 78 closely related codes in its exclusion list.
Can P26.8 be reported with R04.81?
Not as a rule. The Excludes1 note at P26, which applies to P26.8, lists "acute idiopathic hemorrhage in infants over 28 days old (R04.81)". 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).
What HCC is P26.8?
P26.8 (other pulmonary hemorrhages 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 2027. It does not map to any RxHCC in the Part D prescription drug model.
Does P26.8 risk-adjust for Medicare Advantage payment?
Yes. When documented and reported on a Medicare Advantage encounter, P26.8 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.
