ICD-10-CM Codes›P00–P96›P19-P29›P24
- Billable — Valid for Submission
- MCC — Major Complication or Comorbidity
- Not Chronic
P24.01 is a billable ICD-10-CM diagnosis code for meconium aspiration with respiratory symptoms. 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 68 closely related codes. Coders also document this condition as meconium aspiration syndrome. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Respiratory perinatal condition.

Meconium Aspiration Syndrome
a condition caused by inhalation of meconium into the lung of fetus or newborn, usually due to vigorous respiratory movements during difficult parturition or respiratory system abnormalities. meconium aspirate may block small airways leading to difficulties in pulmonary gas exchange and aspiration pneumonia.

Questions About P24.01Overview
What is the ICD-10 code for meconium aspiration with respiratory symptoms?
The ICD-10-CM code for meconium aspiration with respiratory symptoms is P24.01 (sometimes written as P2401). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is P24.01 (Meconium aspiration) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report meconium aspiration with respiratory symptoms on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does P24.01 group to?
When meconium aspiration with respiratory symptoms 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 P24.01 a CC or MCC?
CMS lists P24.01 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 68 closely related codes in its exclusion list.
Can P24.01 be reported with P03.82?
Not as a rule. The Excludes1 note at P24.0, which applies to P24.01, lists "meconium passage (without aspiration) during delivery (P03.82 )". 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).
