- Billable — Valid for Submission
- CC — Complication or Comorbidity
- Not Chronic
P38.9 is a billable ICD-10-CM diagnosis code for omphalitis without hemorrhage. 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 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 5 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Perinatal infections.

Questions About P38.9Overview
What is the ICD-10 code for omphalitis without hemorrhage?
The ICD-10-CM code for omphalitis without hemorrhage is P38.9 (sometimes written as P389). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is P38.9 (Omphalitis of newborn) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report omphalitis without hemorrhage on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does P38.9 group to?
When omphalitis without hemorrhage 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 P38.9 a CC or MCC?
CMS lists P38.9 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 5 closely related codes in its exclusion list.
Can P38.9 be reported with L08.82?
Not as a rule. The Excludes1 note at P38, which applies to P38.9, lists "omphalitis not of newborn (L08.82)". 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).
