Questions About R04.1Overview

Is R04.1 (Hemorrhage from respiratory passages) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report hemorrhage from throat on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does R04.1 group to?

When hemorrhage from throat is the principal diagnosis on an inpatient stay, it groups to MS-DRG 154, 155, 156, with relative weights from 0.6911 to 1.5635 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R04.1 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the hemorrhage from throat is established, that condition takes the principal position instead.

What is the ICD-9 equivalent of R04.1?

Under the General Equivalence Mappings, hemorrhage from throat converts to ICD-9-CM 784.8 (hemorrhage from throat). The mapping is a direct match.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
