Patient EducationClinical

Cough

Coughing is a reflex that keeps your throat and airways clear. Although it can be annoying, coughing helps your body heal or protect itself. Coughs can be either acute or chronic. Acute coughs begin suddenly and usually last no more than 2 to 3 weeks. Acute coughs are the kind you most often get with a cold, flu, or acute bronchitis.

Questions About R04.2Overview

Is R04.2 (Hemorrhage from respiratory passages) a billable code?

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

Can R04.2 be a principal diagnosis?

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

What is the ICD-9 equivalent of R04.2?

Under the General Equivalence Mappings, hemoptysis converts to ICD-9-CM 786.30 (hemoptysis NOS). The mapping is approximate, so confirm the match fits the documentation.

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.
