Patient EducationClinical

Gas

Everyone has gas. Most people pass gas 13 to 21 times a day. Passing gas through the mouth is called belching or burping. Passing gas through the anus is called flatulence. Most of the time gas does not have an odor. The odor comes from bacteria in the large intestine that release small amounts of gases that contain sulfur.

Questions About R14.3Overview

Is R14.3 (Flatulence and related conditions) a billable code?

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

What MS-DRG does R14.3 group to?

When flatulence is the principal diagnosis on an inpatient stay, it groups to MS-DRG 391, 392, with relative weights from 0.7796 to 1.2683 depending on complications. Higher weights mean higher Medicare reimbursement.

Can R14.3 be a principal diagnosis?

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

What is the ICD-9 equivalent of R14.3?

Under the General Equivalence Mappings, flatulence converts to ICD-9-CM 787.3 (flatul/eructat/gas pain). 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.
