About coding Flatus
The ICD-10-CM code for Flatus is R14.3 (Flatulence). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on R14.3.
Within R14 (Flatulence and related conditions), R14.3 is specifically for Flatulence. Related codes cover abdominal distension (gaseous) (R14.0), gas pain (R14.1) and eructation (R14.2).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 391 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders with MCC, relative weight 1.2392) and DRG 392 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders without MCC, relative weight 0.7645), in MDC 06 (Diseases and Disorders of the Digestive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
