About coding gas excess
The ICD-10-CM code for gas excess is R14.0 (Abdominal distension (gaseous)).
Within R14 (Flatulence and related conditions), R14.0 is specifically for abdominal distension (gaseous). Related codes cover gas pain (R14.1), eructation (R14.2) and Flatulence (R14.3).
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.
