About coding abdominal murmur
The ICD-10-CM code for abdominal murmur is R19.15 (Other abnormal bowel sounds).
Within R19.1, choose R19.15 (Other abnormal bowel sounds) only when documentation doesn't support a more specific option: absent bowel sounds (R19.11) and hyperactive bowel sounds (R19.12).
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.
