About coding colostomy stoma complication
The ICD-10-CM code for colostomy stoma complication is K94.00 (Colostomy complication, unspecified). The official index lists 5 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K94.00.
Within K94.0, choose K94.00 (Colostomy complication, unspecified) only when documentation doesn't support a more specific option: colostomy hemorrhage (K94.01), colostomy infection (K94.02), colostomy malfunction (K94.03) and other complications of colostomy (K94.09).
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 393 (Other Digestive System Diagnoses with MCC, relative weight 1.5881), DRG 394 (Other Digestive System Diagnoses with CC, relative weight 0.9228) and DRG 395 (Other Digestive System Diagnoses without CC/MCC, relative weight 0.6382), 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.
