About coding colostomy stenosis
The ICD-10-CM code for colostomy stenosis is K94.03 (Colostomy malfunction).
Within K94.0 (colostomy complications), K94.03 is specifically for colostomy malfunction. Related codes cover colostomy complication, unspecified (K94.00), colostomy hemorrhage (K94.01), colostomy infection (K94.02) and other complications of colostomy (K94.09).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
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.
