About coding jejunostomy attention
The ICD-10-CM code for jejunostomy attention is Z43.4 (Encounter for attention to other artificial openings of digestive tract).
Within Z43, choose Z43.4 (other artificial openings of digestive tract) only when documentation doesn't support a more specific option: tracheostomy (Z43.0), gastrostomy (Z43.1), ileostomy (Z43.2), colostomy (Z43.3), cystostomy (Z43.5), other artificial openings of urinary tract (Z43.6), artificial vagina (Z43.7), other artificial openings (Z43.8) and 1 more.
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.
