About coding Pectenosis
The ICD-10-CM code for Pectenosis is K62.4 (Stenosis of anus and rectum).
Within K62 (other diseases of anus and rectum), K62.4 is specifically for stenosis of anus and rectum. Related codes cover anal polyp (K62.0), rectal polyp (K62.1), anal prolapse (K62.2), rectal prolapse (K62.3), hemorrhage of anus and rectum (K62.5), ulcer of anus and rectum (K62.6), radiation proctitis (K62.7), other specified diseases of anus and rectum (K62.8) 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.
