About coding Piles
The ICD-10-CM code for Piles is K64.9 (Unspecified hemorrhoids).
Within K64, choose K64.9 (Unspecified hemorrhoids) only when documentation doesn't support a more specific option: first degree hemorrhoids (K64.0), second degree hemorrhoids (K64.1), third degree hemorrhoids (K64.2), fourth degree hemorrhoids (K64.3), residual hemorrhoidal skin tags (K64.4), perianal venous thrombosis (K64.5) and other hemorrhoids (K64.8).
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.
