K64.8Other hemorrhoids

K64.8 is the ICD-10-CM diagnosis code for other hemorrhoids. It belongs to category K64 (hemorrhoids and perianal venous thrombosis), block K55-K64 (other diseases of intestines) and chapter 11 (diseases of the digestive system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within K64, choose K64.8 (Other 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 unspecified hemorrhoids (K64.9).

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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 455.0 (internal hemorrhoids without mention of complication), 455.1 (internal thrombosed hemorrhoids), 455.2 (internal hemorrhoids with other complication) and 1 more.
