About A54.6

A54.6 is the ICD-10-CM diagnosis code for gonococcal infection of anus and rectum. It belongs to category A54 (gonococcal infection), block A50-A64 (infections with a predominantly sexual mode of transmission) and chapter 1 (certain infectious and parasitic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within A54 (gonococcal infection), A54.6 is specifically for gonococcal infection of anus and rectum. Related codes cover of lower genitourinary tract without periurethral or accessory gland abscess (A54.0), of lower genitourinary tract with periurethral and accessory gland abscess (A54.1), gonococcal pelviperitonitis and other gonococcal genitourinary infection (A54.2), of eye (A54.3), of musculoskeletal system (A54.4), gonococcal pharyngitis (A54.5), other gonococcal infections (A54.8) and unspecified (A54.9).

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 098.7 (gonococcal infection of anus and rectum).
