A54.85Gonococcal peritonitis

A54.85 is the ICD-10-CM diagnosis code for gonococcal peritonitis. 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 A54.8 (other gonococcal infections), A54.85 is specifically for gonococcal peritonitis. Related codes cover gonococcal meningitis (A54.81), gonococcal brain abscess (A54.82), gonococcal heart infection (A54.83), gonococcal pneumonia (A54.84), gonococcal sepsis (A54.86) and other gonococcal infections (A54.89).

Don't report A54.85 together with the conditions in its Excludes1 note: gonococcal pelviperitonitis (A54.24).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 371 (Major Gastrointestinal Disorders and Peritoneal Infections with MCC, relative weight 1.7089), DRG 372 (Major Gastrointestinal Disorders and Peritoneal Infections with CC, relative weight 0.9964) and DRG 373 (Major Gastrointestinal Disorders and Peritoneal Infections without CC/MCC, relative weight 0.6941), 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 098.86 (gonococcal peritonitis).
