About coding Gonococcus
The ICD-10-CM code for Gonococcus is A54.9 (Gonococcal infection, unspecified). The official index lists 37 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on A54.9.
Within A54, choose A54.9 (unspecified) only when documentation doesn't support a more specific option: 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), of anus and rectum (A54.6) and other gonococcal infections (A54.8).
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 867 (Other Infectious and Parasitic Diseases Diagnoses with MCC, relative weight 2.1859), DRG 868 (Other Infectious and Parasitic Diseases Diagnoses with CC, relative weight 1.0235) and DRG 869 (Other Infectious and Parasitic Diseases Diagnoses without CC/MCC, relative weight 0.6787), in MDC 18 (Infectious and Parasitic Diseases, Systemic or Unspecified Sites), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
