ICD-10 code for musculoskeletal gonococcus

The ICD-10-CM code for musculoskeletal gonococcus is A54.40 (Gonococcal infection of musculoskeletal system, unspecified). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on A54.40.

Within A54.4, choose A54.40 (unspecified) only when documentation doesn't support a more specific option: spondylopathy (A54.41), arthritis (A54.42), osteomyelitis (A54.43) and infection of other musculoskeletal tissue (A54.49).

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 456 (Spinal Fusion Except Cervical with Spinal Curvature, Malignancy, or Infection with MCC, relative weight 7.6244), DRG 457 (Spinal Fusion Except Cervical with Spinal Curvature, Malignancy, or Infection with CC, relative weight 5.3668), DRG 458 (Spinal Fusion Except Cervical with Spinal Curvature, Malignancy, or Infection without CC/MCC, relative weight 4.0388), DRG 548 (Septic Arthritis with MCC, relative weight 1.9519), DRG 549 (Septic Arthritis with CC, relative weight 1.1435) and DRG 550 (Septic Arthritis without CC/MCC, relative weight 0.8591), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
