A02.24Salmonella osteomyelitis

A02.24 is the ICD-10-CM diagnosis code for salmonella osteomyelitis. It belongs to category A02 (other salmonella infections), block A00-A09 (intestinal infectious diseases) 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 A02.2 (localized salmonella infections), A02.24 is specifically for salmonella osteomyelitis. Related codes cover localized salmonella infection, unspecified (A02.20), salmonella meningitis (A02.21), salmonella pneumonia (A02.22), salmonella arthritis (A02.23), salmonella pyelonephritis (A02.25) and salmonella with other localized infection (A02.29).

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 539 (Osteomyelitis with MCC, relative weight 1.9385), DRG 540 (Osteomyelitis with CC, relative weight 1.3079), DRG 541 (Osteomyelitis without CC/MCC, relative weight 0.8297) and 3 more, in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue) and MDC 25 (Human Immunodeficiency Virus Infections), 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 003.24 (salmonella osteomyelitis).
