ICD-10 Code A54.43 – Gonococcal Osteomyelitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A54.43 – Gonococcal osteomyelitis
What it is
A54.43 identifies osteomyelitis caused by Neisseria gonorrhoeae, a gonococcal infection involving bone. Use it when the record clearly links the bone infection to gonorrhea.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include localized bone pain, tenderness, swelling, and evidence of gonococcal infection elsewhere or by microbiologic confirmation.
When to use this code
Use this code when the provider documents gonococcal osteomyelitis or states that gonorrhea is the cause of the bone infection. It may also apply when the chart clearly supports a gonococcal etiology for osteomyelitis. Check documentation if the organism is not specified.
Do not use for
Do not use this code for osteomyelitis from other bacteria, trauma, or noninfectious bone disease. If gonococcal involvement is not documented, choose the more specific documented diagnosis.
Coding tip
Confirm that the organism and the bone infection are both documented before assigning A54.43.
