ICD-10 Code A54.4: Gonococcal infection of musculoskeletal system
Reviewed by HealthAssure Clinical TeamUpdated 26 May 2026
What is this code?
ICD-10 entries help standardize how diagnoses are organized for coding, reporting, analytics, and documentation. This code sits within the broader ICD-10 area for Certain infectious and parasitic diseases (A00-B99).
đź“‹Clinical overview
This ICD-10 code is commonly used when documentation describes gonococcal infection. The most accurate code depends on whether the documented gonococcal disease involves the lower or upper genitourinary tract, eye, musculoskeletal tissue, anus or rectum, heart, bloodstream, or another specified site.
When is it used?
- May be used when a clinician documents gonococcal infection of musculoskeletal system in a patient's medical record.
- May appear in hospital records, claims, referrals, and clinical documentation.
- This code may act more like a grouping or parent code, so a more specific child code may be used in final documentation when available.
What it does not mean
- A code alone does not explain severity, treatment plan, or outcome.
- A medical code should not be treated as a substitute for a doctor's diagnosis or advice.
- This entry may represent a broader category rather than the most specific billable code.
đź©şClinical context
When commonly used
- Primary-care, urgent-care, emergency, infectious-disease, sexual-health, and follow-up documentation where gonococcal infection affects diagnosis, treatment planning, or partner-management counseling.
- Coding and utilization-review workflows where the chart identifies the exact gonococcal disease site or a more invasive manifestation such as cardiac involvement or sepsis.
Common management context
- Gonococcal infection follow-up often includes symptom review, specimen testing context, antimicrobial treatment planning, partner-management counseling, and screening for coinfections or complications.
- Documentation usually becomes more specific when the chart identifies the exact anatomic site, localized versus disseminated disease, abscess formation, ocular or musculoskeletal involvement, or systemic infection.
- Specialist context already linked on this page includes Infectious Disease Specialist, General Physician.
🔍Key distinctions
Important notes
- This ICD-10 family captures gonococcal infection across multiple anatomic sites, and the documented site or invasive manifestation is what usually drives final code specificity.
- Localized genitourinary disease, ocular disease, musculoskeletal disease, anorectal disease, cardiac involvement, sepsis, and unspecified gonococcal infection are coded separately from one another when the chart names the manifestation more clearly.
- Documentation that describes gonococcal infection is coded differently from chlamydial infection, nongonococcal urethritis, or other sexually transmitted infections when the organism or site is documented more clearly.
