A54.41
BillableGonococcal spondylopathy
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is A54.41 an HCC code?
Yes. A54.41 maps to Bone/Joint/Muscle Infections/Necrosis under the CMS-HCC V28 risk adjustment model (and Bone/Joint/Muscle Infections/Necrosis under V24).
HCC Category Mapping
RAF weights shown are the community, non-dual, aged base weights from the CMS risk adjustment model file. Actual per-patient RAF contribution depends on member segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.
MEAT Criteria for A54.41
For A54.41 to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically — it has to be re-documented and supported each calendar year.
- MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
- EEvaluate: test results, medication response, or physical findings reviewed by the provider
- AAssess: explicit mention in the assessment or plan with acknowledgment of status
- TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis
Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed A54.41 during that encounter — not just copy-forwarded from a problem list.
What This Code Means
A54.41 is the ICD-10-CM diagnosis code for gonococcal spondylopathy. This is a joint and spine infection caused by gonorrhea bacteria that has spread from the genital area to the backbone and surrounding tissues. It causes inflammation, pain, and potential damage to the spine if left untreated. A54.41 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering infections with a predominantly sexual mode of transmission (a50-a64).
Under the CMS-HCC V28 risk adjustment model, A54.41 maps to Bone/Joint/Muscle Infections/Necrosis (HCC 92) with a community, non-dual, aged base RAF weight of 0.209. Under the older V24 model, A54.41 mapped to the same category but with a base RAF weight of 0.482 — V28 recalibrated weights across the entire model. V28 is the CMS-HCC risk adjustment model that reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition.
This code requires documentation of both the gonococcal infection and the specific spinal/joint involvement; verify the provider has documented the connection between the gonorrhea diagnosis and the spondylopathy. Because A54.41 maps to a payment HCC, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's Medicare Advantage risk adjustment score. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for A54.41 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This code requires documentation of both the gonococcal infection and the specific spinal/joint involvement; verify the provider has documented the connection between the gonorrhea diagnosis and the spondylopathy
- •Ensure this code is not used in combination with other gonococcal codes for different body sites without proper documentation; this is a disseminated gonococcal infection requiring systemic antibiotic treatment
Clinical Significance
Gonococcal spondylopathy is a rare but serious spinal infection from disseminated gonorrhea that can lead to vertebral destruction and neurological complications if untreated. Accurate capture reflects the severity of systemic gonococcal disease involving the spine, which requires prolonged antimicrobial therapy.
Documentation Requirements
- ✓Confirmed Neisseria gonorrhoeae organism identification (culture, PCR, or NAAT)
- ✓Spinal involvement documented with imaging findings (MRI or CT showing vertebral/disc involvement)
- ✓Specific spinal level affected (cervical, thoracic, lumbar, sacral)
- ✓Neurological status assessment (presence or absence of cord compression, radiculopathy)
- ✓Documentation of disseminated gonococcal infection history
Commonly Confused Codes
- •M46.20 (Osteomyelitis of vertebra, unspecified site) — Non-gonococcal vertebral osteomyelitis; the causative organism must be confirmed as gonococcal for A54.41
- •A54.42 (Gonococcal arthritis) — Joint involvement rather than spinal involvement; spondylopathy specifically affects the spine
- •A54.40 (Gonococcal infection of musculoskeletal system, unspecified) — Use A54.41 when the spine is the documented site rather than the unspecified code
