Is G95.89 an HCC code?
Yes. G95.89 (Other specified diseases of spinal cord) maps to HCC 182, Spinal Cord Disorders/Injuries under the CMS-HCC V28 risk adjustment model, with a source-labeled community non-dual aged reference coefficient of 0.478. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes. It is billable for payment year 2026.
Coder answer: G95.89 is billable and maps to V28 HCC 182, Spinal Cord Disorders/Injuries. Open it in the Code Book for the tabular path, RAF, and MEAT checklist.

HCC Category Mapping
These are source-labeled model coefficients, not member totals. A category may still be removed by hierarchy or model cleanup rules. Weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. Actual per-patient RAF contribution depends on member context, hierarchy and cleanup rules, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains available for historical review.

MEAT review for G95.89
For G95.89, confirm that the documentation supports the diagnosis and meets the applicable coding, encounter, program and payer requirements. MEAT (Monitor, Evaluate, Assess, or Treat) is a review mnemonic, not a universal CMS coding rule.
- 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

What This Code Means
G95.89 is the ICD-10-CM diagnosis code for other specified diseases of spinal cord. A specified disease or disorder of the spinal cord that doesn't fit into other defined categories, such as syringomyelia, cord atrophy, or other documented spinal cord conditions. G95.89 sits in the ICD-10-CM chapter for diseases of the nervous system (g00-g99), within the section covering other disorders of the nervous system (g89-g99).
Under the CMS-HCC V28 risk adjustment model, G95.89 maps to Spinal Cord Disorders/Injuries (HCC 182) with a source-labeled community, non-dual, aged reference coefficient of 0.478. For CY2026 non-PACE Medicare Advantage, CMS uses 100% of the 2024 CMS-HCC model (V28). PACE uses a separate model blend. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes.
Use this code only when the specific spinal cord disease is documented but doesn't match other G95 codes. For G95.89, confirm that the documentation supports the diagnosis and meets the applicable coding, encounter, program and payer requirements. MEAT (Monitor, Evaluate, Assess, or Treat) is a review mnemonic, not a universal CMS coding rule. 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, source-labeled coefficient references, and MEAT documentation criteria for G95.89 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code only when the specific spinal cord disease is documented but doesn't match other G95 codes
- •Always review the clinical documentation to ensure a more specific code isn't available before assigning this code
Clinical Significance
Other specified diseases of spinal cord captures a range of specified spinal cord pathologies that do not have their own individual ICD-10-CM codes, including conditions such as drug-induced myelopathy, radiation myelopathy, or other identified cord diseases. This code provides more specificity than unspecified cord disease while acknowledging that not every cord condition has a unique code. Documentation of the specific condition is essential for clinical accuracy.
Documentation Requirements
- ✓Specification of the particular spinal cord disease that qualifies as 'other specified'
- ✓Imaging demonstrating spinal cord pathology
- ✓Neurological examination findings documenting cord-level dysfunction
- ✓Identification of etiology when known (radiation, toxic, drug-induced, etc.)
- ✓Functional impact assessment and management plan
Excludes 1, Do NOT code together
- myelopathy NOS (G95.9)
Commonly Confused Codes
- •G95.9: Disease of spinal cord, unspecified: use only when no further specification is available
- •G95.0: Syringomyelia: has its own specific code and should not be coded as G95.89
- •G95.81: Conus medullaris syndrome: has its own specific code
- •G99.2: Myelopathy in diseases classified elsewhere: use when myelopathy is a manifestation of a classified underlying disease
