Billable / SpecificICD-10-CMOfficial ICD-10-CMCodebook guidanceOther 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.
Buddy Insight
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.

Common Mistakes
Last updated: FY2026 ICD-10-CM Apr update, Apr 1, 2026 through Sep 30, 2026. CMS-HCC V28 is 100% phased in for payment year 2026.
Is G95.89 an HCC code?
Yes. G95.89 maps to Spinal Cord Disorders/Injuries under the CMS-HCC V28 risk adjustment model (and Spinal Cord Disorders/Injuries 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 G95.89
For G95.89to 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 G95.89 during that encounter, not just copy-forwarded from a problem list.
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 community, non-dual, aged base RAF weight of 0.282. Under the older V24 model, G95.89 mapped to the same category but with a base RAF weight of 0.464, 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.
Use this code only when the specific spinal cord disease is documented but doesn't match other G95 codes. Because G95.89 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 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
