G95.20
BillableUnspecified cord compression
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is G95.20 an HCC code?
Yes. G95.20 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 G95.20
For G95.20to 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 G95.20 during that encounter — not just copy-forwarded from a problem list.
What This Code Means
G95.20 is the ICD-10-CM diagnosis code for unspecified cord compression. This code describes pressure or squeezing of the spinal cord when the specific cause is not identified or documented. The compression can result from various conditions affecting the spine and may cause pain, weakness, or numbness. G95.20 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, G95.20 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, G95.20 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 documentation does not specify the cause of cord compression; if a cause is identified (such as stenosis, tumor, or herniated disc), use the more specific code instead. Because G95.20 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 G95.20 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 documentation does not specify the cause of cord compression; if a cause is identified (such as stenosis, tumor, or herniated disc), use the more specific code instead
- •Review imaging reports and clinical notes carefully to determine if a more specific etiology code (G95.21, G95.29) should be used rather than the unspecified code
Clinical Significance
Unspecified cord compression represents compression of the spinal cord from an unspecified cause, which can result from herniated discs, tumors, abscesses, hematomas, or other space-occupying lesions within the spinal canal. Cord compression is a neurological emergency when acute, as delayed treatment can lead to permanent paralysis. This code captures the clinical urgency while noting that the specific cause may not yet be determined.
Documentation Requirements
- ✓Imaging (MRI preferred) demonstrating spinal cord compression
- ✓Neurological examination documenting myelopathic signs (upper motor neuron signs, sensory level, bowel/bladder dysfunction)
- ✓Level of spinal cord compression documented
- ✓Acuity of presentation (acute, subacute, or chronic)
- ✓Any identified cause should be coded separately; if cause is known, query whether a more specific code applies
Commonly Confused Codes
- •G95.29 — Other cord compression: use when the cause is specified but does not have its own dedicated code
- •M47.10 — Other spondylosis with myelopathy, site unspecified: when degenerative spine disease causes cord compression
- •G95.0 — Syringomyelia: internal cord cavity, not external compression
- •M50.00 — Cervical disc disorder with myelopathy, unspecified cervical region: when cervical disc herniation causes cord compression
