- Chronic Condition
G95.29 is a billable ICD-10-CM diagnosis code for other cord compression. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 91 through 93, 974 through 976. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 159 closely related codes. Coders also document this condition as compression of spinal cord due to cavernous hemangioma. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Other nervous system disorders (neither hereditary nor degenerative).
For Medicare Advantage risk adjustment, G95.29 maps to CMS-HCC Category 182 (Spinal Cord Disorders/Injuries) under the V28 model, adding a risk factor of about 0.478 for a community, non-dual, aged beneficiary in payment year 2027.

Spinal Cord Diseases
Your spinal cord is a bundle of nerves that runs down the middle of your back. It carries signals back and forth between your body and your brain. It is protected by your vertebrae, which are the bone disks that make up your spine.

Questions About G95.29Overview
What is the ICD-10 code for other cord compression?
The ICD-10-CM code for other cord compression is G95.29 (sometimes written as G9529). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is G95.29 (Other and unspecified cord compression) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other cord compression on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does G95.29 group to?
When other cord compression is the principal diagnosis on an inpatient stay, it groups to MS-DRG 974, 976, 975, 91, 92, 93, with relative weights from 0.7783 to 3.0488 depending on complications. Higher weights mean higher Medicare reimbursement.
Is G95.29 a CC or MCC?
CMS lists G95.29 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 159 closely related codes in its exclusion list.
What is the ICD-9 equivalent of G95.29?
Under the General Equivalence Mappings, other cord compression converts to ICD-9-CM 336.9 (spinal cord disease NOS). The mapping is approximate, so confirm the match fits the documentation.
What HCC is G95.29?
G95.29 (other cord compression) maps to CMS-HCC Category 182 (Spinal Cord Disorders/Injuries), commonly written as HCC 182, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2027. It mapped to HCC 72 under the retired V24 model. It also maps in the PACE (CMS-HCC V22), ESRD (V21), and ESRD (V24) models. In the Part D prescription drug model it maps to RxHCC 155.
Does G95.29 risk-adjust for Medicare Advantage payment?
Yes. When documented and reported on a Medicare Advantage encounter, G95.29 adds a risk adjustment factor of about 0.478 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.270 to 0.478 depending on the payment segment). A more severe related category (HCC 180, HCC 181, HCC 191, and HCC 192) supersedes it when both are reported. See the full factor table on the HCC 182 category page.
