- Chronic Condition
Q06.8 is a billable ICD-10-CM diagnosis code for other specified congenital malformations of spinal cord. 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, 791, 793. The code is exempt from POA reporting. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Nervous system congenital anomalies.
For Medicare Advantage risk adjustment, Q06.8 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 Q06.8Overview
What is the ICD-10 code for other specified congenital malformations of spinal cord?
The ICD-10-CM code for other specified congenital malformations of spinal cord is Q06.8 (sometimes written as Q068). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is Q06.8 (Other congenital malformations of spinal cord) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other specified congenital malformations of spinal cord on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does Q06.8 group to?
When other specified congenital malformations of spinal cord is the principal diagnosis on an inpatient stay, it groups to MS-DRG 793, 791, 91, 92, 93, with relative weights from 0.7783 to 4.2192 depending on complications. Higher weights mean higher Medicare reimbursement.
Is Q06.8 exempt from POA reporting?
Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for other specified congenital malformations of spinal cord on inpatient claims. The code appears in the Congenital malformations of the nervous system (Q00-Q07) range of the CMS exempt list.
What is the ICD-9 equivalent of Q06.8?
Under the General Equivalence Mappings, other specified congenital malformations of spinal cord converts to ICD-9-CM 742.59 (spinal cord anomaly NEC). The mapping is approximate, so confirm the match fits the documentation.
What HCC is Q06.8?
Q06.8 (other specified congenital malformations of spinal cord) 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 Q06.8 risk-adjust for Medicare Advantage payment?
Yes. When documented and reported on a Medicare Advantage encounter, Q06.8 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.
