CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

S14.159D is a billable ICD-10-CM diagnosis code for other incomplete lesion at unspecified level of cervical spinal cord, subsequent encounter. The 7th character D marks it as a subsequent encounter code, used during routine care in the healing or recovery phase. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 949 through 950. The code is exempt from POA reporting. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Spinal cord injury (SCI), subsequent encounter.

For Medicare Advantage risk adjustment, S14.159D 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.

Questions About S14.159DOverview

Is S14.159D a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other incomplete lesion at unspecified level of cervical spinal cord, subsequent encounter on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What does the 7th character D in S14.159D mean?

The final character D marks a subsequent encounter: use it for routine care while the other incomplete lesion at unspecified level of cervical spinal cord is healing, after active treatment has ended.

What MS-DRG does S14.159D group to?

When other incomplete lesion at unspecified level of cervical spinal cord, subsequent encounter is the principal diagnosis on an inpatient stay, it groups to MS-DRG 950, 949, with relative weights from 0.7661 to 1.1231 depending on complications. Higher weights mean higher Medicare reimbursement.

Is S14.159D 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 incomplete lesion at unspecified level of cervical spinal cord, subsequent encounter on inpatient claims. The code appears in the Injuries to the neck (S10-S19) range of the CMS exempt list.

What is the ICD-9 equivalent of S14.159D?

Under the General Equivalence Mappings, other incomplete lesion at unspecified level of cervical spinal cord, subsequent encounter converts to ICD-9-CM V58.89 (other specfied aftercare). The mapping is approximate, so confirm the match fits the documentation.

What HCC is S14.159D?

S14.159D (other incomplete lesion at unspecified level of cervical spinal cord, subsequent encounter) 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. It does not map to any RxHCC in the Part D prescription drug model.

Does S14.159D risk-adjust for Medicare Advantage payment?

Yes. When documented and reported on a Medicare Advantage encounter, S14.159D 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.
