ICD-10-CM S14.0XXS
CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

S14.0XXS is a billable ICD-10-CM diagnosis code for concussion and edema of cervical spinal cord, sequela. The 7th character S marks it as a sequela code, which reports a problem that remains after the original condition has resolved. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 52 through 53. The code is exempt from POA reporting. Coders also document this condition as concussion and edema of cervical spinal cord. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Injury, sequela.

S14.0XXS no longer risk-adjusts for Medicare Advantage: it mapped to HCC 72 under the retired CMS-HCC V24 model through payment year 2025 but maps to no category in the live V28 model. It still risk-adjusts in the PACE (CMS-HCC V22) category 72, ESRD (V21) category 72, and ESRD (V24) category 72 for payment year 2027.

Questions About S14.0XXSOverview

What is the ICD-10 code for concussion and edema of cervical spinal cord, sequela?

The ICD-10-CM code for concussion and edema of cervical spinal cord, sequela is S14.0XXS (sometimes written as S140XXS). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is S14.0XXS (Concussion and edema of cervical spinal cord) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report concussion and edema of cervical spinal cord, sequela on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What does the 7th character S in S14.0XXS mean?

The final character S makes this a sequela code: it reports a lingering problem that remains after the concussion and edema of cervical spinal cord itself has resolved, not the original event.

What MS-DRG does S14.0XXS group to?

When concussion and edema of cervical spinal cord, sequela is the principal diagnosis on an inpatient stay, it groups to MS-DRG 53, 52, with relative weights from 0.9723 to 1.7843 depending on complications. Higher weights mean higher Medicare reimbursement.

Is S14.0XXS 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 concussion and edema of cervical spinal cord, sequela on inpatient claims. The code appears in the Injuries to the neck (S10-S19) range of the CMS exempt list.

Does S14.0XXS risk-adjust for Medicare Advantage payment?

Not for Medicare Advantage. S14.0XXS mapped to HCC 72 in the retired CMS-HCC V24 model, which last determined payment in 2025, but it maps to no category in the live V28 model; see all codes that no longer risk-adjust. It still risk-adjusts in the PACE (CMS-HCC V22) category 72 (Spinal Cord Disorders/Injuries), ESRD (V21) category 72 (Spinal Cord Disorders/Injuries), and ESRD (V24) category 72 (Spinal Cord Disorders/Injuries).
