Polio and Post-Polio Syndrome
Polio, or poliomyelitis, is a disease that spreads from person to person. It is caused by the poliovirus. The virus attacks the nervous system. In serious cases, it can cause paralysis (where you can't move parts of the body). The paralysis may be lifelong and can sometimes be life-threatening.

Questions About G14Overview
What is the ICD-10 code for postpolio syndrome?
The ICD-10-CM code for postpolio syndrome is G14. It is billable on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
Is G14 (Postpolio syndrome) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report postpolio syndrome on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does G14 group to?
When postpolio syndrome is the principal diagnosis on an inpatient stay, it groups to MS-DRG 91, 92, 93, with relative weights from 0.7963 to 1.7562 depending on complications. Higher weights mean higher Medicare reimbursement.
What is the ICD-9 equivalent of G14?
Under the General Equivalence Mappings, postpolio syndrome converts to ICD-9-CM 138 (late effect acute polio). The mapping is approximate, so confirm the match fits the documentation.
What HCC is G14?
G14 (postpolio syndrome) 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 2026. It does not map to any RxHCC in the Part D prescription drug model.
Does G14 risk-adjust for Medicare Advantage payment?
Yes. When documented and reported on a Medicare Advantage encounter, G14 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.
