G82.21 is a billable ICD-10-CM diagnosis code for paraplegia, complete. 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. 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 138 closely related codes. Coders also document this condition as complete paraplegia. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Paralysis (other than cerebral palsy).
For Medicare Advantage risk adjustment, G82.21 maps to CMS-HCC Category 181 (Paraplegia) under the V28 model, adding a risk factor of about 0.942 for a community, non-dual, aged beneficiary in payment year 2027.

Patient EducationClinical
Paralysis
Paralysis is the loss of muscle function in part of your body. It happens when something goes wrong with the way messages pass between your brain and muscles. Paralysis can be complete or partial. It can occur on one or both sides of your body. It can also occur in just one area, or it can be widespread.

Questions About G82.21Overview
What is the ICD-10 code for paraplegia, complete?
The ICD-10-CM code for paraplegia, complete is G82.21 (sometimes written as G8221). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is G82.21 (Paraplegia) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report paraplegia, complete on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does G82.21 group to?
When paraplegia, complete 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 G82.21 a CC or MCC?
CMS lists G82.21 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 138 closely related codes in its exclusion list.
Can G82.21 be reported with a code from G80?
Not as a rule. The Excludes1 note at G82, which applies to G82.21, lists "congenital cerebral palsy (G80.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
What HCC is G82.21?
G82.21 (paraplegia, complete) maps to CMS-HCC Category 181 (Paraplegia), commonly written as HCC 181, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2027. It mapped to HCC 71 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 G82.21 risk-adjust for Medicare Advantage payment?
Yes. When documented and reported on a Medicare Advantage encounter, G82.21 adds a risk adjustment factor of about 0.942 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.563 to 0.942 depending on the payment segment). A more severe related category (HCC 180, HCC 191, and HCC 192) supersedes it when both are reported. See the full factor table on the HCC 181 category page.
