G83.4 — Cauda equina syndrome
G83.4 is a billable, specific ICD-10-CM code for cauda equina syndrome. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Neurogenic bladder due to cauda equina syndrome
Other codes that can never be billed with G83.4
These codes carry an Excludes1 note pointing at G83.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading G83.4 alone.
Risk adjustment
G83.4 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:
- HCC 182 Spinal Cord Disorders/Injuries0.478 RAF
Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.
Medicare coverage
G83.4 is named in 21 Medicare coverage policies — 21 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
