Denied epidural steroid injection: what independent reviewers actually decided

Almost every epidural injection that survived neutral review had one thing in common, and it was not the imaging.

Injection of a corticosteroid into the epidural space by interlaminar, caudal or transforaminal approach, billed by level and approach with imaging guidance where used.

Read this as a base rate, not as your odds

These are decisions about other patients, in one state, that had already been through the plan's own internal appeal and were then sent to an outside reviewer. That population is self-selected toward disputes worth pursuing, so the rate says what happened to cases like this at that stage — not what will happen to a specific claim. It is not medical or legal advice.

Why plans deny epidural steroid injection

  • The policy requires a documented period of conservative care first and the record does not evidence it.
  • A repeat injection is denied because the response to the previous one is not documented in measurable terms.
  • The number of injections in a period exceeds a policy limit.
  • Imaging is read as not showing a finding that correlates with the described radicular pattern.

What actually carried the cases that won

Prior treatment appeared in 96% of the overturned decisions — one of the sharpest single signals in the corpus. The practical reading is blunt: the imaging argument is not what carries these appeals. What carries them is a documented conservative course and, on a repeat request, a measured response to the prior injection. Peer-reviewed literature and clinical guidelines were the authorities.

Shares are of the overturned decisions and do not sum to 100% — a single decision often rested on more than one, and some rested on none of these.

epidural steroid injection denials — frequently asked

Is a denied epidural steroid injection worth appealing?
55% of 101 California independent medical reviews were overturned — a narrow majority, decided far more by documentation than by the clinical question.
What is the most common gap?
The conservative course. Nearly every reversal documented it; the denials that stood generally did not. Therapy, medication, activity modification — with dates and outcomes.
How should a repeat injection be justified?
With the previous one's result as a measurement: how much relief, for how long, against a baseline. Policies that limit repeats do it by reference to a response threshold that a narrative cannot satisfy.
