Work Comp Clarity
Medical treatment delays are one of the most common problems injured workers face in California workers’ compensation claims. Learn why treatment gets delayed or denied — and what you can do to protect your care.
Why Does Workers’ Comp Medical Treatment Get Delayed or Denied?
In California workers’ compensation, most medical treatment must be approved through a formal review process before it can happen.
This process is called Utilization Review (UR).
Treatment may be delayed or denied for several common reasons:
-
The insurance company is reviewing whether the treatment is medically necessary
-
Your doctor’s report does not include enough medical detail
-
The requested treatment does not match California’s Medical Treatment Guidelines (MTUS)
-
The insurance company disputes whether your injury is work-related
-
Additional medical opinions are requested
Even legitimate treatment can be delayed simply because the paperwork or medical documentation is incomplete.
Why This Matters for Your Work Comp Case
California workers’ compensation operates under strict medical approval rules.
If treatment is delayed, it can slow your recovery and impact your benefits.
If treatment is denied, the insurance company may argue:
-
The treatment is not medically necessary
-
The treatment is unrelated to your work injury
-
The treatment is premature or unsupported
-
The medical documentation is insufficient
Delays in treatment can affect:
-
Your ability to heal properly
-
Temporary disability payments
-
Future permanent disability ratings
-
Your overall claim timeline
Understanding the reason for the delay helps you take the correct next step.
Steps You Can Take to Protect Your Medical Treatment
Confirm your doctor submitted a complete treatment request
Incomplete medical reports are one of the biggest causes of delays.
Your doctor must clearly explain:
-
Your diagnosis
-
Why the treatment is needed
-
How it relates to your work injury
▶ Follow up if you have not received a decision
Workers’ compensation Utilization Review decisions must follow strict timelines. If you hear nothing, follow up with your doctor or claims adjuster.
▶ Request the denial reason in writing
You have the right to receive a written explanation if treatment is denied. This document explains your options.
▶ Keep copies of all medical paperwork
Always keep:
-
Treatment requests
-
Medical reports
-
UR notices
-
Denial letters
Documentation is critical if you need to challenge the decision later.
▶ Know that denied treatment can often be reviewed
In California, denied treatment may be reviewed through:
-
Independent Medical Review (IMR)
-
Additional medical evaluation
-
Supplemental medical reporting
-
Many denials are overturned once the correct documentation is submitted.
How Long Can Workers’ Comp Take to Approve Medical Treatment in California?
Most treatment requests must be reviewed within legally required timelines once submitted.
However, delays often occur when:
-
The treatment request is incomplete
-
Additional medical records are requested
-
The claim itself is under investigation
If your treatment is urgent, your doctor can sometimes request expedited review.
Is It Normal for Workers’ Comp to Deny Treatment?
Yes. Treatment denials are common in workers’ compensation claims.
A denial does NOT necessarily mean the treatment will never be approved.
Often the issue is documentation, medical justification, or guideline compliance — not the treatment itself.
