Your Treatment Was Denied: A Worker’s Checklist for the Doctor, Records, and IMR Form

A worker-focused response plan after utilization review denies or modifies recommended care, including what to save, ask the doctor, submit, and track.

A treatment denial can arrive as a dense utilization-review letter while the worker is still in pain or off work. Start with the document in front of you. Preserve it, identify what the doctor requested, and ask the treating office what clinical information supported the request. The response should be accurate and timely, not rushed or speculative.

The DWC explains medical care, utilization review, and medical provider networks on its official medical-care page. Its Independent Medical Review page provides current administrative information.

Save every page of the UR notice and its delivery information

Do not keep only the first page. Save the decision, reviewer information, rationale, cited guideline, treatment description, instructions, IMR form, envelope, email, fax information, and any attachments. Write down the date and method of receipt without altering the original.

Check whether the letter approved part of the request, changed the frequency or duration, or denied it entirely. A modified request may still leave an unresolved need. Highlight the exact treatment, diagnosis or body part, and stated reason so the doctor can address the same issue.

Ask the requesting physician what was submitted

Contact the office that requested authorization. Ask for a copy of the request for authorization, the report supporting it, and any records sent with it. Confirm whether the office received the UR decision and whether it plans a peer-to-peer discussion, corrected submission, new request, or supporting statement. Do not assume a repeated request is appropriate without asking why the first one was modified or denied.

A useful medical explanation connects the requested service to current findings, diagnosis, prior care and response, functional goals, and the applicable treatment guideline. The worker should describe symptoms and function honestly; the physician supplies the medical reasoning.

Collect records that bear on the disputed treatment

More paper is not always better. Gather the records that explain the present condition and requested service: recent examination findings, imaging, operative reports, therapy progress, medication history, prior treatment response, and the treating physician’s recommendation. Keep the records in date order and note which ones were supplied to the treating office or claims administrator.

Read the IMR instructions and act on the printed deadline

Cal. Lab. Code § 4610.5 allows a worker to request IMR after a covered UR denial or modification based on medical necessity. The statute sets a 10-day request period for formulary disputes and a 30-day period for other medical-treatment disputes, measured from service of the UR decision. The DWC hosts the current IMR forms.

Complete the form legibly, follow the delivery instructions, keep an exact copy, and preserve proof of submission. If the form or required notice is missing, the statute contains a timing rule, but do not wait to investigate the problem. Ask the DWC Information and Assistance Unit or counsel how the actual notice and service facts affect the response.

Keep attending authorized care and update the work record

A disputed service does not erase every other authorization. Confirm which appointments, medications, therapy, or evaluations remain approved. Continue authorized care unless the treating provider changes the plan. Save new work-status notes and deliver them to the employer through a traceable channel.

If pain or function changes, report the change to the treating provider. Do not independently change medication or exceed restrictions. If transportation, interpretation, or network access is interfering with care, document the problem and request assistance.

Track whether the treatment is later authorized or withdrawn

Section 4610.5 allows the IMR process to end if the employer authorizes the disputed treatment or the requesting physician withdraws the request. Save any later authorization and confirm scheduling details with the provider. If the requested service changes, ask whether the new request replaces or supplements the old one.

When a report itself is incomplete, the next question may differ from an IMR dispute. Mishra X’s article on medical care while a claim is under investigation explains the separate early-claim treatment rule. Our Workers’ Compensation page places treatment disputes within the larger claim.

Frequently Asked Questions

Should I ask my doctor to submit a new request?

Ask the physician why the first request was modified or denied and what response is medically appropriate. A corrected or new request may be useful in some circumstances, but it should address the actual decision rather than simply duplicate the same submission.

What records may I provide for IMR?

Section 4610.5 permits relevant information supporting medical necessity, including the treating recommendation and material explaining the condition or urgent need. Focus on records that bear on the disputed treatment and keep a copy of what was submitted.

What if the UR packet did not include the IMR form or instructions?

Preserve the incomplete packet and delivery evidence. The statute addresses missing required notice, but the practical response is to obtain the current form and prompt guidance rather than assume no deadline can apply.

The Bottom Line

What this means for you: After a treatment denial, preserve the whole notice, involve the requesting doctor, collect targeted records, submit the correct form with proof, and continue tracking authorized care and work restrictions. Each step should respond to the actual treatment request and the actual UR rationale.
