Two letters can appear to contradict each other while deciding different things: An accepted injury and denied treatment, a return-to-work release and an unavailable job, or stopped temporary payments and a later permanent-disability estimate. This FAQ helps you compare those decisions without treating one as the answer to every benefit question. Start with the question matching the document you received; keep the exact wording and dates beside it.

Can I receive medical care while liability is investigated?

Yes. Within one working day after you file the completed DWC-1 claim form, the employer or claims administrator must authorize treatment consistent with the applicable treatment guidelines, up to $10,000 while the claim is awaiting acceptance or rejection. This pays for qualifying care; it is not a $10,000 cash benefit or final acceptance of the injury claim. The DWC claim-form instructions, Notice of Potential Eligibility, page 1, explain that duty.

Compare the completed DWC-1 delivery record, the administrator’s claim-status letter and the particular treatment authorization. The delivery record identifies the filing trigger; the status letter shows whether investigation continues; the authorization identifies the care actually approved. If care is refused during investigation, preserve the written reason and promptly ask the claims administrator or employer to authorize the requested care. Our investigation-period medical-care guide explains how to distinguish a claim-status problem from a treatment, access or authorization dispute.

How are temporary and permanent disability different?

Temporary disability replaces part of wages during qualifying recovery; permanent disability compensates lasting impairment and diminished earning capacity under the rating system. A letter ending temporary payments and an estimate of permanent disability therefore need separate review. Compare the date and medical reason for ending temporary disability with the physician’s lasting-impairment findings and the payment explanation. A permanent-disability estimate is not the same as the final award.

What if work restrictions cannot be accommodated?

Preserve every restriction and written offer. Compare actual duties, schedule, location, wages, and duration with the physician’s limits. For example, a ten-pound lifting limit and a letter saying light duty is available do not establish whether the offered task actually fits. Ask for the duties in writing and give the treating physician an accurate description. Modified-work and voucher consequences require the precise offer and dates.

Who decides disputed medical issues?

Treating physicians, utilization review, independent medical review, and QME or AME evaluators have different roles. A qualified medical evaluator (QME), or an agreed medical evaluator (AME) in a represented case, may address medical-legal disputes. Identify the exact question—work causation, disability or apportionment—before assuming that the evaluator can resolve a treatment-necessity denial. Put the notice beside the medical report it addresses; disagreement between two doctors is not a description of the procedure by itself.

Can a claim cover cumulative trauma?

Potentially. A report may describe months of repetitive exposure while a claim letter lists one legal injury date. Those entries are not necessarily inconsistent: Exposure period and legal date serve different purposes. Preserve the job history, disability evidence and information about when the work connection became known so the dates can be evaluated instead of casually changed to match.

What should be ready for a WCAB conference?

Organize the application, answers, medical reports, benefit printout, wage proof, notices, exhibits, witness list, issues, and proposed stipulations. The pretrial statement can limit later issues and evidence.

What should be done immediately after a work injury, and who may qualify?

Report the event or condition, obtain appropriate medical attention, request a DWC-1, and preserve job, witness, wage, and medical records. Coverage generally turns on an employee relationship and injury arising out of and occurring in the course of work, but status and causation can be disputed. The DWC injured-worker FAQ is a starting point, not an individualized eligibility ruling.

Which dates control notice and claim-filing deadlines?

Build a chronology for injury or exposure, first symptoms, disability, knowledge that work may be involved, employer notice, and each filing or denial. Different rules can govern a specific injury, cumulative trauma, death claim, benefit petition, or review request. Act promptly and verify the controlling notice and statute rather than relying on one generic deadline.

How does an MPN affect doctor choice and transfer requests?

Ask whether an approved MPN applies, obtain its notice and directory, and document each selection, transfer request, second or third opinion, and continuity-of-care issue. Predesignation and statutory exceptions may change the analysis. Consult the official DWC MPN questions and answers.

How do wage history and rate caps affect disability benefits?

Temporary and permanent disability use different formulas and statutory limits. For temporary disability, assemble wage statements plus overtime, commissions, tips, bonuses, lodging, and concurrent-job earnings; irregular income should not be reduced to an unsupported estimate. The DWC benefit guidance identifies the framework and current-rate resources.

What should be preserved after a treatment denial?

Keep the request for authorization, supporting report, utilization-review determination, envelopes or electronic service record, IMR application, medical records, and deadline calendar. A claim-acceptance letter does not itself authorize every later treatment request. Conversely, a medical-necessity denial does not necessarily withdraw acceptance of the injury. Read which treatment and reason the UR determination identifies. IMR addresses medical necessity; QME or AME procedures address other medical-legal disputes. Follow the DWC IMR instructions attached to the actual determination.

What happens when the carrier denies the whole claim?

Request the written denial and stated grounds, compare them with the DWC-1, employer report, medical history, witness evidence, and wage record, and determine whether an adjudication filing or hearing request is needed. A whole-claim denial is different from a UR letter rejecting one requested treatment. If both exist, identify the liability issue and medical-necessity issue separately before selecting a response. A denial does not resolve disputed facts by itself, but missing a governing deadline can limit review.

How should an injured worker evaluate counsel and fees?

Ask who will perform the work, how medical and hearing issues are handled, how often status will be reported, what records are needed, how statutory fee approval operates, and which costs or liens may affect recovery. Ask counsel to identify which apparent conflict needs action first and what remains unknown. A promise of a settlement figure does not explain a treatment letter, a work restriction or a disputed rate. Avoid any lawyer who guarantees a result before reviewing the complete record.
