How to Write a Compliant Modified-Duty Offer Letter (With Refusal Documentation)

Why the Offer Letter Is the Document Carriers Ask for First

Picture this: your adjuster emails on a Thursday afternoon — audit request, response due Monday. The file they want is not the incident report, not the treatment notes, not the modified-duty job description. It is the offer letter. Specifically, they want to know whether you made a written offer, what it said, when the worker received it, and what happened next.

If that letter does not exist, or if it exists as a one-paragraph email that omits the pay rate or the start date, the carrier has no basis to reduce indemnity benefits for a refused offer. A benefit stream that could have slowed — or a reimbursement that could have started — stays open. The exposure sits on your claim record for the three-year experience window that shapes your EMR.

This is not a theoretical scenario. Because most RTW coordinators manage multiple concurrent cases, the paperwork slips. A verbal offer gets made; a follow-up email goes out without the required elements; nobody captures the worker's response in writing. Months later, a carrier auditor or defense attorney reconstructs what happened — and reconstructs it from whatever you can produce.

This article walks you through exactly what a compliant modified-duty offer letter must contain, how to structure it for the specific legal framework that applies (Texas, Washington, and all-state baseline), how to document acceptance and refusal, and how to file the record so it survives a carrier audit or a disputed-benefit proceeding.

What a Modified-Duty Offer Letter Must Accomplish

A modified duty offer letter serves four distinct functions simultaneously. Understanding all four prevents the common mistake of writing a letter that handles one function well while leaving the others unaddressed.

1. It defines the job clearly enough that a physician can approve it. The offer must describe the transitional position — tasks, physical demands, hours, schedule — with enough specificity that the attending provider can sign off on it without calling you for clarification. Vague language ("light duties as assigned") is not approvable because the physician cannot evaluate what the worker's body will actually be required to do. See our light-duty job description guide for how to structure that underlying description before you write the offer.

2. It establishes the offer as genuine and complete. In Texas, under 28 TAC §129.6, a Bona Fide Offer of Employment (BFOE) is a defined term. The rule lists specific elements the written offer must contain — position title, wages, hours, start date, physical requirements, the worker's right to have the offer reviewed by the treating physician. If any element is missing, the offer does not qualify as a BFOE, which means the carrier cannot use refusal to reduce or suspend indemnity benefits. Other states have analogous requirements even when the term "BFOE" is not used.

3. It creates an auditable timeline. The letter itself is a timestamped record: when the employer made the offer, what it said, and how it was delivered. That timeline matters for state-program reimbursement (Washington's Stay-at-Work program, for example, requires that the approved job description be submitted to the provider before the light-duty period begins) and for any later dispute about whether an offer was available when the worker claims otherwise.

4. It triggers — and documents — the worker's response. An offer letter that does not include a response mechanism or a follow-up process produces no evidence of acceptance or refusal. Both outcomes need to be in the file.

Required Elements: The Baseline Offer Letter

Regardless of state, a defensible modified-duty offer letter should include the following elements in plain, direct language. Build a template that carries all of them so nothing is omitted under time pressure.

Header and identification block

• Date of the letter (not "today" — write the actual date)
• Employer name, address, and claim number
• Worker's full legal name, home address, and job title at time of injury

Description of the transitional position

• Position title (distinct from the worker's pre-injury title if the duties differ substantially)
• Physical demands in measurable terms: maximum lift in pounds, maximum carry distance, whether the role requires standing, sitting, bending, reaching overhead, use of hands, operation of equipment
• Hours per day and days per week — including the specific schedule if it differs from the worker's regular schedule
• Duration: state that the role is temporary and tied to the medical restrictions, and include a reasonable end date or a review milestone

Compensation

• Hourly wage or salary for the transitional role — must equal or exceed the worker's regular wage for the position to be considered "like work" under most state frameworks
• Whether overtime, shift differentials, or bonuses that applied to the pre-injury role will or will not apply
• Benefits status (health insurance, leave accrual) during the transitional period

Reporting instructions

• Supervisor's name and contact
• Work location (including whether any remote component is available, if relevant)
• Start date — a specific calendar date, not "as soon as medically cleared"

Reference to medical restrictions

• A statement that the position was designed to fall within the restrictions documented in the most recent Attending Provider's Report (or equivalent form in the worker's state)
• A statement that the worker has the right to have the treating physician review the offer before accepting

Response deadline and method

• A specific date by which the worker must respond — in Texas, under 28 TAC §129.6, the carrier may reduce benefits on the earlier of the worker's rejection or the seventh day after the worker is deemed to have received the offer (deemed receipt is five days after mailing). Build your deadline to give the worker a genuine opportunity to respond while preserving that timeline.
• Clear instruction on how to respond: in writing (preferred), by phone with written follow-up, or in person with a witness

Signature blocks

• Employer representative signature, printed name, and title
• A worker signature and date line for acceptance — and a separate line for refusal, with a space for the worker to note the reason

The refusal signature line is not optional. If the worker refuses verbally and you have no signed document, your evidence of refusal is a self-serving internal note. A signed refusal is the record that survives a disputed-benefit proceeding.

State-Specific Requirements You Cannot Omit

Texas: Bona Fide Offer of Employment

In Texas, the term "Bona Fide Offer of Employment" has statutory weight. Under 28 TAC §129.6, a written BFOE must meet every requirement of the rule for the offer to have legal effect. A valid, refused BFOE allows the carrier to reduce or suspend indemnity benefits — but only if the offer was written and contained all required elements. (TDI-DWC RTW Guide, 2023)

If the worker refuses or simply does not respond, the carrier may treat the offered wages as post-injury earnings on the earlier of the worker's rejection or the seventh day after deemed receipt, with the offer deemed received five days after mailing. (28 TAC §129.6(g), 2024) That timeline means your delivery method and date of delivery must be documented precisely — certified mail with a return receipt, or in-person delivery with a witness signature.

Confirm the current list of required BFOE elements with TDI-DWC or your defense counsel before finalizing a Texas template; the specific rule language controls, not a summary.

Washington: Stay-at-Work Program Requirements

Washington's Stay-at-Work (SAW) program reimburses 50% of a worker's base wages for up to 120 days worked in a light-duty or transitional role, with a maximum of $25,000 per claim for injuries on or after January 1, 2025. (AGC of Washington, 2025) The reimbursement application is due within one year after the light-duty work is completed. (WA L&I, 2025)

Two details make the offer letter critical for SAW reimbursement:

First, the attending provider must approve the transitional job description in writing before the work begins. (WA L&I Complete Stay at Work Guide, 2024) If your offer letter goes out before that written approval is in hand, any days worked before approval are ineligible for reimbursement.

Second, a light-duty day worked outside the approved job description or the approved hours is ineligible — for example, if four hours per day were approved and the worker works six, that day does not count. (ERNwest, 2025) The offer letter's specificity about hours is therefore not a formality; it is the document that defines the reimbursable scope of work.

Submit the light-duty job description to the provider as early as possible, get written approval, then issue the offer letter referencing that approval. (WA L&I Complete Stay at Work Guide, 2024) Partial days count as one reimbursable day. (WA L&I Complete Stay at Work Guide, 2024)

Verify current form versions and any program updates directly with WA L&I before filing.

All Other States

If your operation is outside Texas and Washington, the absence of a named state framework does not mean the offer letter is discretionary. Every state workers' comp system evaluates whether an employer made a genuine, documented offer of available modified work. The absence of a written offer — or a letter that omits compensation, hours, or physical demands — undermines any argument that suitable work was available and offered. Work with your carrier or defense counsel to identify your state's specific requirements before a disputed claim surfaces.

Delivering the Offer and Establishing Receipt

An offer letter that cannot be proven to have reached the worker is worth little in a disputed proceeding. Use at least one delivery method that creates a receipt record:

• Certified mail, return receipt requested — USPS green card creates a date-stamped proof of delivery. Keep the original green card in the claim file; scan and attach it to the electronic record.
• In-person delivery with witness — If you present the letter in person, have a second person present. Both of you sign and date a delivery memo the same day. Give the worker a copy.
• Email with read receipt — Acceptable as a supplement, not as the primary method for high-stakes offers. Email receipts are easily disabled and do not establish that the worker read or understood the letter.

Document the delivery in your case notes the same day it happens: who delivered, by what method, to what address or in what location, at what time.

---

Documenting Acceptance

If the worker accepts the offer, file the signed acceptance page with the claim record immediately. Note the return-to-work date in your case management log. For Washington SAW claims, the clock on reimbursable days starts on the first day the worker performs the approved transitional duties — not the date the offer was signed.

Confirming acceptance does not close your documentation obligation. Track each day worked against the approved job description and the approved hours. Any material change to the duties or schedule — even a supervisor informally expanding the scope — should trigger an amended offer letter with fresh physician approval.

Documenting Refusal of Light Duty

Refusal documentation is the piece most often missing from a claim file — and it is the piece carriers ask for first when questioning whether benefits should have been reduced. Our light-duty refusal documentation guide covers the full process; the key steps in the context of the offer letter are:

1. Capture the refusal in writing at the moment it occurs. If the worker signs the refusal line on the offer letter, that is your primary document. If the worker refuses verbally, follow up the same day with a written memo addressed to the worker: "On [date], at [time], you declined the modified-duty offer letter dated [date]. Your stated reason was [reason, verbatim if possible]. Please contact [name] by [date] if this was a misunderstanding." Send it certified mail.

2. Note whether the worker gave a reason. Some refusals are medical — the worker or the treating physician contends the role exceeds restrictions. Others are non-medical ("I don't want to do that job," "I'm not ready to come back"). The reason affects how the carrier and potentially a hearing officer will evaluate the refusal.

3. If the refusal is medically based, obtain clarification from the treating provider. Ask the physician — in writing, through the appropriate channel for your state — whether the offer as written exceeds the worker's current restrictions. If it does, amend the offer. If it does not, the physician's written response becomes part of the file.

4. Notify the carrier promptly. In Texas, the five-working-day window after which the carrier may act on a refused BFOE (28 TAC §129.6, 2024) presupposes that the carrier knows the offer was refused. Send the carrier a copy of the refused offer and your delivery documentation the same day.

5. Keep the record together. The offer letter, delivery proof, refusal documentation, and carrier notification should be stored as a single bundle in the claim file — not scattered across email folders, a shared drive, and a paper binder. When an auditor asks for the offer-and-refusal record, you want to produce it as one coherent file.

Why the Offer-and-Refusal Record Shapes Your EMR

The connection between a single offer letter and your experience modification rate runs through claim duration. Indemnity benefits — weekly wage-replacement payments — are the largest driver of lost-time claim cost. The average U.S. workers' comp claim across all causes runs $47,316 (NSC/NCCI Injury Facts, 2025); lost-time claims with extended durations far exceed that figure.

A valid modified-duty offer, accepted and worked, converts a potentially long lost-time claim into a shorter one or eliminates the indemnity period entirely. A valid offer, refused, gives the carrier the legal basis to reduce or suspend benefits — which also controls claim cost. An invalid offer, or no offer at all, leaves the benefit stream running at full rate regardless of what work was available.

EMR uses a three-year experience window, excluding the current year. (Higginbotham, 2026) A claim that runs longer than it needed to because the offer documentation was defective stays elevated in your EMR for roughly three years. The offer letter is not administrative overhead; it is a direct input to your insurance cost.

Building a Template You Will Actually Use Under Pressure

The offer letter that gets written correctly is the one that exists as a complete, fill-in template before you need it — not the one you draft from scratch at 4:30 on a Friday when a claim just opened and the adjuster is asking for a status update.

A good template:

• Carries every required field as a labeled blank — no field can be accidentally skipped
• Includes the refusal signature line by default, so it is never omitted
• Has a version for each state framework your operation covers (at minimum, a Texas BFOE version, a Washington SAW version, and an all-states baseline)
• Is stored where the person who needs it — the RTW coordinator, the HR manager, the site supervisor — can find it in two minutes

For a set of ready-to-use templates built to these specifications, see our Modified Duty Offer Letter Templates in the resource store. Each template is structured to carry the elements described in this article; adapt the language to your specific role inventory and have your counsel review it for your state before first use.
