In Texas workers’ compensation, an impairment rating is a percentage that a certified doctor assigns to the permanent damage left by your workplace injury once your condition has stabilized, and that percentage decides how many weeks of impairment income benefits you receive and whether you qualify for longer-term supplemental benefits down the road. Each percentage point equals three weeks of checks paid at 70% of your average weekly wage, so a 10% rating produces 30 weeks of payments and a 15% rating opens the door to an additional benefit category entirely.1Texas Department of Insurance. Impairment Income Benefits (IIBs)
When the Rating Gets Assigned
The rating clock starts at maximum medical improvement (MMI). That’s the point where your treating doctor decides further treatment isn’t likely to make you meaningfully better. Once you hit MMI, the doctor evaluates whatever lasting damage remains and translates it into a whole-body impairment percentage.2State of Texas. Texas Labor Code 408.123 – Certification of Maximum Medical Improvement; Assignment of Impairment Rating
The percentage is expressed as whole-body impairment, not as a rating on the specific body part injured. A blown-out knee doesn’t get a knee rating that stays isolated. The doctor converts the functional loss in that joint to a percentage of your overall body. A 0% rating means the doctor found no permanent damage worth rating. Anything above zero triggers impairment income benefits.
Only doctors who hold current certification from the Division of Workers’ Compensation (DWC) can assign the rating. If your treating doctor isn’t certified, they refer you to one who is. The evaluation typically includes range-of-motion measurements, strength testing, neurological exams, and a review of imaging like MRIs or CT scans that document structural damage. Texas requires doctors to use the American Medical Association’s Guides to the Evaluation of Permanent Impairment when calculating the number; the statute defaults to the third edition but authorizes the commissioner to adopt a later version, and the fourth edition has been in use for years.3State of Texas. Texas Labor Code Chapter 408 – Workers’ Compensation Benefits – Section 408.124
The evaluating doctor records everything on DWC Form-069, which lists the MMI date, the impairment percentage, and the medical reasoning behind it.4Texas Department of Insurance. Report of Medical Evaluation (DWC Form-069) The MMI date on the form can’t be set in the future, and the form has to carry the signature of a DWC-authorized doctor.5Cornell Law Institute. 28 Texas Administrative Code 130.12 – Finality of the First Certification of Maximum Medical Improvement and/or First Assignment of Impairment Rating Without a valid Form-069, there’s no official rating.
How the Percentage Turns Into Money
The math is simple. Multiply your rating by three to get the number of weeks of impairment income benefits (IIBs). Each weekly payment equals 70% of your average weekly wage (AWW).6State of Texas. Texas Labor Code Chapter 408 – Workers’ Compensation Benefits – Section 408.126 A 10% rating yields 30 weeks. A 15% rating yields 45 weeks. A 20% rating yields 60 weeks.
The weekly amount is capped. For injuries occurring during fiscal year 2026 (October 1, 2025, through September 30, 2026), the maximum weekly IIB payment is $890 and the minimum is $191.7Texas Department of Insurance. State Average Weekly Wage (SAWW) / Maximum and Minimum Weekly Benefits The maximum is 70% of the state average weekly wage, which is $1,271.05 for FY 2026. DWC recalculates these caps every October 1, so the numbers that apply to your claim depend on when your injury occurred, not when the rating gets assigned.
Your AWW is normally calculated by adding your wages from the 13 consecutive weeks before the injury and dividing by 13. Shorter tenure and multiple jobs are handled by separate rules in the statute.8State of Texas. Texas Labor Code Chapter 408 – Workers’ Compensation Benefits – Section 408.041
A Quick Example
Say your AWW is $1,000. Seventy percent is $700 per week, below the $890 cap, so your weekly IIB check is $700. With a 12% rating, you receive 36 weeks of payments, or $25,200 total. If your AWW were $1,500, 70% would come to $1,050, and the $890 cap would trim your weekly check to that number.
Why 15% Is the Threshold That Matters Most
A rating of 15% or higher unlocks supplemental income benefits (SIBs), which can continue long after your IIBs run out.9State of Texas. Texas Labor Code Chapter 408 – Workers’ Compensation Benefits – Section 408.142 Many injured workers don’t realize this second benefit tier exists until their IIB payments end and they discover they were one percentage point short.
To qualify for SIBs, all four of these have to be true:
- An impairment rating of 15% or higher from the compensable injury.
- You earn less than 80% of your pre-injury AWW, or aren’t working at all, as a direct result of your impairment.
- You haven’t chosen to receive a lump-sum advance (a commutation) of your remaining IIBs.
- You comply with the job-search requirements adopted by DWC.
SIBs also pay 70% of your AWW and carry the same $890 weekly maximum for FY 2026 injuries. Even if you returned to work after IIBs ended, you can claim SIBs within one year of the IIB period’s end date if your earnings later drop below 80% of your pre-injury wage because of the impairment. That’s why the gap between a 14% rating and a 15% rating is worth far more than a single percentage point suggests.
Disputing a Rating You Think Is Too Low
Disagreements over impairment ratings are common, and the dispute process has several layers.
The Designated Doctor
If you, your representative, or the insurance carrier disagrees with the treating doctor’s rating, any party can ask DWC to appoint a designated doctor for an independent evaluation.10Texas Department of Insurance. Designated Doctor Program DWC picks that doctor from a trained and certified pool. Neither you nor the carrier chooses.
The designated doctor’s report carries what the law calls presumptive weight. DWC will adopt that doctor’s rating unless the preponderance of the other medical evidence points the other way.11Justia Law. Texas Labor Code Chapter 408 – Workers’ Compensation Benefits – Section 408.125 Overcoming that presumption is difficult. You need multiple medical opinions, strong objective findings, and a clear account of where the designated doctor went wrong. In practice, most final ratings track the designated doctor’s number.
The 90-Day Finality Window
The first valid certification of MMI and impairment rating can become final if nobody disputes it within 90 days.5Cornell Law Institute. 28 Texas Administrative Code 130.12 – Finality of the First Certification of Maximum Medical Improvement and/or First Assignment of Impairment Rating Once finality attaches, reopening the rating gets much harder. If you receive a rating you believe is too low, request a designated doctor exam or file a dispute before the 90 days run out.
Benefit Review Conferences and Hearings
If the designated doctor step doesn’t resolve the dispute, the next stop is a Benefit Review Conference, an informal mediation with a DWC mediator that the parties are required to attempt before escalating. When the BRC fails, the case moves to a Contested Case Hearing before a DWC administrative law judge, who reviews the evidence and issues a binding decision. Either side can appeal to the DWC Appeals Panel and, from there, to state district court.
Documentation That Decides Disputes
Form-069 is the backbone of the process, but it’s not the only document that matters. Building support for your rating, or against a low one, starts well before MMI.
Keep organized copies of all diagnostic imaging, operative reports if you had surgery, physical therapy records showing progress or plateaus, and specialist reports. If you contest a rating at a BRC or CCH, independent medical evaluations and affidavits from your treating physicians explaining why their assessment differs from the designated doctor’s help your case. Functional capacity evaluations, which formally measure the physical tasks you can actually perform, carry particular weight because they produce objective data rather than self-reported complaints. Adjusters and administrative law judges decide based on what’s in the file, not on what you remember telling your doctor.
Tax and Social Security Effects
Workers’ compensation benefits, including IIBs and SIBs, are fully exempt from federal income tax. The IRS excludes amounts received under a workers’ compensation act from gross income, and the exemption extends to survivors if benefits continue after your death.12Internal Revenue Service. Publication 525 (2025), Taxable and Nontaxable Income One exception: if you later receive a retirement pension from an employment-based plan, the portion based on your age or years of service is taxable even if you retired because of the workplace injury.
The interaction with Social Security Disability Insurance is less friendly. If you receive both workers’ compensation and SSDI, Social Security may reduce your disability check so the combined total doesn’t exceed 80% of your average earnings before the disability began.13Social Security Administration. Reduction to Offset Workers’ Compensation or Public Disability Benefits The offset applies month by month until you reach age 62. Your workers’ comp payment doesn’t change, but your SSDI check shrinks if the combined amount goes over the line. That surprise catches a lot of people, so budget with the offset in mind if you plan to draw both.
