When a workplace injury prevents you from working, the workers’ compensation system replaces a portion of your lost wages through disability benefits. During the period between the injury and the point where your condition stabilizes — either through full recovery or a determination that your disability is permanent — your benefits fall into one of two temporary categories: Temporary Total Disability or Temporary Partial Disability. Which classification applies to you depends on your ability to work, and the classification directly determines how much you receive each week.
Understanding the distinction between TTD and TPD matters because the classifications are not always straightforward. A worker who cannot do their regular job but could theoretically do some other type of work may be classified differently depending on the specific facts. And the classification can change over the course of recovery as your condition improves or worsens.
Temporary Total Disability
Temporary Total Disability, or TTD, applies when you are completely unable to work in any capacity due to your injury. Not unable to do your regular job — unable to work at all. A construction worker recovering from spinal fusion surgery who cannot sit, stand, or lift for more than a few minutes is temporarily totally disabled. A warehouse worker with a severely fractured leg who cannot walk or bear weight is temporarily totally disabled. The key is that the disability is total: you cannot perform any gainful employment, even in a reduced or modified capacity.
The TTD benefit is two-thirds of your average weekly wage, up to the statutory maximum. For injuries on or after July 1, 2023, the maximum is $1,145.43 per week. The benefit is tax-free. TTD benefits continue for as long as you remain temporarily totally disabled — until you recover enough to return to work in some capacity, or until your condition stabilizes and is reclassified as a permanent disability.
Your treating physician determines your disability classification based on clinical findings. The doctor assesses your functional limitations — your ability to sit, stand, walk, lift, carry, drive, use your hands, and perform other physical activities — and determines whether those limitations prevent you from working entirely. This assessment is documented in the medical record and reported to the Board through the C-4 form.
Temporary Partial Disability
Temporary Partial Disability, or TPD, applies when your injury limits your ability to work but does not prevent you from working entirely. You can do some work, but not at your full pre-injury capacity. A worker with a back injury who can perform light-duty tasks but cannot lift heavy objects may be classified as temporarily partially disabled. A worker who can work four hours a day but not a full shift may qualify. A worker who returns to a lower-paying position because the injury prevents them from doing their prior job falls into this category as well.
The TPD benefit is calculated as two-thirds of the difference between your pre-injury average weekly wage and your current earning capacity. If your AWW before the injury was $900 and you are now able to earn $400 per week in a light-duty role, the difference is $500. Your TPD benefit is two-thirds of $500, or $333.33 per week. If your employer offers you a modified position that pays the same as your pre-injury wages, your TPD benefit may be zero — even if the work is different from what you were doing before.
The concept of “earning capacity” is important and sometimes contentious. Earning capacity is not necessarily what you are actually earning. It is what you are capable of earning given your medical restrictions. If your doctor clears you for light-duty work and light-duty work is available at $400 per week, your earning capacity may be set at $400 even if you have not actually returned to work. This distinction can affect your benefit amount.
How your disability classification can change
Disability classifications are not permanent during the temporary phase. As your condition improves, your classification may shift from TTD to TPD. If you were initially unable to work at all and then recover enough to perform light-duty tasks, the carrier may reclassify you as TPD and reduce your weekly benefit accordingly.
This reclassification often follows an Independent Medical Examination. The carrier’s IME physician may conclude that your condition has improved to the point where you can perform some type of work, even if your treating physician disagrees. If the two opinions conflict, the dispute goes to a Workers’ Compensation Law Judge for resolution.
Conversely, if your condition worsens — if a light-duty worker suffers a setback and becomes unable to work again — the classification can shift back from TPD to TTD. Changes in classification should be supported by medical evidence from your treating physician. Document any worsening of symptoms with your doctor immediately so the medical record reflects the change.
Light duty, modified duty, and return to work
At some point during your recovery, your employer may offer you a light-duty or modified-duty position. This is a job with reduced physical demands that accommodates your medical restrictions. The offer may come from the employer directly or may be prompted by the insurance carrier after an IME concludes that you can perform some type of work.
Whether to accept a light-duty offer is a decision that should be made carefully. If the offer is consistent with your medical restrictions and pays the same as your pre-injury job, refusing it without a medical reason may result in a reduction or suspension of benefits. The Board may determine that your earning capacity equals the wages offered by the light-duty position, even if you declined it.
If the light-duty offer is not consistent with your medical restrictions — if it requires physical activities your doctor has said you should not perform — you are not obligated to accept it. Your treating physician’s assessment of your functional limitations controls. If there is a dispute about whether the offered position fits within your restrictions, the matter can be raised at a hearing.
If you accept a light-duty position and find that the work aggravates your injury, report the problem to your doctor and to your employer immediately. Do not push through pain in a way that makes the injury worse. Your health comes first. A worsened condition is documented through the medical record and may result in a reclassification back to TTD.
Common disputes about temporary disability classification
The most common dispute involves the carrier arguing that a worker classified as TTD should be reclassified as TPD. The carrier’s position is typically supported by an IME report concluding that the worker can perform some type of work. The injured worker’s treating physician may disagree, maintaining that the worker remains unable to work in any capacity. The Workers’ Compensation Law Judge resolves this dispute by weighing the medical evidence from both sides.
Another common dispute involves the calculation of earning capacity for TPD purposes. The carrier may argue that the worker’s earning capacity is higher than the worker contends, which reduces the TPD benefit. Factors the Board considers include the worker’s medical restrictions, age, education, prior work experience, and the availability of suitable employment in the local labor market.
These disputes have real financial consequences. The difference between TTD and TPD can be hundreds of dollars per week. The difference between a high earning capacity and a low earning capacity for TPD purposes can be equally significant. Do not assume the carrier’s classification is correct. If you believe your disability is more severe than the carrier’s assessment reflects, raise the issue with your attorney.
How Schwartzapfel Holbrook handles temporary disability classification issues
At Schwartzapfel Holbrook, we monitor disability classifications throughout the life of every workers’ compensation case. When the carrier seeks to reclassify a client from TTD to TPD, we review the IME report, compare it to the treating physician’s independent clinical findings, and prepare to challenge the reclassification at a hearing if the medical evidence supports our client’s position.
We also evaluate light-duty offers to determine whether they are consistent with the client’s medical restrictions and whether the offered wages accurately reflect the client’s earning capacity. A light-duty offer that looks reasonable on paper may not be appropriate for a specific worker’s medical situation. The details matter, and we review them carefully.
