When a New York work injury leaves lasting damage that will not fully heal, you may qualify for permanent disability benefits. The two main categories are Permanent Partial Disability (PPD) and Permanent Total Disability (PTD), and for many PPD cases the key number is your Loss of Wage Earning Capacity (LWEC). This guide explains what each term means and how it affects your payments.
These benefits apply to injuries that are not handled as a Schedule Loss of Use award, such as injuries to the back, neck, head, or other body systems.
When permanent disability is decided
You are not classified as permanently disabled the day you get hurt. First you treat your injury until you reach maximum medical improvement (MMI), the point where doctors do not expect further significant recovery. At that stage, your condition is assessed for permanent impairment.
If your injury is to a “non-scheduled” body part, such as the spine, the Board uses a classification process rather than the SLU schedule. A Workers’ Compensation Law Judge (WCLJ) reviews the medical evidence, often including reports from your doctor and the carrier’s Independent Medical Examination (IME) doctor, and classifies your disability.
Permanent Partial Disability (PPD), explained
PPD means you have a lasting impairment but can still do some work. This is the most common permanent classification for back, neck, and similar injuries.
For non-scheduled PPD, your ongoing benefit depends on two factors:
- Your medical impairment, and
- Your Loss of Wage Earning Capacity (LWEC) — how much your ability to earn a living has been reduced.
What LWEC means
LWEC is the heart of a non-scheduled PPD case. The judge sets a percentage that reflects how much your earning power has dropped, considering your medical impairment along with factors like your age, education, work skills, and the kind of jobs you can realistically still do.
That LWEC percentage matters for two reasons:
- It influences your weekly benefit amount when you have a wage loss.
- It sets a cap on how many weeks you can collect PPD benefits.
How long PPD benefits last
New York law ties the maximum number of weeks of non-scheduled PPD benefits to your LWEC percentage. As a general guide:
- A higher LWEC (greater loss of earning capacity) allows more weeks of benefits.
- A lower LWEC allows fewer weeks.
The durations range from a smaller number of weeks at the low end up to several hundred weeks at the high end of partial disability. Because the exact schedule and your weekly rate depend on your injury date and wages, the total varies by case. The takeaway is that for most PPD claims, benefits are capped, not lifetime.
Permanent Total Disability (PTD)
PTD means your work injury leaves you unable to do any kind of gainful work, permanently. This is a much higher standard than PPD.
Unlike capped PPD benefits, PTD benefits can continue for life as long as the total disability lasts. Classic examples include the loss of both hands, both legs, both eyes, or a combination, as well as other severe conditions that the medical evidence shows prevent any employment.
Because PTD provides lifetime benefits, carriers often contest these classifications closely, and strong medical evidence is important.
Temporary vs. permanent: clearing up the terms
It is easy to confuse the labels, so here is how they fit together:
- TTD / TPD (temporary): While you are still healing, you may receive Temporary Total or Temporary Partial Disability benefits. These are the “before MMI” benefits.
- PPD / PTD (permanent): After MMI, if impairment remains, you may be classified as Permanent Partial or Permanent Total.
- SLU (scheduled): For arms, legs, hands, feet, fingers, toes, eyes, and ears, a Schedule Loss of Use award applies instead of PPD classification.
So the same worker might receive temporary benefits during treatment, then move into a permanent category once the injury stabilizes.
Disability categories side by side
This table compares the main categories and how long benefits can last. Weekly dollar amounts are illustrative and vary by wages and injury date; the structure of each category is set by law.
| Category | What it means | How long benefits last |
|---|---|---|
| Temporary Total Disability (TTD) | Cannot work at all while healing | Until you improve or reach MMI |
| Temporary Partial Disability (TPD) | Can work but earn less while healing | Until you improve or reach MMI |
| Schedule Loss of Use (SLU) | Permanent loss of use of a scheduled body part | A fixed number of statutory weeks |
| Permanent Partial Disability (PPD) | Lasting impairment, some work possible | Capped number of weeks, tied to your LWEC |
| Permanent Total Disability (PTD) | Cannot do any gainful work, permanently | Can continue for life while the disability lasts |
A note on settlements
A classified PPD or PTD claim can sometimes be resolved through a Section 32 settlement, a voluntary agreement to close out future indemnity and sometimes medical benefits for an agreed sum. Once the Board approves it, it is generally final. For a worker who may need ongoing care, giving up future medical coverage is a serious decision, so it is worth fully understanding before agreeing.
Example: how LWEC shapes a back-injury claim
Picture a worker with a herniated disc in the lower back. The spine is non-scheduled, so an SLU award does not apply. Here is how the permanent side typically unfolds:
- First, treatment to MMI. While healing, the worker collects temporary benefits (TTD when fully out, TPD on reduced light duty). No permanent classification happens yet.
- Then, classification. Once the worker reaches maximum medical improvement, a WCLJ reviews the medical evidence, often the treating doctor’s report against the carrier’s IME report, and classifies the case as Permanent Partial Disability.
- The LWEC number does the heavy lifting. The judge weighs the medical impairment plus age, education, skills, and the jobs the worker could realistically still hold, and sets an LWEC percentage. A higher LWEC means a higher weekly benefit when there is wage loss and more weeks of benefits; a lower LWEC means fewer weeks. For most PPD claims, that means a capped number of weeks, not lifetime payments.
- A different outcome if total. If instead the injury left the worker unable to do any gainful work, that would be PTD, where benefits can continue for life, which is exactly why carriers contest those findings so closely.
