Your impairment rating can determine how long you receive permanent partial disability (PPD) checks and how much they total over time. Even a small percentage swing may change your payout by thousands.
How impairment ratings work
After you reach maximum medical improvement, your authorized treating physician assigns a percentage using the AMA’s Guides to the Evaluation of Permanent Impairment. Georgia law then ties that percentage to a schedule of body parts. For injuries not listed, the “body as a whole” applies and equals 300 weeks.
How Georgia calculates your PPD
PPD is a two-step formula. First, convert the impairment rating into weeks. Second, multiply those weeks by your weekly compensation rate. Here’s what you need to know:
- Weeks owed: Rating % × statutory weeks for that body part.
- Weekly amount: Two-thirds of your average weekly wage (AWW), capped at $800 for injuries on or after July 1, 2023.
- Timing: PPD starts only after temporary total (TTD) or temporary partial (TPD) benefits end.
Your AWW usually comes from your average earnings during the 13 weeks before the injury. If your injury occurred before July 1, 2023, the cap may be lower under the statute.
Examples that make the numbers clear
A 10% rating to an arm equals 10% × 225 weeks = 22.5 weeks. If your AWW is $900, your weekly rate is $600 so you receive about 22.5 × $600 = $13,500. If the same injury is rated 12%, you get 27 weeks of pay or $16,200 total. That two-point increase adds $2,700.
Georgia’s schedule fixes the maximum weeks by body part. A thumb is 60 weeks, a little finger is 25 weeks, a hand is 160 weeks, a leg is 225 weeks and the body as a whole is 300 weeks. Your rating slices the maximum to produce the payable weeks. Even small differences in the rating can change how much you receive and what a potential settlement is worth.
What drives the rating you receive
Your treating physician applies the AMA Guides to evaluate permanent loss of function. Georgia requires the rating to reflect objective medical findings such as test results, imaging and range of motion. A Functional Capacity Evaluation may also help measure your limitations but the authorized physician decides the final percentage.
Documents that influence your payout
Keeping clear documentation can help ensure your benefits reflect your true medical condition and earnings. Here’s what you need to gather:
- Medical findings: Objective test results and treatment notes.
- Edition and method: The AMA Guides version used for the evaluation.
- Accurate wage proof: Pay records that confirm your AWW.
- Injury category: Whether your rating applies to a scheduled part or to the body as a whole.
Georgia’s PPD statute sets fixed weeks and calculates payments at two-thirds of your AWW, subject to state limits. Because each percentage point changes the total number of payable weeks, even minor adjustments in your impairment rating can raise or lower your overall benefit amount and affect your case’s settlement value.
What you can do next
If you believe your impairment rating is too low or your benefits were calculated incorrectly, you may want to discuss your case with a Georgia workers’ compensation attorney. An attorney can review your medical records, request a second opinion or challenge the rating before the State Board of Workers’ Compensation.
Having legal guidance can help protect your rights, confirm the accuracy of your benefits and ensure you receive the full compensation the law allows.
