"The pain is worse than the number."

What the pain add-on actually is

Chapter 18 of the AMA Guides addresses pain-related impairment. "The maximum allowance for pain resulting from a single injury is 3% WPI regardless of the number of impairments resulting from that injury."

Three percent. Once. No matter how many body parts.

Where it can be used:

Excess pain with a verifiable condition — pain beyond what would be expected from the documented findings. Persistent radiculopathy after surgery is the classic example.

Well-established pain syndromes without significant organ dysfunction — headache, post-herpetic neuralgia, trigeminal neuralgia, and complex regional pain syndrome. How CRPS is rated.

Associated pain syndromes where the organ-system rating does not capture the added burden.

Where it cannot:

Where the body-system rating already encompasses the pain. Most conventional ratings are built assuming a normal amount of pain for that condition. You do not get paid twice for the expected pain.

Where credibility is not documented.

Where the syndrome is ambiguous or non-verifiable. Fibromyalgia is expressly not ratable under this chapter.

And the hard one: "The add-on for pain cannot be included if the underlying rating for the industrial condition is 0% WPI."

Pain can supplement a rating. It cannot create one. A worker whose strict rating is zero — a successful rotator cuff repair, a resolved trigger finger, a hearing loss below the 25 dB fence — gets nothing from Chapter 18 either.

Where the real argument lives

Not in Chapter 18. In Almaraz/Guzman.

Where the strict rating does not accurately reflect the impairment, a physician may use a different method inside the Guides — provided they give the strict rating, explain why it fails, identify the alternative, and explain why it is more accurate.

That is where a case with disproportionate pain is actually made, and it has to be built before the evaluation rather than requested after it. What Almaraz/Guzman is and what it requires.

And what to make sure is in the record

Activities of daily living, in detail. Several impairment methods are driven entirely by ADL loss — the skin chapter, the brain chapter, and the spinal cord axes among them. Evaluators write down what they are told.

Medication and its consequences, including side effects and gastrointestinal effects — which are compensable consequences in their own right. More.

Sleep disruption — though note § 4660.1(c)(1) bars increasing the rating for sleep dysfunction for post-2013 injuries unless the injury was catastrophic or you were the victim of a violent act. How that exception works.

And describe your limits accurately including the good days. "On a good day I can do X, and then I'm down the rest of the day" is truthful, it is what the evaluator needs, and it cannot be contradicted by a surveillance video. More.
