AMA Permanent Impairment/WPI (California) (California)

Postby Hardluckjuan on Fri Sep 08, 2017 10:36 am

My AME report reads as follows: "Using the current examination, the left shoulder is 11% upper extremity, and the right is 9% with WPI =12%. Cervical DRE II = 5%. Lumbar ROM WPI = 36%. Spinal WPI = 43%. Knee impairment = 44 %, based on a poor result on the right and a fair result on the left, using the table 17-35. The total WPI is 75%.

Where may I find the method used to arrive at the sum of 75%?
Should I assign the 44% knee impairment a 20% WPI as the report does not list a WPI for the knees only the impairment?

Check with your local I&A officer and have the DEU rate the report.

You shouldn't be doing anything with the WPIs as they are meaningless in the context provided. Each body part is rated separately and then combined.

Your summary does not make sense, does not describe the factors of apportionment for each body part and does not explain the rationale so a rater could in fact assure the rationale complied with the AMA Guides as to the WPI assigned being correct.

SO I second Vampire's motion. Get the DEU to rate it.
