First thing is--what diagnotics codes are you rated under for back strain and arthritis?

Degenerative arthritis is under DC 5003 and rates either 10 or 20% based on X-Ray findings, but can be rated on range of motion. Lumbar strain is DC 5237, and is rated under the General Rating Formula for Diseases and Injuries of the Spine. IDS is DC 5243 and rates under either the general formula or the IDS formula with incapcitating episodes. DC 5241 is spinal fusion.

Second thing--ask the doctor who did the surgery. I think what you want to claim is 5241 spinal fusion and/or IDS 5243, either will be rated primarily on range of motion (general formula).

Will the surgeon write a letter explaining what he did and why it was necessary? That, plus your treatment records and MRI results (both the pictures and the radiologist's report) should be added to your claim--this is where you can ask to change your lumbar (back) strain to spinal fusion and/or IDS based on your diagnosis from your surgeon.

with your treatment records, MRI and (hopefully) IME from surgeon, you may not need a C&P--however, since you've had surgery I wouldn't let them rate you based on the pre-surgery C&P.

I said MRI, assuming you have them pre-op, but if you have anything post-op (MRI, x-rays) I'd add them as well.

Anyway, that's what I'd do.
