Your PTP/Primary Treating Physician is the Dr you saw who treated you, and released you at MMI, IN 2007.
Why are you waiting 3 years later to address this injury ?
Why wasn't the PTP recommending shoulder surgery, at the time you were declared MMI ?
The CA doesn't tell any Dr what to do to treat or release an IW at MMI. The PTP controls the medical in a claim. Not the CA.
''I was originally approved for carpal tunnel and an impingement.'' Ok, and you said you had the CT surgery...
''The MPN had an MRI done, which showed a torn rotator cuff. I was just recently told that by the MPN pain doctor.'' If you are seeing a pain management Dr now, in the MPN, that is your PTP. Why didn't you tell the Dr your AA sent you to about the injuries, including all you claim, shoulder included ? Dr's don't read minds...if you don;t tell, how would he know ? No, you don't file a new claim...you already did file, you said the CTS and shoulder were claimed... only the shoulder hasn't been treated. It may not do any good for surgery to your shoulder at this point. Rotator cuff tears don't heal on their own, however the longer you wait for surgery, the more difficult to repair, if at all.
You can file a complaint with the state bar on your attys actions, or mis actions.
At this point, IMO... try to find an attorney who will take over your claim. That new one will get your file, and notify the current AA and WCAB of your change.
The CA cannot just 'close' a claim, unless like I said, you have not sought treatment for 18+ months. As you have apparently continued to see a Pain Managment Dr, in their MPN, the claim is still open. Based on the info you provide here.
You really need to consult another AA, message boards are not good substitute for valid legal advice. The AA needs your file.
