Coding is simply how the doctor or doctors explain your situation and/or illness to the insurance company. It determines what insurance you have and how they view your medical conditions. Pain meds are the hardest to have a doctor prescribe and how they determine your need for controlled substances. Lyme disease in its chronic stages as I have experienced is a pain filled internal neurological condition. The only thing that relives it is an anti anxiety pill. If not, I get internal tremors 24/7. The tramadol is for advanced fibromyalgia which no exercise will completely eliminate.
It’s a tough unrecognized disease and yes the states where you live can control your meds.

I am really sorry about what is happening to you. I have been taking Tramadol for 3 or 4 years. I live in California
You need to get your doctor to strongly advocate for you. He needs to document why you still need the Tramadol. Don't just give up.
