Will LLMD/PANS physician be more likely to be covered if daignosis is PANS instead of Lyme?

[MDL]

I am hoping our LLMD will be covered under out of network benefits. I am submitting the claim form to insurance and I noticed that the office used one diagnosis code that is for lyme and one for encephalitis.  Since her positive lyme test was 5 months ago might the insurance refuse to pay even at out of network level if they deem that there is no long-term treatment needed for lyme?  Just wondering if I should ask the office to take the lyme diagnosis off the claim form and stick with encephalitis/pans.
