My suggestions - only suggestions and not to be construed as legal advice - no attorney-client relationship of any sort is created here:
1) Make application - again maybe? - in writing to this master "Board". Send it with return receipt and save copy
2) Request - in writing with return receipt and save copy - that these folks put their denial of your application to you in writing.
3) Suggest to them - in writing with a return receipt and save copy - that they are engaging in an illegal restraint of trade and request that they reconsider their denial and notify you, in writing, within 10 business days of their decision. Ask, in wiriting and politely, for 1) the identity of the attorney who has rendered this legal opinion to them or 2) the name of the physician who came up with this excuse and which law school he graduated from, and the date of graduation from said law school (certainly these good folks aren't practicing law without a license). Also send this letter with a return receipt and copy it (note in the letter that you have copied it) to the Texas Office of the Attorney General and the Texas State Board of Insurance ( addresses in blue pages of phone book or call info for Texas state government)
4) Educate your patients, as consumers of health care in the state of Texas, to the fact that they are being denied the benefits of your care and you believe that to be due solely to the circumstances as you have described them - so that they may also write to their carrier and request that you be added to the insurance lists - let them know they may copy their letters to the State Insurance Board and Attorney General under consumer complaints and that they are free to so note to their carriers.
5) Ask these doctors, in writing, to define for you "own your own practice". Do they mean that all patients you see must be a physician's patients? Do they mean a doctor must be on the premises lease ? Do they mean a physician must own the real property and equipment ? So can a physician's wife also own the "practice" ? So, is it that a non-MD wife can own a practice but not a NP ? Ask them if you incorporate will they then put you on the panels ? Ask them to, please, point out to you which part of the NPA their lawyer is of the opinion mandates that all practice sites be "owned" by an M.D. Are they requiring that 100% be physician owned - or are they allowing for community property ownership ?
5) Do the same process - applying and getting everything in writing - with each insurnce carriers individually - in addition to making the common application to this local "Board" of docs who appear to be practicing law without a license.
6) Apply for and obtain inclusion in Texas medicaid + federal medicare programs. These should not go through your local good old boys club. But if they have a say about these also - file a complaint - in writing, RRR, nad save copy - with the US Federal Government Dept. of Health + Human Services and the State of Texas Dept, of Helath + Human Services.
7) When you have all of this in writing, contact me and we'll see if I can refer you to an attorney who may be willing to deal with this as a class action legal issue - or we might request an opinion from the Texas Attorney General, depending on the elections out come. You might also do some work to find out which legislators are sympathetic to NP practice - state APN association may be able to help with this.
8) As for the on-site supervision - there is a provision in the NPA which no physician has yet used - allows for them to claim a hardship is created by having to supervise on site - so even that is not absolutely necessary. However, what MD wants to rock the boat when his buddies are racking in big bucks for "supervising" want-a-be doctors.
9) Consider that the NPA allows us to provide services to poor patients with less supervision that we are required to have in order to provide the same care to rich patients in private practice offices. Obviously, the BNE + BME is of the opinion that rich folks here deserve better care than our indigent, medically underserved or this "collaborative practice" joke must be simply about money.
10) Consider relocating to one of the 11 states that has either 1) a less financially obsessed medical association lobby or 2) a more educated electorate than Texas (my home state which I love but too old to wait around for it to change).
Best of wishes.
