I'd be very surprised if the PTA's at GP offices could actually bill for PT services. They may be able to bill under a medical CPT code, but probably not PT. Unless IL's practice act is pretty weak. Most states require that PTA's only operate under the guidance of a licensed PT, not an MD. I know of many ortho clinics that use ATC's as physician extenders. Actually the NATA is actually pushing this role for athletic trainers pretty hard. In these settings they do the patient screening, measurements, and prescribe exercises, but they do not bill under PT codes. Or at least they are not supposed to. One of the major sports med groups in Indy is currently being investigated for violating this.
In Missouri (not IN however) it is illegal for physicians, chiropractors, etc to advertise that they offer PT unless there is a licensed PT there. However they are not allowed to have a financial interest. I am not sure if they are allowed to do this if they disclose it though...I'd have to look it up. Again, you would have to check your state's laws regarding whether it is legal or not to own a PT practice as an MD, but I know for a fact that in several states it is illegal.
Actually I just found it. It is MO Revised Statute 334.253. It states:
Physicians prohibited referral to certain physical therapists, when, financial relationship, defined--exceptions, effective when.
334.253. 1. A physician may not make a referral to an entity for the furnishing of any physical therapy services with whom the physician, physician's employer, or immediate family member of such referring physician has a financial relationship. A financial relationship exists if the referring physician, the referring physician's employer, or immediate family member:
(1) Has a direct or indirect ownership or investment interest in the entity whether through equity, debt, or other means; or
(2) Receives remuneration from a compensation arrangement from the entity for the referral.
2. The following financial arrangements shall be exempt from disciplinary action under this section:
(1) When the entity with whom the referring physician has an ownership or investment interest is the sole provider of the physical therapy service within a rural area;
(2) When the referring physician owns registered securities issued by a publicly held corporation or publicly traded limited partnership, the shares of which are traded on a national exchange or the over-the-counter market, provided that such referring physician's interest in the publicly held corporation or publicly traded limited partnership is less than five percent and the referring physician does not receive any compensation from such publicly held corporation or publicly traded limited partnership other than as any other owner of the shares of such publicly held corporation or publicly traded limited partnership;
(3) When the referring physician has an interest in real property resulting in a landlord-tenant relationship between the physician and the entity in which the equity interest is held, unless the rent is determined, in whole or in part, by the business volume or profitability of the tenant or is otherwise unrelated to fair market value;
(4) When the indirect ownership in the entity is by means of a bona fide debt incurred in the purchase or acquisition of the entity for a price which does not in any manner reflect the potential source of referrals from the physician with the indirect interest in the entity and the terms of the debt are fair market value, and neither the amount or the terms of the debt in any manner, directly or indirectly, constitutes a form of compensating such physician for the source of his business;
(5) When such physician's employer is a health maintenance organization as defined in subdivision (6) of section 376.960, RSMo, and such health maintenance organization owns or controls other organizations which furnish physical therapy services so long as the referral is to such owned or controlled organization and the physician does not also have a direct or indirect ownership or investment interest in such organization, physical therapy services or the health maintenance organization and the referring physician does not receive any remuneration as the result of the referral;
(6) When such physician's employer is a hospital defined in section 197.020, RSMo, and such hospital owns or controls other organizations which furnish physical therapy services so long as the referral is to such owned or controlled organization and the physician does not also have a direct or indirect ownership or investment interest in such organization, physical therapy service, or the hospital and the referring physician does not receive any remuneration as the result of the referral.
3. The provisions of sections 334.252 and 334.253 shall become effective January 1, 1995.
As for a PT/MD practicing both...do you really think that you would have time to do both? Maybe as a PMR doc, but you would still probably be delegating. It would probably be much less lucrative to practice PT part time and medicine the other part. .
