MAC Antitrust Policy

The American Vein & Lymphatic Society (AVLS) is a premier nonprofit association for physicians and allied health professionals dedicated to the diagnosis and treatment of venous and lymphatic disease. As the industry’s leading experts, the AVLS seeks to improve the standards of medical practitioners, the quality of patient care, and the level of assistance practitioners can access. Health professionals can use MAC as an online community forum to exchange medical knowledge and health

MAC has a strict policy of compliance with federal and antitrust laws. The antitrust laws of the United States prohibit agreements, combinations, and conspiracies that restrain trade among competitors. MAC members may be considered to be competitors for purposes of antitrust challenges even if their practices are not in the same geographic areas.  The penalties for violations of the antitrust laws are severe for medical societies and their members.

In all MAC activities, each member shall be responsible for following the association’s policy of strict compliance with the antitrust laws. The MAC Moderators and committee chairs shall ensure that this policy is known and adhered to in the course of activities pursued under their leadership.  Antitrust compliance is the responsibility of every MAC member and MAC Moderator.

General Antitrust Compliance Principles

MAC will not become involved in the competitive business decision of its members, nor will it take any action that would tend to restrain competition. MAC is firmly committed to the principle of competition served by the antitrust laws, and good business judgment demands that every effort be made to assure compliance with all applicable federal and state antitrust laws and trade regulations.

MAC members in separate practices cannot come to understandings, make agreements, or otherwise concur on positions or activities that in any way tend to raise, lower, or stabilize prices or fees, allocate or divide up markets, or encourage or facilitate boycotts. Individual MAC members must make decisions regarding the amounts they charge for their services and other terms of dealing with patients, vendors, and third-party payors on their own and without consultation with their competitors or MAC.

The antitrust laws are complicated and often unclear. If any member is concerned about being in a “gray area,” the member should consult with an antitrust attorney. If the conversation among competitors at a MAC meeting or on mac turns to antitrust-sensitive issues, participants should discontinue the conversation until legal advice is obtained or leave the meeting or mac immediately.

Discussions of pricing or boycotts as part of MAC-scheduled programs, at MAC-sponsored meetings or on mac could implicate and involve the MAC in extensive and expensive antitrust challenges and litigation. In addition, the U.S. Supreme Court has determined that an association can be held liable for statements or actions in antitrust-sensitive areas by volunteer leaders who claim to speak for the association, even if they are not authorized to speak in that area. Directors and officers of must, therefore, make clear whether they are speaking in their official capacity when they address such issues; by contrast, if they are making personal remarks outside of the MAC setting, the speaker should clearly state that he or she is speaking for him or herself, and not on behalf of the MAC.  No MAC members, including MAC Board members, may purport to speak on behalf of MAC without the prior written consent of the AVLS President or Executive Director.

Specific Rules of Antitrust Compliance

  1. MAC activities shall not be used to bring about, or attempt to bring about, any understanding or agreement, written or oral, formal or informal, expressed or implied, among competitors concerning prices or fees, terms or conditions of sale, discounts, territories or customers. For example, any agreement by competitors to “honor,” “protect,” or “avoid invading” one another’s geographic areas, practice specialties, or patient lists would violate the law.


  1. MAC activities and communications shall not include discussion or actions, for any purpose or in any fashion, of prices or pricing methods or other limitations on either the timing of services or the allocation of territories or markets or customers in any way. For example, MAC members cannot come to understandings, make agreements, or otherwise concur on positions or activities that are directed at fixing prices, fees, or reimbursement levels. Likewise, MAC members cannot collectively make agreements as to whether they will or will not enter into contracts with certain managed care plans. Even if no formal agreements are reached on such matters, discussions of prices, group boycotts, or market allocations followed by parallel conduct in the marketplace can lead to antitrust scrutiny or challenges. Members may, however, consult with each other and freely discuss the scientific and clinical aspects of the practice of medicine.


  1. MAC shall not undertake any activity that involves exchange or collection and dissemination among competitors of any information regarding prices, pricing methods, cost of services or labor, or sales or distribution without first obtaining the advice of legal counsel when questions arise as to the proper and lawful methods by which these activities may be pursued. For example, caution should be exercised in collecting data on usual and customary fees, managed care reimbursement levels, workforce statistics, and job market opportunities. While the mere collection of data on such matters is permissible if certain conditions are met, antitrust concerns may arise if the data become the basis for collective action.

Any violation of the antitrust policy will be brought to the attention of AVLS staff who will deal with it in a timely and appropriate manner. AVLS will consult with legal counsel when questions arise as to the manner in which the antitrust laws may apply to the activities of MAC.

In general, MAC activities and communications shall not include any discussion or action that may be construed as an attempt to: (1) raise, lower, or stabilize prices; (2) allocate markets or territories; (3) prevent any person or business entity from gaining access to any market or any customer for goods or services; (4) prevent or boycott any person or business entity, including managed care organizations or other third-party payors, from obtaining services freely in the market; (5) foster unfair trade practices; (6) assist in monopolization; or attempts to monopolize, or (7) in any way violate applicable federal or state antitrust laws and trade regulations. The actual purpose and intent of MAC’s policies and programs are important in this regard. They cannot be aimed at accomplishing anti-competitive objectives.

If you see what you believe is a violation of these rules in any of the MAC forums, please notify your community MAC Moderator by messaging them through the online platform.
