In Southwest Virginia, physicians who admit the majority of their patients to an HCA Virginia facility are eligible to participate in our referral service. There is no charge for this online referral service, and physicians are not charged a fee to participate in it. Physician participation in our online referral system is strictly voluntary. Physician names are provided on a rotating basis as they meet your needs. If you have an insurance plan such as an HMO or PPO, itís your responsibility to determine if the physician practice participates in your plan.
