Differentiating between GV and GW is your first step. Base Modifier GV or GW Choice on Diagnosis When reporting services your urologist provides to a hospice enrolled patient, "the most important thing you need to pay attention to is the correct modifier to use," says Jane Marks, financial services manager at Anne Arundel Urology in Annapolis, Md. "You also need to pay attention to the diagnosis that is on your claim and whether that diagnosis is related to the terminal illness or not." The diagnoses the hospice submits for its patients affect how you bill and what reimbursement (if any) your urologist will receive. If you know which diagnosis the hospice uses, you'll know whether to append modifier GV (Attending physician not employed or paid under agreement by the patient's hospice provider) or modifier GW (Service not related to the hospice patient's terminal condition). Here's how: "This modifier is not commonly used by a urologist," Marks cautions. "The attending physician is defined as the doctor having the largest role in the determination and delivery of the patient's care. This would more commonly be the PCP [primary care physician] or perhaps oncologist versus a urologist." Alternative: Example: Bill the Hospice Directly in Some Cases When Payments are Denied As a last resort, you can always bill the hospice directly for your urologist's services, and the hospice can bill the payer on your behalf. "It is a good idea to have agreements with some of the hospice providers in your area so if your provider is asked to care for a hospice patient and their insurance carrier will not cover those charges, the hospice will pay the provider directly for their services, usually at Medicare rates," Marks explains.
