Nissen Clinic

Dr. Nissen holds medical licenses nationwide and offers in-person appointments in Texas, New York, California, Florida, Illinois, and Massachusetts. He also provides telemedicine visits for patients across the country. Patients in other locations can inquire about house calls or in-office visit availability.

Nissen Clinic does not participate in any insurance networks. The practice provides an itemized superbill after each visit, which patients can submit to their insurance company for potential out-of-network reimbursement. Patients should confirm their out-of-network benefits directly with their insurer before scheduling.

Fees are due upon completion of each visit. Nissen Clinic uses GoCardless, a safe ACH-based direct debit payment system. The practice sends payment instructions before the first session. Patients who need alternative payment arrangements can inquire when scheduling.

Nissen Clinic schedules hour-long appointments. This allows Dr. Nissen to go beyond a brief medication check and address therapy, coaching, and overall wellness in each session. Between appointments, patients can reach Dr. Nissen directly by phone or email.
