Areas of Specialty

Infusion Therapy

Our in-house infusion suite offers patients a comfortable, relaxing environment, where our specially-trained infusion nurse administers therapy for the treatment of many diseases.

These treatments are typically covered by most insurance companies, however, co-pays, co-insurance and deductibles are applied based on each insurance plan. Financial aid through foundation programs are available if the patient meets their criteria.

Policies & Procedures

Insurance & Referrals

Patients are responsible for understanding their insurance plan and are expected to pay all co-pays, co-insurance and deductibles. Please contact your insurance carrier to ensure we are an "In-Network" provider prior to your first appointment. If your insurance changes at any time, we ask that you notify our office before your next appointment to ensure we accept it and whether or not it requires a referral.

If your visit requires a referral, our office will contact your PCP approximately one week prior your appointment. If we encounter any issues or a referral is denied, we will contact you to reschedule.

Missed Appointments & No-Show Fees

We understand that plans change and emergencies happen, but we kindly ask that you contact our office prior to 24 hours before your scheduled appointment to reschedule or cancel. Our office will either call, email or text your appointment reminder based on your selection, however, it is still the responsibility of the patient to note the appointment at the time they originally schedule it. We cannot be held responsible for being unable to reach you without accurate contact information provided to us.

Patients who miss their scheduled appointment and do not contact our office ahead of time or immediately thereafter with a valid reason (i.e. hospital visit or illness), a $25.00 no-show fee may be applied to your account and will be collected before any future visits.

Prescription Refills & Narcotic/Controlled Substance Agreement

Refill requests should be discussed at the time of your appointment. If you will need a refill before your next visit, please contact our office directly at least 7-10 days before you run out of medication. This allows us time to receive and process your request in a timely and reasonable manner.

Patients needing narcotics to help with their pain will be evaluated on an individual basis. For patients who are approved, a Narcotic/Controlled Substance Agreement is required in order to maintain a safe, compliant treatment plan.

New Patient Paperwork

Save time and download your paperwork before your first appointment. Complete all the sections and simply bring it with you the day of your appointment along with a Photo ID and insurance card.
