Please let us know at the beginning of the session if we need to devote some of our time to discussing or filling out forms or write notes or letters. We advise you to please fill out forms to the best of your ability prior to the session so that we may use our time more efficiently and focused on you. Letters, forms, record reviews, and interactions with outside agencies requiring significant attention outside of scheduled appointment times, will be subject to fees determined on a time for service basis. Please feel free to inquire about fees.
This excludes activities deemed by the provider to be clinically essential, such as interacting with other clinicians directly involved in your care, and executing routing duties such as providing refills, filling out routine authorization’s requests, and brief clinically-focused return of patient phone calls.
We provide refills of your medications at the time of your office visit. Please bring your medication list with you to each appointment to ensure quality of service is provided.
Please be sure to give us at least 72 hours’ notice on all refill requests. Chronic or long-term medication refills require an office visit before they may be refilled.
In other cases, we request that you contact your pharmacy for medication refills. The pharmacy will fax a request to our office with all pertinent information. You are responsible to notify the office at the time of your appointment if you are running out of medication so that we can avoid medication shortages.
If you have mail-in series, you are responsible to mail the forms and prescriptions after we fill them out to avoid any confusion. Medication refills must be taken care of during your appointment, under unforeseen circumstances if you run out of medicines; please contact the office during regular business hours. We will be happy to refill your non-controlled medications if you have a scheduled follow-up appointment or will schedule you with the next available provider.
Controlled lost/stolen prescriptions may require a police report and will only be refilled if clinically safe. Refills do not guarantee medication coverage, please speak to your pharmacy regarding coverage
