Same-Day Appointments

are held in reserve each day for sick patients. Do not use email or our online form if you are sick; call us and use extension 302 to book an appointment right away.

Be sure to bring your current insurance card and a method of payment (cash or credit card) for your copay.

(610) 363-0100 x302

For this matter, a phone call is essential to ensure an appointment is booked quickly. Please do not use email or our online form, as these are checked less frequently.


Well Visits

such as an annual physical, a routine gynecological visits, or sports/college/driver physicals. Scheduling these appointments can be done conveniently by email or with our online appointment request form.

Note: All patients MUST bring to their appointment their current insurance card and a method of payment (cash or credit card) for their copay, or the appointment may need to be rescheduled.

To be referred to a specialist, it is our policy that patients must be current on their PCP follow-up visits before we can renew specialist referrals. In general, this means you must have been seen in our office for your medical condition within the past year or less. For new referrals or new medical concerns, patients must see their Primary Care Physician to determine if further evaluation by a specialist is needed before issuing a new referral. Exceptions to this rule are ob/gyn and oncology appointments. 

Note: We do not routinely refer to chiropractors. Not all chiropractic treatment options are FDA approved or recommended by us, therefore we ask that, for your best health and safety, you see your CMMD & Associates provider before any chiropractic referrals can be authorized


To request a referral:


  • Log in to your account on the Patient Portal >

  • Click on "Your Menu" on the upper left hand side, and select "Request Referral/Pre-cert".

  • Choose the provider who will be authorizing the request (should be the PCP you selected as your primary provider)

  • Fill in the name of the specialist (First and Last) and their specialty (e.g., dermatology, gastroenterology, ophthalmology, etcetera)

  • Fill in the reason that you are seeing a specialist (e.g. glaucoma, hyperthyroidism, fracture, etc.); please be as specific as possible.

  • Use the comments box to provide additional details requested (including your insurance plan and ID number, address and fax of the specialist, the date of your appointment (if scheduled), and procedure or diagnosis code, if needed)

  • Click "Send" to submit your request.

Once the referral has been submitted, it will be routed directly to your provider for approval, then routed to our referral specialist. Please allow up to 48 hours for processing. The specialist's office will receive the referral electronically through the Navinet insurance system.

Patients can also call (610) 363-0100 #215 to reach our referrals specialist.


Refill requests must come directly from your pharmacy. Please call your pharmacy and ask that they submit an electronic request. Allow 48 hours for your request to be processed. Contact your pharmacy early in the day, and early in the week. Requests received after 3:00pm will not be addressed until the next business day, and may take up to 48 hours for completion. Read more about our refills policy >

To ask a question or check the status of a refill, please email

or call (610) 363-0100.


If you require a refill of a controlled substance, gather the required information below:


Patient Full Name

Patient Date of Birth

Primary Provider/Practitioner at CMMD & Associates

Drug Name (from the bottle, please)

Dose (from the bottle, please)

Times taken per day (from the bottle, please)

Pharmacy Name, Street Address, Phone

Does your Insurance allow 90-day supplies?

Is this refill needed urgently?

Please note that we are unable to call in or authorize refills of controlled medications after hours or on weekends. Due to tightened DEA regulations, medications such as narcotics, anti-anxiety medications, and ADD medicines will only be refilled Monday-Friday, 9 am to 5 pm. Please check your medication quantities carefully before the end of the week. Please note that if you are on a controlled substance for ADD (Adderall, Ritalin, Vyvanse, Concerta, Focalin and others) you MUST be seen at least every THREE months in order for refills to be authorized.


Send this information to

or call (610) 363-0100

or enter it into the form below:


A reminder: this form is ONLY for controlled substance refill requests. For all other refills, please contact your pharmacy and ask that they send us an electronic request.

See us first! Our see-us-first policy is designed to save you time and money. We can often diagnose and treat conditions right here in our office, where a specialist's co-pay may be higher and the appointment may take longer to schedule. We can also save you a visit to the wrong specialist (this happens all the time!) and point you to a specialist who has an excellent reputation of care. Make an appointment here and let us guide you!



For this matter, the online patient portal is best.

Some medications must be pre-authorized for insurance coverage.

Please use our secure Patient Portal to send a General Portal Message to your provider, including your prior authorization request and any supporting information. 

Note that these requests can take 48-72 hours due to communication with an insurance company; we will contact you as soon as we have an update, but feel free to follow up in your patient portal or with a phone call.

We love to hear from you!

All practitioners at our office welcome you to send them a secure Patient Portal message for non-urgent communication about your care, keeping in mind that:

  • We respond to messages during the course of our normal workday.

  • We do our best to respond to all messages within 48 hours. If you need an answer faster, a portal message may not be the best method; please call the office.

  • If your message goes unanswered for more than 48 hours, please call the office; it may not have been successfully delivered.

Provider Email Addresses:

For matters that do not relate to medical matters or your chart, such as feedback or questions about appointments, we welcome your emails. (Note: Discussions about personal medical information should be reserved for secure Patient Portal messages instead. Thanks!)

If you have not received a call or portal message with test results in the timeframe your provider estimated they would be available (usually 14 days), please do not hesitate to contact us by phone or portal and we will investigate any results that may be in the queue to be sent to you. Note: we cannot discuss test results via email.
