Navigate Canandaigua Medical Group Like a Local — From the Right Floor to MyChart, Lab, Pharmacy and After-Hours Care

Canandaigua Medical Group in Canandaigua, NY is located at 335 Parrish Street and is part of F.F. Thompson Hospital within UR Medicine Thompson Health. The building brings adult primary care, pediatrics, OB/GYN, laboratory drawing and pharmacy services together near Thompson Hospital.

The details that matter are more specific than the street address. Internal Medicine, Pediatrics and OB/GYN have different phone numbers and hours; the building is billed as a hospital outpatient department; the lab no longer accepts specimen drop-offs; and nearby urgent care is at a different Canandaigua address.

Current organization: Canandaigua Medical Group became part of Thompson Health in 2018. Today its clinical locations are presented through UR Medicine / F.F. Thompson Hospital. Older records may simply say “Canandaigua Medical Group” or “CMG.”
Emergency warning: MyChart, the primary-care office and urgent care are not substitutes for emergency response. Call 911 for severe chest pain, major breathing difficulty, possible stroke, uncontrolled bleeding, loss of consciousness or another potentially life-threatening emergency.

New-patient path

How to become a Canandaigua Medical Group patient

Thompson Health currently says it is accepting new patients for primary care and OB/GYN and offers an online matching process rather than requiring patients to randomly call multiple offices.

Choose the broad type of care Decide whether you need adult primary care, pediatric care or OB/GYN. This determines which Canandaigua Medical Group department should review your request.
Check the current provider list Provider panels change. Use the live Thompson Health provider directory rather than relying on an old physician list copied elsewhere online.
Submit the primary-care new-patient request when appropriate Thompson Health says a member of its team will contact new primary-care patients within approximately 48 business hours to help connect them with an appropriate practice and provider.
Keep your insurance card beside you You will need the insurer name, member ID, plan or network name and possibly the name of the PCP currently assigned to you.
Ask whether records are needed before the first visit If you have complicated chronic conditions, recent hospitalization, controlled medications or specialty treatment, ask what records should arrive before the appointment.
Confirm the final office and floor A Thompson Health provider may practice in Canandaigua, Farmington or another Finger Lakes location. Do not assume that every provider shown under Thompson Health practices at 335 Parrish Street.

What to bring to Canandaigua Medical Group

Government-issued photo identification
Current insurance card
Secondary coverage if applicable
Referral or prior authorization if required
Current prescription list with doses
Vitamins and supplements
Medication allergies and reactions
Preferred pharmacy name and location
Recent hospital or specialist information
Home blood pressure or glucose log when relevant

What “On My Way” means

Thompson allows patients to notify urgent care that they are coming. This can help staff prepare and may reduce waiting uncertainty, but it is not a reserved appointment time. Patients are still treated according to clinical severity.

2026 insurance check

Insurance accepted at Thompson Health and why the exact plan still matters

UR Medicine’s affiliate insurance chart was updated in June 2026 and lists many major insurers as participating with Thompson Health and its providers. However, one insurer can sell several networks, and not every product necessarily includes every physician or hospital outpatient department.

Common commercial carriers

Examples on the UR Medicine insurance charts include Aetna, Excellus BlueCross BlueShield, MVP, UnitedHealthcare and other participating networks.

Medicare

Medicare and selected Medicare products from participating insurers appear on the current affiliate listings.

Medicaid

New York State Medicaid and selected Medicaid managed-care products appear on current UR Medicine carrier information.

Other networks

Fidelis, TRICARE, MultiPlan/PHCS, UMR and several other products are represented on UR Medicine’s published charts.

Do not use the insurer name alone. Give both Thompson Health and your insurer the exact plan name, member ID, physician and 335 Parrish Street location.

“My appointment is with [provider] at Canandaigua Medical Group, 335 Parrish Street, which is listed as an outpatient department of F.F. Thompson Hospital. Is this physician and facility in network under my exact plan? What are my copay, deductible and coinsurance, and does a facility fee apply?”

Important cost issue

Why a routine Canandaigua Medical Group visit can include a hospital facility charge

The current UR Medicine listings for Canandaigua Medical Group identify the practice as an outpatient hospital department of F.F. Thompson Hospital. That billing status matters.

Professional charge

This generally relates to the professional service performed by the physician, nurse practitioner, physician assistant or other licensed practitioner.

Facility charge

A hospital outpatient department may bill an additional facility component connected with the hospital resources supporting the visit.

UR Medicine explains that facility charges can relate to

Use of examination or procedure rooms
Medications administered in the clinic
X-rays or other diagnostic tests
Technician or nursing services
Hospital-supported outpatient resources
Other costs separate from the licensed practitioner’s professional fee
This does not mean every patient owes the same extra amount. Your responsibility depends on your insurer’s contract, network, deductible, copay, coinsurance and the actual services provided.

How to estimate the cost before a non-urgent service

Ask the medical office for the service or CPT code A specific procedure code gives the pricing team and insurer a better starting point than a broad description.
Use the Thompson Health cost estimator Enter the planned service and insurance information to obtain an estimate.
Call the insurer Ask specifically about the hospital outpatient facility component as well as the clinician charge.
Save the estimate Keep the estimate and any authorization number in case the final claim differs.

Bills, payment and financial help

How Thompson Health billing works after a Canandaigua Medical Group visit

Check your insurance information at registration An old insurer, member number or assigned PCP can create avoidable claim problems.
Pay the amount due at the visit Thompson’s primary-care financial information says applicable copayments are collected before physician or office laboratory services.
Wait for insurance processing Your insurer determines its allowed amount, payment and your cost-sharing responsibility.
Compare the bill with the explanation of benefits Confirm the visit date, location, provider, professional charges, facility charges and insurer adjustments.
Call before paying a balance you do not understand Ask whether the problem is an insurance denial, missing referral, deductible, non-covered service or facility-fee responsibility.

Published hours: Monday–Friday, 8 a.m.–4:30 p.m.

Financial assistance

Thompson Health offers financial aid for qualifying patients based on income and circumstances, including insured and uninsured patients.

Having trouble paying? Ask about Thompson Health financial assistance and manageable payment arrangements before ignoring the bill. The system specifically directs patients to contact it when they cannot pay in full.
Credit-card caution under New York law: UR Medicine warns that paying medical services with a credit card changes the debt into credit-card debt and may cause the patient to lose some protections that apply specifically to medical debt. Review payment-assistance options before moving a large medical balance to a credit card.

Paperwork tip most patients miss

Canandaigua Medical Group forms, health care proxy and the $15 form charge

Thompson Health’s Canandaigua Medical Group forms page provides information about several documents patients may want to review before meeting a provider.

Health Care Proxy

New York patients can designate a trusted person to make health decisions if they become unable to make those decisions themselves.

Advance directives

Patients can review New York information about accepting, refusing or stopping treatment in appropriate circumstances.

Child medical permission

Parents leaving town can prepare authorization information for another adult who may need to obtain care for a child.

Internal Medicine form fee: Thompson Health currently states that its Department of Internal Medicine charges $15 per form for certain forms that need to be completed when the work is not done during the patient’s office visit.
How to avoid unnecessary form delays: Bring school, work, disability, camp, sports or other forms to the appointment and ask whether the clinician can complete the required portions during the visit. Some forms require a recent examination or specific test before they can be signed.
Open current CMG form information
Accessibility and communication

Need an interpreter or communication assistance?

Thompson Health states that interpretation services can be provided at no charge for patients who do not speak English and for patients who are visually impaired, deaf or hard of hearing.

Tell scheduling which language you use
Request an interpreter before the visit when possible
Tell staff if you use hearing aids
Ask about assisted-listening devices if needed
Do this when scheduling, not after the clinician enters the room. Advance notice gives the office more time to arrange the appropriate communication support.
Local mistakes to avoid

9 Canandaigua Medical Group mistakes that create unnecessary delays

01
Going to 350 instead of 335 Parrish

350 Parrish is F.F. Thompson Hospital. The Medical Group’s main Canandaigua building is 335 Parrish.

02
Calling only the general number

Use the direct department phone once you know whether you need Internal Medicine, Pediatrics or OB/GYN.

03
Assuming office billing is independent

The practice is an outpatient department of F.F. Thompson Hospital, so ask about facility charges.

04
Dropping specimens at CMG

The 335 Parrish lab no longer accepts specimen drop-offs; use the hospital specimen window instead.

05
Showing up Saturday for the CMG lab

The Canandaigua Medical Group draw station is closed Saturday.

06
Assuming “On My Way” is urgent-care reservation

It alerts urgent care that you are coming but does not guarantee a scheduled time.

07
Using an old provider list

New-patient panels change. Check the current provider directory before choosing a physician.

08
Waiting until medications run out

Submit routine refill requests early, especially before weekends and holidays.

09
Bringing paperwork after the visit

Internal Medicine may charge $15 for certain forms completed outside the office visit.
