Need a Primary Care Provider (PCP)?

InstaHealth is accepting new patients for Primary Care at InstaHealth.

Patients can enjoy all the conveniences of an urgent care for family practice. 

InstaHealth is contracted as PCP with Cigna and UHC, which means

patients with these insurances only pay PCP co-pay (not urgent care co-pay) at InstaHealth!

Call or stop by today for your annual well exam, blood work or any other preventative services.

Insurances We Accept

BlueCross BlueShield 

Aetna, Cigna, UnitedHealthCare

Medicare, Medicaid, Amerigroup 

AllSavers, Allied,  Tricare Humana,

Freedom Life Insurance (Cigna)

Manulife Global Excel Management

Plus others...Please call the office for any questions.

Urgent Care vs. ER?

Urgent Care can treat anything from

common illnesses to minor injuries.

Avoid the high-cost, long-wait ER for all your non-life-threatening medical conditions that can be treated at InstaHealth Urgent Care!

We offer Cash-pay Discount for patients without insurance and those with high-deductible insurance plans. Cash-pay only $75 per urgent care visit.
