These providers list this insurance as accepted, but coverage should be confirmed directly with the provider before booking.
Same specialty in cities near Columbus OH — useful if your insurance network extends across the metro.
Columbus OH has hematologists practicing across hospital systems, group practices, and independent clinics. When choosing a hematologist in Columbus OH, the three factors most patients care about are: insurance acceptance, distance from home or work, and patient reviews. Heallexa shows all three on every listing so you can compare without clicking back and forth.
Many Columbus OH hematologists list major insurance plans including Blue Cross Blue Shield, Aetna, UnitedHealthcare, Cigna, Humana, and Medicare. Listings reflect what providers have indicated they accept — always confirm in-network status directly with the office before booking. Out-of-network visits can cost 3–5× more than in-network ones.
Confirm three things: (1) they currently accept your specific insurance plan and network tier, (2) the office location and parking, and (3) typical wait times for new-patient visits.
Many Columbus OH hematologists offer telehealth visits, especially for follow-ups, prescription refills, and consultations. Look for the telehealth badge on each profile.
Every listing on Heallexa is matched against NPI records and state license databases. Credentials, board certifications, and active license status are surfaced on each profile.
Yes. Searching, comparing, and contacting Columbus OH hematologists on Heallexa is 100% free for patients. We don't charge booking fees or sell your search data.
