John R. Christiansen, MD, is an internal medicine physician in Oklahoma City who accepts new patients and focuses on preventive care and chronic disease management for adult patients. He practices within a clinic-based model and is affiliated with established local healthcare networks, making him one of several options for primary care in the metro area.
Christiansen's practice is primary care internal medicine, which means he handles the full range of adult patient needs: initial diagnosis, ongoing management of conditions like hypertension, diabetes, and hyperlipidemia, preventive screenings, medication management, and referrals to specialists. Internal medicine differs from family medicine in scope and patient population; family medicine typically includes pediatric and obstetric care, while internal medicine focuses exclusively on adults. His practice is clinic-based rather than hospital-employed, which shapes visit structure and continuity.
A first appointment with Christiansen typically includes a full history and physical, review of medications and past medical records, and preventive screening recommendations based on age and risk factors. New patients should arrive with insurance cards, photo ID, and a list of current medications or supplement bottles. If you are established elsewhere, request records be sent ahead; without them, the appointment will be longer and may include repeat testing.
Pricing operates under insurance-based billing. Copays for established-patient visits typically range from $15 to $40 depending on your plan; new-patient visits are usually higher, often $40 to $75. Confirm your specific copay with the clinic before your first visit, as plans vary widely. Out-of-pocket costs for preventive services (routine physicals, screening labs covered under the ACA) should be zero if your insurance is current, but specialty testing or procedures beyond the preventive bundle incur separate charges.
Oklahoma City has a multilayered primary care market. OU Health operates the largest academic system and employs hundreds of primary care physicians; their providers typically have next-available appointments within 2 to 4 weeks for new patients. Integris Health runs a competing major network with similar availability. Community Care, a federally qualified health center, offers sliding-scale fees and serves uninsured and underinsured patients, with appointments sometimes available sooner but often with longer wait times once you arrive.
Christiansen's position as an independent or small-group clinic-based internist typically offers middle-ground logistics: appointment slots may open sooner than large academic systems (1 to 3 weeks for new patients), but his practice size means less institutional backup if he is unavailable. Choose Christiansen if you want continuity with a single physician and clinic-based efficiency. Choose OU Health or Integris if you value access to on-site specialists and imaging. Choose Community Care if cost is the primary driver and you are uninsured or underinsured.
Christiansen is well-suited for adults seeking an ongoing relationship with a primary care physician, especially those with chronic conditions requiring regular monitoring and med adjustments. Established patients who value seeing the same doctor tend to report better outcomes with independent practices because scheduling becomes easier once the relationship is known.
The practice is not appropriate for acute episodic illness if you need same-day care; use urgent care for that. It is not a good fit if you need pediatric care or prenatal services. It may not be ideal if you require frequent specialist referrals and prefer integrated on-site access, as clinic-based internists refer out to specialists rather than employ them.
Arrive 15 minutes early to check in. Bring insurance card, photo ID, medication list, and any recent test results from previous providers. The appointment itself usually lasts 30 to 45 minutes. Expect the physician to take a detailed history, perform a physical exam, and order baseline labs if you have not had recent work done. If you are here for a specific complaint (new joint pain, shortness of breath), the visit will focus on that, but a true new-patient visit also includes preventive counseling.
After the visit, you may be asked to schedule follow-up labs or a follow-up appointment in 2 to 4 weeks. If chronic disease is identified, you will receive a treatment plan and medication prescriptions; refills can usually be requested by phone or patient portal.
Verify current hours with the clinic directly, as scheduling can shift seasonally. Most independent internal medicine practices in Oklahoma City operate Monday through Friday, 8:00 AM to 5:00 PM, with limited Saturday hours or none. Parking is typically clinic parking lot only; on-street parking is not standard for Oklahoma City medical offices.
Christiansen practices in Oklahoma City proper, not a suburb, which means reasonable access from most parts of the metro. If you are in the northwest or southern suburbs, allow 20 to 30 minutes travel time during business hours.
A primary care relationship with John R. Christiansen addresses the most common healthcare need in Oklahoma City: ongoing management and preventive screening for working-age and retired adults. His clinic-based model fills a gap between large institutional systems and urgent care, appropriate for patients who value continuity and a straightforward, appointment-driven approach.
