Dr. Jack B. McCallie in Chattanooga: Internal Medicine for New and Established Patients
Dr. Jack B. McCallie runs an internal medicine practice in Chattanooga that serves both new patients and those seeking ongoing primary care management of chronic conditions. Internal medicine providers focus on diagnosing and treating adult diseases across multiple organ systems—the medical home for adults before any referral to specialists becomes necessary. McCallie's practice is structured to handle continuity care rather than episodic urgent visits, making it a baseline option for anyone seeking a long-term primary care relationship in the city.
What Dr. McCallie's practice actually offers
McCallie operates as a general internal medicine physician. The practice handles preventive care (annual exams, screening), management of common chronic illnesses (hypertension, diabetes, high cholesterol, COPD), acute non-emergency illness, and coordination with specialists when needed. Internal medicine differs from family medicine primarily in scope: family medicine includes pediatric and obstetric care, while internal medicine concentrates on adults only. This specialization means McCallie's training and daily practice focus entirely on adult physiology and disease patterns.
The practice accepts new patients and does not operate on an emergency or walk-in basis. Appointments are scheduled in advance, typically for 15 to 45 minutes depending on complexity. Established patients receive continuity, meaning the same physician reviews your chart across visits and maintains a longitudinal record of your health trajectory.
Insurance and cost structure
McCallie's office accepts Medicare, most commercial insurance plans, and Medicaid. Patients should verify their specific plan before the first visit; some plans require referrals from another physician before seeing a specialist or non-primary-care internal medicine doctor, though this depends heavily on whether McCallie is in your network as a primary care provider or a specialist.
Out-of-pocket costs depend on your plan's structure (copay, deductible, coinsurance). A typical office visit for an established patient runs 15 to 20 minutes and may cost $20 to $50 if you have a copay; uninsured patients should call ahead to ask about cash-pay rates, which often differ significantly from insurance allowances.
How this practice compares to other Chattanooga primary care options
Chattanooga's primary care landscape includes internal medicine physicians, family medicine doctors, and nurse practitioners at various independent practices, urgent care clinics, and federally qualified health centers (FQHCs). The key distinction: internal medicine physicians have completed a three-year residency in internal medicine alone, whereas family medicine doctors train in both adults and pediatrics. For an adult with multiple chronic conditions, internal medicine specialization may mean deeper expertise. For a family with children, family medicine provides one-stop care across all ages.
Independent practices like McCallie's differ from larger multispecialty groups or hospital-affiliated clinics in scheduling flexibility, continuity, and patient volume. Smaller independent practices often have shorter wait times for appointments and longer individual visit time, but may lack on-site lab or imaging capability. Hospital-affiliated practices (such as those within Erlanger or CHI Memorial networks) offer faster specialist referrals and same-system electronic records but may carry higher administrative overhead and longer appointment wait times due to patient volume.
For patients without an established primary care home, internal medicine practices offer the stability of longitudinal care; for those needing urgent non-emergency care (strep throat, minor infection), urgent care clinics across Chattanooga provide same-day or walk-in options at higher cost but faster service.
Who this practice suits and who it does not
McCallie's practice suits adults aged 18 and older seeking ongoing primary care, especially those with multiple chronic conditions or complex medication regimens who benefit from continuity with one physician. New patients transitioning to Chattanooga often build a primary care relationship here. Established patients value returning to the same doctor who knows their history.
This practice does not suit those needing immediate care (go to an urgent care clinic or ER instead), parents seeking pediatric care (choose a family medicine doctor), or anyone requiring specialist consultation on the same visit (internal medicine is the referral source, not an emergency conduit).
What the first visit involves
New-patient appointments typically last 30 to 45 minutes. You will complete a health history form covering your medical background, medications, allergies, family history, and social history. Dr. McCallie or a nurse will review this, take vital signs, perform a physical examination, and discuss your health goals. Blood work or other screening may be ordered if indicated. At the end, you will receive a plan for follow-up, prescriptions if needed, and referrals to specialists if appropriate. Bring your insurance card and photo ID.
Hours, location, and parking
McCallie's practice operates during standard business hours, Monday through Friday. Specific hours and parking details should be confirmed by calling ahead, as independent practices adjust schedules seasonally and may have limited on-site parking. Chattanooga's downtown medical corridor and surrounding neighborhoods offer street and lot parking near most physician offices.
Dr. Jack B. McCallie's practice provides the continuity and depth that internal medicine offers, anchoring adult primary care for a subset of Chattanooga patients who prioritize ongoing relationship with one physician over convenience of walk-in access.
