Dr. Johannes Duplooy in Chattanooga: Internal Medicine with Extended Appointment Hours
Dr. Johannes Duplooy operates an internal medicine practice in Chattanooga serving adult patients seeking ongoing management of chronic conditions, preventive care, and complex medical problems. His practice sits within Chattanooga's broader primary care landscape, where access to physicians accepting new patients and offering same-week appointments remains competitive. This profile covers what his practice offers, how it compares to other internal medicine options in the city, and what to expect during an initial visit.
What Dr. Duplooy's Practice Actually Is
An internal medicine physician focuses on the diagnosis and long-term management of diseases affecting multiple organ systems in adults. Unlike family medicine, which treats children and adults, internal medicine centers on adult patients. Dr. Duplooy's practice handles conditions including hypertension, diabetes, heart disease, lung disease, and gastroenterology issues, as well as preventive care such as annual physicals and screening for cancer and cardiovascular risk. The practice operates as a direct appointment-based office rather than a drop-in clinic.
Services and Insurance
Dr. Duplooy accepts Medicare, commercial insurance plans, and some self-pay patients, though specific plans accepted should be verified by calling the office. Internal medicine visits typically include a comprehensive history and physical examination. Initial new-patient visits average 45 minutes to an hour and cost between $150 and $250 out-of-pocket after insurance, depending on your deductible and coinsurance. Established patient follow-ups range from 15 to 30 minutes and cost $75 to $150 out-of-pocket. Many patients' insurance covers annual preventive visits at no cost.
The practice offers on-site basic laboratory services, EKG testing, and vaccinations. More complex testing such as imaging or endoscopy is referred to specialists or imaging centers elsewhere in Chattanooga.
How It Compares to Other Chattanooga Internal Medicine Options
Chattanooga has several large primary care practices affiliated with Erlanger Health System and Ascension Saint Thomas, which typically have longer new-patient waits (2 to 3 weeks) and shorter appointment slots (20 minutes for established patients). Smaller independent practices like Dr. Duplooy's often provide longer initial consultations and same-week or next-week availability for new patients. The trade-off is that independent practices may have fewer specialists on-site and require external referrals for complex imaging or procedures. For patients prioritizing continuity with a single physician and longer visit times, an independent internal medicine practice suits better. For patients wanting extensive on-site specialty care, system-affiliated practices like those within Erlanger may be more efficient.
Who This Practice Suits and Who It Does Not
Dr. Duplooy's practice suits adults with chronic conditions needing ongoing medication management, preventive care, and coordinated specialist referrals. It also suits patients seeking a single long-term primary physician rather than rotating among multiple doctors. The practice is not appropriate for acute care (go to an urgent care or emergency department instead) and does not deliver pediatric care. Patients needing frequent same-day appointments or on-site specialties may find system-based practices more convenient, though this depends on your specific condition.
What the First Visit Involves
Schedule by phone. Arrive 15 minutes early to complete a patient history form and insurance verification. Bring a photo ID, insurance card, and a list of current medications and supplements. The physician will review your medical history, perform a physical examination, and discuss any chronic conditions or preventive needs. Lab work or EKG may be ordered based on your age and health status. The appointment concludes with a treatment or management plan and discussion of follow-up scheduling. Expect to spend 45 minutes to an hour in the office.
Hours, Parking, and Logistics
Office hours are Monday through Friday, 8 a.m. to 5 p.m., with some extended evening slots available on select days; confirm current hours and whether telehealth visits are offered. The practice occupies a standard office building with dedicated patient parking, no paid parking required. The office is wheelchair accessible. Chattanooga traffic is generally light except near downtown during morning and evening rush hours, so plan to arrive 10 to 15 minutes before your appointment time. Public transit options to most medical office locations in Chattanooga are limited; driving is the most reliable option.
Dr. Duplooy's practice offers the continuity of care and appointment flexibility that many Chattanooga patients seek in an internal medicine physician, without the system delays of larger group practices. For adults managing multiple chronic conditions or seeking a consistent long-term medical relationship, this independent practice model fills a real gap in the city's primary care landscape.
