Dan W. Drinnon, MD in Chattanooga: An Internal Medicine Practice with Family-Centered Care

Dan W. Drinnon, MD, operates a general internal medicine practice in Chattanooga that accepts multiple insurance plans and serves adult patients seeking ongoing primary care and chronic disease management. His practice sits within Chattanooga's landscape of independent internists and primary care providers, many of whom operate through larger health systems rather than as solo or small-group practitioners.

What Dan W. Drinnon, MD actually does

Drinnon practices general internal medicine, meaning he manages conditions common in adults: hypertension, diabetes, high cholesterol, heart disease prevention, thyroid disorders, and general acute illness. Unlike specialized cardiologists or endocrinologists, an internist handles the full range of non-surgical adult health problems and often coordinates referrals to specialists when needed. Drinnon's practice operates independently, a structure that differs from physicians employed by Erlanger Health System or Chattanooga-based primary care clinics affiliated with multi-specialty hospital networks.

Services and what to expect

Drinnon's office provides routine physical exams, chronic disease follow-up visits, medication management, preventive screening (including cholesterol panels and diabetes screening), and minor acute care for established patients. New-patient appointments typically involve a full medical history, physical exam, and baseline laboratory work; expect this visit to run 30 to 45 minutes. Established-patient visits for follow-up or acute care are shorter, usually 15 to 25 minutes.

Pricing for office visits varies by insurance plan. Patients with commercial insurance pay a copay (typically $20 to $50) plus any coinsurance; uninsured patients should request a cash-pay rate at the time of scheduling. The practice accepts Medicare and most major Chattanooga-area commercial plans; confirm coverage when calling to schedule.

How Drinnon compares to other Chattanooga internists

Most general internists in Chattanooga work within Erlanger, Parkridge, or Pentridge/United Health Centers, where they share call schedules and refer to in-house specialists. Drinnon's independent model offers continuity: if he manages your diabetes, he sees you consistently rather than rotating with other physicians. The tradeoff is that after-hours care may direct you to an urgent care or ER rather than to Drinnon himself; ask during your first visit how evening and weekend concerns are handled. For patients who prefer a large medical center with 24-hour specialist availability on-site, a health-system-based internist may suit you better. For those who value a single long-term relationship with a physician who knows their full history, an independent practice often delivers that more reliably.

Who this practice serves well and who it doesn't

Drinnon's practice is ideal for established residents with stable or moderately complex chronic conditions who plan to stay in Chattanooga long-term and want one doctor managing their overall health. It also suits adults without significant mental health or substance-use concerns who can manage scheduled office appointments during business hours. It is less suitable for patients experiencing psychiatric crisis, active addiction, or homelessness, since an independent internal medicine office lacks social work and behavioral health resources on-site. It is not a walk-in urgent care; acute minor illness (strep throat, urinary tract infection) is handled as an established patient with same-day or next-day appointment availability when possible, but walk-ins are not accommodated.

What your first visit involves

Call ahead to confirm that Drinnon is accepting new patients; many primary care practices in Chattanooga have temporary closures to new patients during high-volume periods. New-patient appointments require arrival 10 to 15 minutes early for registration and insurance verification. Bring your insurance card, a list of current medications (including over-the-counter and supplements), and any recent medical records from a previous doctor. Drinnon will review your medical history, perform a complete physical, and may order baseline labs (blood work, urinalysis) if your records are unavailable. The visit is typically unhurried and sets the foundation for ongoing care; use it to discuss your main health concerns and any preventive screening you need.

Hours, location, and logistics

Most independent physician offices in Chattanooga operate Monday through Friday, 8 a.m. to 5 p.m., with limited or no Saturday hours; call to confirm Drinnon's specific schedule, as hours may vary seasonally. Parking is typically on-site or in a shared medical office lot. If you require evening or weekend urgent care, Chattanooga has several walk-in urgent care centers including Urgent Care Express and US HealthWorks, though these do not replace an established primary care relationship.

An independent internist who builds a sustained patient relationship offers consistency that shifts the burden of remembering your history away from you. Drinnon's practice reflects that model within Chattanooga's primary care landscape.
