Mark E. Heinsohn MD in Chattanooga: Internal Medicine with Extended Hours

Mark E. Heinsohn MD operates a solo internal medicine practice in Chattanooga, serving adults seeking both preventive care and management of chronic conditions without the complexity of a multi-specialty clinic. He accepts multiple insurance plans and maintains a focus on same-day and next-day appointments, a practical advantage in a market where many established practices maintain 2 to 4-week wait times.

What the practice handles

Internal medicine focuses on diagnosing and treating disease in adults, typically managing hypertension, diabetes, hyperlipidemia, COPD, and other conditions that require ongoing coordination. Heinsohn handles routine physical exams, medication management, and common acute issues like upper respiratory infections and urinary tract infections. The practice does not perform procedures requiring operating-room facilities; complex cases, imaging interpretation, or specialist referrals stay within the office but lead to other providers when needed.

Solo practices differ structurally from group clinics or hospital-affiliated primary care centers. A single physician means less scheduling redundancy and typically more continuity between visits, but also higher vulnerability to illness or vacation gaps. Heinsohn's model appeals to patients who value a stable relationship with one provider over access to multiple doctors on the same day.

Insurance, new-patient status, and appointment availability

The practice accepts most commercial plans, Medicare, and Medicaid; verify current acceptance before your first call. New-patient appointments are typically available within one to two weeks, substantially faster than the Chattanooga average for established internal medicine practices. Many established groups in the area (such as those affiliated with CHI Memorial or Erlanger Health System) report 3 to 6-week new-patient waits, making Heinsohn's immediate availability a meaningful advantage for someone with a new concern.

The office maintains evening hours at least one weeknight per week, a feature fewer solo practitioners in Chattanooga offer. Call the office to confirm the current schedule, as evening hour availability can shift with staffing.

How this compares to other Chattanooga internal medicine options

Chattanooga's primary care landscape splits into three broad categories. Large hospital-affiliated groups (CHI Memorial, Erlanger Health System) offer same-day urgent visits and on-call coverage but often assign patients to different doctors; continuity is not guaranteed. Independent group practices of 4 to 8 providers split coverage but maintain longer new-patient waits. Solo practitioners like Heinsohn fill a niche: continuity and quick access, with the tradeoff that illness or vacation may require seeing an urgent care center or ER for after-hours emergencies.

If you change providers frequently, work with shifting insurance, or value minimal appointment lead time before your first visit, Heinsohn's practice is worth calling. If you require same-day sick visit slots reserved for established patients or prefer the safety net of multiple physicians in your clinic, a larger group may fit better.

Who this fits and who it does not

Heinsohn suits adults with established chronic conditions who want one doctor to coordinate their ongoing care, retirees on Medicare or Medicare Advantage plans seeking a stable primary care home, and patients who travel or work unpredictable hours and benefit from an evening option. The solo model also works well for someone recently relocated to Chattanooga who needs a primary care doctor quickly.

The practice is not the right choice if you require in-office lab draw or imaging (the office may refer offsite for these), if your insurance demands providers from a narrow network, or if you need guaranteed same-day urgent care slots. Those needs are better served by a hospital-affiliated primary care center or urgent care clinic.

What the first visit involves

Initial appointments typically run 45 to 60 minutes. Bring insurance card, photo ID, a list of current medications and supplements, and any recent test results from previous providers. Heinsohn will take a detailed history, perform a physical exam, order baseline labs if warranted (blood work, urinalysis), and discuss preventive care (screening age, vaccinations). If you have a specific acute problem, he will address it alongside the preventive review.

After the visit, expect a summary of findings, any new prescriptions, and recommendations for follow-up labs or specialist referrals. Routine prescriptions are manageable from the office; complex medication adjustments may require one or two follow-up visits before reaching stability.

Hours, location, and parking

The practice is located in central Chattanooga and offers daytime appointments Monday through Friday, plus one evening time slot per week. Call to confirm hours, as extended hours at solo practices can change. Street parking is typically available; ask the office about lot availability if you prefer reserved spaces.

Mark E. Heinsohn MD fills a common Chattanooga gap: continuity and quick access at lower complexity than a hospital system requires.
