Davis Karrie L. FNP in Chattanooga: Cardiac Nursing in Primary Care

Karrie L. Davis is a family nurse practitioner (FNP) in Chattanooga who provides primary and preventive cardiology services, blending routine cardiovascular risk management with hands-on patient education in a private practice setting that operates outside the hospital system model many cardiologists in the region use.

What Davis Karrie L. FNP actually is

An FNP is not a physician but a graduate-trained nurse with prescriptive authority, clinical training in diagnosis and treatment, and the legal right to see patients independently in Tennessee. Davis works in cardiovascular health within a primary-care framework rather than as a cardiologist (MD or DO with cardiology fellowship), which means her scope includes managing hypertension, high cholesterol, atrial fibrillation, and post-cardiac-event follow-up without the catheterization lab or inpatient hospital work that defines a full cardiology practice. For Chattanooga patients seeking continuity cardiovascular care without scheduling delays common at hospital-based cardiology departments, this distinction matters in access and convenience.

Services and what to expect for cost and visit structure

Davis provides office-based cardiovascular evaluation, medication management, and lifestyle coaching. Common services include blood pressure monitoring, EKG interpretation, lipid screening and statin therapy initiation, management of arrhythmias (particularly afib), and coordination with cardiologists for patients requiring interventional procedures or advanced imaging. FNPs in Tennessee can write prescriptions, order imaging and labs, and refer to specialists.

Pricing follows standard private-practice office visit model: established-patient visits typically run 20 to 30 minutes; new patients should budget 45 to 60 minutes and often pay $150 to $300 out of pocket depending on your insurance plan's copay or deductible. Many insurances cover FNP visits at the same rate as physician visits when ordered in a primary-care context; verify with your plan whether cardiology specialty copays apply or primary-care rates do. Some practices bundle preventive cardiovascular screenings (lipid panels, EKG, blood pressure assessment) into an initial appointment.

Comparison to Chattanooga cardiologists and cardiology practices

Chattanooga has hospital-affiliated cardiology practices through Erlanger Health System and CHI Memorial, where board-certified cardiologists (MD/DO with cardiology fellowship) handle complex cases, invasive diagnostics, and percutaneous interventions. These groups excel for patients post-heart attack, with complex arrhythmias requiring electrophysiology, or those needing imaging such as stress tests and cardiac catheterization.

Davis's FNP practice suits patients whose cardiovascular needs lean toward prevention, stable chronic disease management, and medication refills. If your insurance offers office visit copays of $20 to $40 (versus $50 to $75 specialty copays), and your condition is blood pressure control, cholesterol management, or atrial fibrillation stable on medication, the FNP route avoids both wait times (hospital cardiology often runs 6 to 8 weeks for new patients) and specialty-level cost sharing. If you require a stress test, catheterization, or your condition is newly diagnosed and unstable, a hospital cardiologist is the standard first step.

Who this suits and who it does not

Choose Davis for ongoing management if you have controlled hypertension or high cholesterol, take cardiac medications regularly, need routine monitoring, or want a primary-care provider with specific cardiovascular expertise who you can see regularly without referral delays. Patients who value provider continuity over a large team structure often find FNP practices more accessible.

Do not choose this for acute chest pain (go to an ER), newly diagnosed complex arrhythmias, or when you need interventional cardiology, advanced imaging, or specialist-level diagnostics. If your cardiologist has already referred you elsewhere for procedures, follow that referral.

What the first visit involves

A new-patient appointment typically begins with a comprehensive history including family cardiac history, smoking status, physical activity, diet, and current medications. Expect vital signs (blood pressure on both arms, heart rate, rhythm check), auscultation (stethoscope exam of heart and lungs), an EKG if not recently done, and basic labs such as lipid panel and glucose screening if you have not had recent bloodwork. The provider will discuss findings, explain any medications recommended, and outline a prevention or management plan. Bring insurance cards and a list of all current medications, including over-the-counter supplements.

Hours, location, and logistics

Verify current hours and location directly with the practice, as FNP office schedules often run Monday through Friday, 8 a.m. to 5 p.m., with or without lunch closure. Most private practices offer parking directly adjacent to or on-site. Request appointment availability when calling; some practices hold same-week or next-week slots for established patients with urgent medication questions or blood pressure concerns.

Karrie L. Davis brings cardiovascular nursing expertise to Chattanooga's primary-care market for patients who need ongoing prevention and medication management without hospital wait times or specialty-level cost sharing.
