You can get pre-operative clearance from your primary care doctor, a hospital-based pre-operative evaluation clinic, or in some cases an urgent care center that offers the service. Your surgeon’s office will typically tell you which option they prefer, and some hospitals require that clearance be done at their own facility.
Your Primary Care Doctor
For most patients, a primary care doctor is the simplest and most common choice. Your PCP already knows your medical history, current medications, and any chronic conditions, which makes the evaluation faster and more thorough. The visit involves a physical exam, a review of your medications, and an assessment of whether your health is stable enough for anesthesia and surgery. Your doctor will then complete the clearance paperwork your surgeon requires.
If you don’t have a primary care doctor or can’t get an appointment in time, ask your surgeon’s office what alternatives they accept. Some practices are flexible; others are not.
Hospital Pre-Operative Evaluation Clinics
Many hospitals run dedicated pre-operative assessment clinics, sometimes called pre-admission testing centers. Mount Sinai, for example, operates a PreOperative Evaluation and Management (POEM) Center specifically for this purpose. These clinics are staffed by anesthesiologists, nurse practitioners, or physician assistants trained in surgical risk assessment. They interview and examine you, review your medical and surgical history, evaluate your current medications, and order any lab work or tests needed before your procedure.
Your surgeon may refer you directly to one of these clinics, especially if your surgery is being performed at that hospital. The visit is typically scheduled one to three weeks before your procedure, though timing varies. Some clinics see patients as early as three months out, while others operate within a narrower window. A major advantage of hospital-based clinics is that your clearance results go straight into the hospital’s system, reducing paperwork delays on the day of surgery.
Urgent Care Centers
Some urgent care facilities advertise pre-operative clearance as a walk-in service. This can work if you’re generally healthy and need clearance for a low-risk procedure. However, not all surgeons or hospitals accept clearance from urgent care providers. Before booking, confirm with your surgeon’s office that they’ll honor the paperwork. Urgent care doctors also won’t have your long-term medical records, so bring a list of your medications, allergies, past surgeries, and any relevant diagnoses.
When You Need a Specialist
Certain health conditions require clearance from a specialist in addition to your general clearance. If you have advanced heart failure, a history of congenital heart disease, or significant cardiac risk factors, your surgeon may require a cardiology evaluation before proceeding. The 2024 guidelines from the American Heart Association recommend postponing elective surgery and getting a cardiology consultation for patients with unstable or decompensated heart failure.
Pulmonary clearance may be needed if you have severe lung disease, and patients with poorly controlled diabetes or kidney disease may need sign-off from the relevant specialist. Your surgeon or primary care doctor will tell you if any specialist clearances are required. These visits are separate appointments, so factor in the extra time.
What Happens During the Visit
A pre-op clearance is more than a quick physical. The provider reviews your complete medical history, asks about prior reactions to anesthesia, checks your vital signs, and examines your heart and lungs. Depending on your age and health, they may order blood work, an electrocardiogram (EKG), or a chest X-ray. Older patients are significantly more likely to need these tests. Research shows patients aged 66 to 75 are roughly 18 times more likely to receive a preoperative EKG than patients aged 18 to 25, and about three times more likely to get a chest X-ray.
The provider also reviews every medication you take, including supplements, because some need to be stopped before surgery. Blood thinners, certain diabetes medications, and even common supplements like fish oil can affect bleeding or anesthesia. You’ll get specific instructions on what to stop and when.
Telehealth Options
Virtual pre-op visits are increasingly available, particularly for the history-taking and risk assessment portions of clearance. A feasibility study on hybrid telemedicine protocols found that 88% of patients were satisfied with video consultations and preferred them over fully in-person visits. However, certain physical exam components, like assessing your airway for anesthesia safety, are harder to evaluate through a screen. Most programs using telehealth still require at least a partial in-person exam, making them a hybrid rather than a fully remote option. Check with your surgeon’s office to see if a virtual visit is accepted for your specific procedure.
Timing and Validity
Pre-op clearance doesn’t last indefinitely. Federal regulations require that a hospital-based history and physical be completed no more than 30 days before your procedure. If it was done more than 24 hours before surgery, an updated exam documenting any changes in your condition must be completed before you go to the operating room. The anesthesia evaluation specifically should be conducted within 48 hours of your surgery date, though it can initially be performed up to 30 days in advance and then updated closer to the procedure.
In practical terms, most surgeons schedule clearance visits two to four weeks before the operation. If your surgery gets postponed beyond the 30-day window, you’ll need to repeat the process.
Insurance and Cost
Pre-operative clearance visits are billed as standard office visits or consultations, not as preventive care. Your regular copay or deductible applies. The visit is coded with a specific diagnosis indicating it’s a pre-procedural exam rather than a routine checkup, which matters for how your insurer processes the claim. If lab work, an EKG, or imaging is ordered during the visit, those are billed separately and also fall under your medical benefits rather than preventive coverage.
If cost is a concern, ask your surgeon’s office whether their hospital-based clinic bundles pre-op testing into the surgical facility fee. Some do, which can simplify billing. Otherwise, expect the clearance visit and any tests to generate their own claims.
