Once your insurance carrier has processed your anesthesia claim—typically within 30 to 45 days after your procedure—you will receive an account statement from Capital Anesthesia Partners. This statement will outline the services provided, payments received from your insurer, and any remaining patient responsibility, including co-payments, co-insurance, and/or deductible amounts.
You may also obtain your insurer’s summary of benefits, known as an Explanation of Benefits (EOB), directly from your insurance provider.
We offer several secure and convenient ways to pay your bill:

Capital Anesthesia Partners participates with nearly all insurance carriers accepted at the facilities where we provide care. As an in-network provider, we have negotiated rates with your insurance company for our services. Your individual financial responsibility—such as co-payments, co-insurance, or deductibles—is determined by your specific plan and benefits.
It is common for patients to receive multiple bills for a single outpatient procedure. These may include:
Some insurance plans include “medical necessity” policies that may limit coverage for anesthesia services during endoscopic procedures. While we will submit claims to your insurance carrier, coverage decisions are made by your insurer based on your individual policy. As such, coverage is not guaranteed, even when we are in-network.
We believe in helping patients better anticipate the cost of care. On average:
Patients with high-deductible health plans who have not yet met their annual deductible may incur higher out-of-pocket expenses, which can exceed $500.
Health insurance and medical billing can be complex. For questions about your coverage, benefits, or plan requirements—including co-pays, co-insurance, deductibles, or medical necessity policies—please contact your insurance provider or your employer's Human Resources department.
For questions about your anesthesia bill or account balance, please contact our billing office at 1-800-222-1442.

For patients without active health insurance—or those who choose not to use their coverage—Capital Anesthesia Partners offers a discounted self-pay rate when payment is made in advance of the procedure.
The self-pay fee for anesthesia services is $500 per encounter. This flat rate applies regardless of whether you undergo a single procedure (such as a colonoscopy or upper endoscopy/EGD) or a combined (“double”) procedure performed during the same visit.
To arrange prepayment, please contact our office at 202-780-1700 prior to your procedure. Payment is accepted by credit or debit card.

Knowing the difference between a screening and diagnostic colonoscopy can help you better understand your insurance coverage and potential out-of-pocket costs.
A screening colonoscopy is a preventive procedure performed on patients without symptoms to detect colorectal cancer or precancerous polyps. Under the Affordable Care Act (ACA), most private insurers are required to cover recommended preventive services—like screening colonoscopies—at no cost to the patient, meaning no co-pays or deductibles in many cases.
A diagnostic colonoscopy is performed to evaluate symptoms or specific clinical concerns, such as:
Because this type of procedure is not considered preventive, deductibles, co-insurance, or co-pays may apply based on your insurance plan.
Insurance coverage is determined not only by how the procedure is scheduled, but also by clinical findings and your medical history.
Historically, a gap in federal law meant that patients could incur costs if a screening colonoscopy led to additional findings (such as polyp removal). This created a financial barrier to preventive care.
In 2020, Congress passed The Removing Barriers to Colorectal Cancer Screening Act of 2020, which is gradually reducing patient cost-sharing for these scenarios. This change is being phased in over time, with the goal of eliminating out-of-pocket costs for follow-on care associated with screening colonoscopies by 2030.
Insurance policies vary, and coverage decisions ultimately rest with your insurer. For the most accurate information about your benefits—including how your procedure will be classified and what costs may apply—please contact your insurance provider or your employer’s benefits department. You can also view a flowchart prepared by the AGA Institute for additional information.
If you have questions about anesthesia services or billing, our team is here to help.
Anesthesia services provided during an esophagogastroduodenoscopy (EGD) are not considered preventive under the Affordable Care Act (ACA). As a result, these services are typically not covered at 100%, and patients may have financial responsibility based on their individual insurance plan.
Depending on your benefits, this may include:
Anesthesia billing is based on a standardized formula that combines:
If you would like an estimate of your anesthesia costs prior to your procedure, please contact our corporate office. Our team will be happy to assist you in understanding your expected financial responsibility.

When a colonoscopy is performed alongside another procedure—such as an upper endoscopy (EGD)—the Affordable Care Act (ACA) screening benefit typically does not apply to anesthesia services. As a result, patients may have out-of-pocket costs based on their insurance plan, including:
Anesthesia services are billed using a standardized methodology that combines:
Unlike procedural billing, anesthesia is not billed separately for multiple procedures performed during the same session.
Although anesthesia for a standalone screening colonoscopy is often covered in full, combining procedures may change how anesthesia services are classified and reimbursed.
That said, having both procedures performed during a single visit is typically more cost-effective overall than scheduling them on separate days. Separate procedures may result in:
By combining procedures, patients can often reduce total costs while minimizing the need for multiple appointments.

A list of the most frequently asked questions is available below.
Monitored Anesthesia Care (MAC) is a specific anesthesia service used to support diagnostic and therapeutic endoscopic procedures. You will be fully sedated but unlike general anesthesia; you will be able to breathe without assistance. During the procedure, a board-certified anesthesiologist or certified registered nurse anesthetist (CRNA) is responsible for conducting a health assessment of the patient to determine the appropriate type of drug to be used, administering the sedative and monitoring vital functions. This careful monitoring process allows our patients to have a better experience with anesthesia to make their procedure as comfortable as possible.
You will meet the anesthesia provider before you go into your procedure. If you have concerns/questions you may address them with him at that time.
The collaboration between anesthesia provers, gastroenterologists, and other members of our care teams have proven to provide a high quality and safe environment for procedures with exceptional patient satisfaction. As a result, MAC has become the standard of care for endoscopy procedures across the nation. The most common endoscopic procedures with MAC services include: Colonoscopy, Upper Endscopy (EGD) and Flexible Sigmoidoscopy.
The sedation used during your procedure is administered by a board-certified Anesthesiologist or Certified Registered Nurse Anesthetist (CRNA). The type of sedation used will be best suited to keeping you comfortable and safe, and mutually agreed upon between the anesthesia provider and the endoscopist. Propofol is the sedation medication most commonly used in our procedures. The sedative is given as an injection through a needle which has already been placed into a vein (an IV). You will relax and fall asleep very quickly (within seconds) after the injection. Your breathing, blood pressure, oxygen levels and other vital signs will be watched closely. Finally, you will wake feeling alert and not worn out or groggy.
Capital Anesthesia Partners strives to be consistent and compliant with the federal coding regulations set forth by the Centers for Medicare and Medicaid Services (CMS). We are not able to change coded charges to manipulate payment methodologies set forth by insurance companies..
Please refer any questions related to medications or supplement to your gastroenterologist.
Glucagon-Like Peptide-1 (GLP-1) Receptor Agonists
All patients talking GLP-1 Receptor Agonists are required to stop these medications at least 7 full days prior to receiving anesthesia services at CAP affiliated sites. E.g. If a procedure is scheduled on a Monday, the medication should be last taken on the previous Sunday, as this would allow seven full days (Mon, Tue, Wed, The, Fri, Sat, and Sun) off the medication, not including the day of the procedure.
Patients that do not hold these medications will have their procedure cancelled.
Common examples of GLP-1 medications include, but are not limited to:
SGL2 Inhibitor Medications
All patients talking SGL2 Inhibitors are required to stop these medications three full days immediately prior to day of procedure. E.g. If a procedure is scheduled on a Monday, the medication should be last taken on the Thursday before, as this would allow three full days (Fri, Sat and Sun) off the medication, not including the day of the procedure.
Patients that do not hold these medications will not receive anesthesia. This policy does allow cases to proceed without anesthesia by GI physician/ASC decision, but anesthesia will not sedate and will not be present to record vital signs.
Other medications and supplements
Please consult with your gastroenterology.
Occasionally patients would like to know which CPT codes we bill for our anesthesia professional fees. A list is provided below for your convenience:
Anesthesia for screening colonoscopy when the post-procedure diagnosis is "normal colon" and no polyps are identified.
Anesthesia for screening colonoscopy but when polyps are identified (and almost always removed) during the procedure. Please note that CPT code 00811-P is used for Medicare patients only.
Anesthesia for lower intestinal endoscopic procedures, endoscope introduced distal to duodenum; not otherwise specified. This CPT code is used when either there is a personal history of polyps in a prior screening or diagnostic colonoscopy or when there are exploratory diagnoses (such as rectal bleeding) that necessitate a colonoscopy.
This CPT code is used when anesthesia is provided for an Esophagogastroduodenoscopy procedure only (i.e. when an EGD is performed and a colonoscopy is not).
Anesthesia for combined upper and lower gi endoscopic procedures, endoscope introduced both proximal to and distal to the duodenum. This CPT code is used when an Esophagogastroduodenoscopy (EGD) and Colonoscopy (either screening or diagnostic/therapeutic) is performed at the same time. Please note that the ACA's screening colonoscopy benefit for anesthesia services does not apply to "double procedures."
Please note that these the CPT codes listed are for anesthesia professional fee reimbursement and will vary from CPT codes billed by your proceduralist (gastroenterologist). We are unable to modify CPT or diagnosis codes on our claims.
