If you or a loved one are scheduled for surgery, you may be wondering how much anesthesia will cost. Luckily, Medicare provides coverage for medically necessary anesthesia services. But how much does Medicare actually pay for each anesthesia unit? This question has been on the minds of many patients and their families.
The answer is not as straightforward as you may think. Medicare uses a complex payment formula that takes into account a variety of factors, including the type of anesthesia used, the physician’s expertise, and the geographic location of the procedure. Depending on these factors, Medicare typically pays between $21 and $29 per anesthesia unit. However, these rates can vary widely and may be subject to adjustment based on various circumstances.
Understanding the costs of anesthesia can be an important factor when considering medical procedures and treatments. By knowing how much Medicare pays for anesthesia units, patients and their families can make informed decisions about their healthcare and financial planning. In this article, we will take a closer look at Medicare payment rates for anesthesia services, including how they are calculated and what patients can expect to pay out of pocket.
Medicare Reimbursement Policies for Anesthesiology Services
Medicare is a federal health insurance program that provides coverage to people aged 65 and older, as well as younger people with certain disabilities and medical conditions. It covers a wide range of medical services, including anesthesiology services. However, the amount that Medicare pays for these services can vary depending on a number of factors.
- Medicare sets payment rates for anesthesiology services based on the Current Procedural Terminology (CPT) codes that are used to describe these services.
- The payment rate for each CPT code is based on the relative value units (RVUs) that are assigned to that code. RVUs take into account the time, skill, and resources required to provide the service.
- In addition to the RVU-based payment rate, Medicare may also adjust payments based on geographic location and other factors.
Overall, Medicare pays per anesthesia unit, with the specific payment rate depending on the RVUs assigned to the specific CPT code for the medical service. It’s important to note that Medicare reimburses only for anesthesia services provided by a qualified anesthesiologist or certified registered nurse anesthetist (CRNA).
Understanding anesthesia units and how they are calculated
As we dive into the topic of how much Medicare pays per anesthesia unit, it’s essential to first understand what anesthesia units are and how they are calculated. Anesthesia units are used to measure the intensity of anesthesia required for a specific medical procedure. The more intense the anesthesia is needed, the higher the number of anesthesia units required.
Anesthesia units are calculated based on three factors, including the patient’s age, the patient’s physical status, and the type of procedure being performed. The American Society of Anesthesiologists (ASA) has developed a system for defining the physical status of patients undergoing surgical procedures. This system ranges from a healthy patient with no underlying medical conditions (ASA 1) to a patient who is almost dying (ASA 5).
- The age of the patient: Younger patients require fewer anesthesia units as they tend to have healthy organ functions and generally require less anesthesia. Meanwhile, elderly patients require more anesthesia units due to the decline in physiological functions that accompany aging.
- The patient’s physical status: A healthy patient requires fewer anesthesia units than a patient with underlying medical conditions. This is because the latter requires more intensive monitoring and treatment to maintain stable physiological functions during the surgical procedure.
- The type of procedure: Different types of surgeries require different levels of anesthesia. For example, a deep abdominal surgery requires more anesthesia units than a superficial skin procedure.
Once the anesthesia units are calculated, the cost of anesthesia is derived by multiplying the number of anesthesia units by a conversion factor. This conversion factor varies between different regions and medical facilities. For instance, an anesthesia unit may be charged at $5 or $10 per unit at different medical centers. It’s essential to note that the cost of anesthesia includes various components, such as the drugs used, the equipment required, and the personnel needed to administer and monitor the anesthesia during the surgery.
Conclusion
Understanding the calculation of anesthesia units is critical to evaluating the cost of anesthesia services for specific medical procedures. It is important to remember that the cost of anesthesia varies depending on multiple factors such as patient age, physical status, and the type of procedure. Overall, the cost of anesthesia is likely to increase with an increase in anesthesia units required for a specific procedure.
Now that you understand anesthesia units and how they are calculated, you can also appreciate the variation in cost for anesthesia services in different medical facilities.

Factors affecting reimbursement rates for anesthesia services
Medicare uses a fee schedule to determine reimbursements for anesthesia services, which are billed in units. One unit of anesthesia represents 15 minutes of service. The payment rate per unit varies based on several factors, including:
- Geographic location – Payment rates can differ based on the state and region of the country in which the service is provided. For example, Medicare payments for anesthesia services in rural areas are generally higher than in urban areas.
- Provider type – Payment rates can differ depending on the type of provider administering the anesthesia. For example, an anesthesia procedure performed by a physician will have a different payment rate than one performed by a nurse anesthetist.
- Procedure complexity – Payment rates can differ based on the complexity of the procedure. More complex procedures may require more anesthesia units and, therefore, may receive a higher payment rate per unit. Medicare uses six base units to represent different levels of anesthesia complexity, ranging from anesthesia for a simple diagnostic procedure to anesthesia for a major surgical procedure requiring prolonged care.
- Time spent administering anesthesia – Payment rates can differ based on the length of time it takes to administer the anesthesia. Providers bill in 15-minute increments, with each increment representing one unit of anesthesia. Medicare offers additional units of anesthesia payment beyond the initial base units for prolonged anesthesia care.
Below is a table that outlines the base unit payment rates for anesthesia services as set by Medicare in 2021. Note that these rates are adjusted based on geographic location, so the actual payment rate per unit may differ depending on where the service is provided.
| Base Units | Payment Rate (National) |
|---|---|
| 0 | $22.92 |
| 1 | $45.05 |
| 2 | $68.83 |
| 3 | $93.69 |
| 4 | $121.23 |
| 5 | $149.33 |
| 6 | $177.44 |
These factors can influence the reimbursement rates for anesthesia services and can impact the overall payment a provider receives for their services. Providers should also be aware of changes to the fee schedule, which can impact their reimbursement rates, and always verify the payment rates with Medicare directly.
Anesthesia modifiers and their impact on Medicare payments
As we mentioned earlier, Medicare pays for anesthesia services based on a unit value, which is determined by the base units, time units, and any applicable anesthesia modifiers. These modifiers can have a significant impact on the overall payment received by anesthesia providers.
- AA modifier: Anesthesia services performed personally by the anesthesiologist or CRNA – this modifier does not affect the payment rate.
- QK modifier: Medical direction of two, three, or four concurrent anesthesia procedures involving qualified individuals – this modifier increases the payment rate by 50% for each additional concurrent procedure.
- QX modifier: CRNA service: with medical direction by a physician – this modifier reduces the payment rate by 50% since the CRNA’s services are being supervised by a physician.
It’s important to note that not all modifiers affect payment rates in the same way, and some modifiers may not affect payments at all. For example, the AA modifier only indicates that the service was personally performed by the anesthesiologist or CRNA, and does not impact payment rates.
To get a clearer picture of how anesthesia modifiers impact Medicare payments, let’s take a look at a sample payment calculation:
| Service | Base Units | Time Units | Anesthesia Modifier | Total Units | Payment Rate | Total Payment |
|---|---|---|---|---|---|---|
| Anesthesia for knee surgery | 5 | 100 | AA | 5 | $22.87 | $114.35 |
| Medical direction of two anesthesia procedures | – | – | QK | 2 | $11.44 | $22.88 |
| CRNA service with medical direction by a physician | 2 | 30 | QX | 1 | $5.72 | $5.72 |
| TOTAL | – | – | – | 8 | – | $142.95 |
In this example, the QK modifier increased the payment by 50% for medical direction of two anesthesia procedures, while the QX modifier decreased the payment by 50% for the CRNA service. Overall, the modifiers resulted in a total payment of $142.95 for the anesthesia services provided.
Billing and coding procedures for Medicare anesthesia reimbursement
Medicare reimbursement for anesthesia services is based on the number of units provided. Each anesthesia unit is assigned a value, known as the conversion factor, which is determined annually by Medicare. The conversion factor is based on several factors, including the cost of living and the cost of providing anesthesia services in a particular geographic area.
To bill for anesthesia services provided to Medicare beneficiaries, healthcare providers must use Current Procedural Terminology (CPT) codes. Anesthesia codes are divided into two main categories: base units and time units. Base units are assigned to specific procedures and reflect the relative difficulty or complexity of the service provided. Time units are based on the length of the procedure and are calculated based on a specific formula.
Billing and coding procedures for Medicare anesthesia reimbursement: Anesthesia billing codes
- Anesthesia code range is 00100 – 01999
- Major categories for anesthesia codes are: physical status modifiers, anesthesia service modifiers, and anesthesia time reporting modifiers
- Physical status modifiers: P1 – P6, used to indicate the patient’s status and overall health
- Anesthesia service modifiers: AA, AD, G8, G9, QX, and QZ, used to identify the type of service provided or whether the anesthesia was personally performed by the provider
- Anesthesia time reporting modifiers: GC, GD, and GZ, used to indicate the start and end times for the anesthesia service
Billing and coding procedures for Medicare anesthesia reimbursement: Calculating anesthesia units
Medicare uses a specific formula to calculate the number of anesthesia units for a given procedure. The formula takes into account the base units assigned to the procedure and the amount of time the procedure takes to complete. The formula is as follows:
| Total units = (Base units + Time units) x Conversion factor |
The time units are calculated as follows:
| 15 minute increment ≤ time ≤ 30 minute increment | 1 unit |
| More than a 30-minute increment | Additional time units based on the total time rounded up to the nearest 15-minute increment |
It is important for healthcare providers to accurately report the base units and time units for anesthesia services to ensure proper reimbursement. Failure to report services accurately can result in claim denials and loss of revenue for healthcare providers.
Payment rates for anesthesia services furnished by CRNAs
For those who may be unfamiliar, CRNA stands for Certified Registered Nurse Anesthetist. These professionals are trained to administer anesthesia, monitor the patient during the procedure, and ensure the patient’s safe recovery from anesthesia following the procedure.
When it comes to payment rates for anesthesia services furnished by CRNAs, Medicare pays for these services based on the level of supervision required by the CRNA during the procedure. There are three levels of supervision:
- General Supervision: CRNA services are furnished under the overall direction of a physician who is immediately available if needed.
- Medical Direction: CRNA services are furnished under the medical direction of a physician who is physically present during the most critical or key portion of the anesthesia, and immediately available if needed.
- Medical Direction with Indirect Supervision: CRNA services are furnished under the medical direction of a physician who is not physically present during the most critical or key portion of the anesthesia but is immediately available if needed. The physician must be available to be contacted by the CRNA during the procedure.
The payment rates for anesthesia services furnished by CRNAs vary based on the level of supervision required. Here is a breakdown of the Medicare payment rates for 2021:
| Level of Supervision | Payment Rate (per anesthesia unit) |
|---|---|
| General Supervision | $21.39 |
| Medical Direction | $25.08 |
| Medical Direction with Indirect Supervision | $17.51 |
It is important to note that these payment rates are specific to Medicare and may vary based on the individual insurance plan or facility. Additionally, some states may have different payment rates or regulations for CRNAs. It is always best to check with the specific insurance company or facility to confirm payment rates for anesthesia services furnished by CRNAs.
Anesthesia fee schedule updates and changes.
Medicare pays for anesthesia services based on the anesthesia fee schedule. This fee schedule is updated annually by the Centers for Medicare and Medicaid Services (CMS) to ensure that payments are fair and reasonable for both the provider and the patient.
Here are some key updates and changes to the anesthesia fee schedule:
- Conversion Factor: The conversion factor is the multiplier used to calculate the payment for each anesthesia unit. In 2021, the conversion factor is $22.13, which is an increase from the 2020 conversion factor of $22.20.
- Time Units: The anesthesia fee schedule includes specific time units that are used to calculate payment for anesthesia services. In 2021, the time units for base anesthesia services range from 0 to 60 minutes, with each time unit valued at $16.63.
- Geographic Adjustments: CMS may adjust payment for anesthesia services based on the geographic location of the provider. The anesthesia fee schedule includes a list of geographic practice cost indices (GPCIs) that reflect the differences in costs for practice expenses across different regions of the country.
Anesthesia Payment Reform
The anesthesia fee schedule is just one aspect of Medicare’s payment policies for anesthesia services. In recent years, CMS has implemented several payment reforms aimed at improving the value and quality of anesthesia care. These reforms include:
- Value-Based Payments: CMS has implemented several value-based payment models for anesthesia services, including the Anesthesia Conversion Factor (ACF) model and the Anesthesia Quality Payment Program (AQPP).
- Bundled Payments: Under the Bundled Payments for Care Improvement (BPCI) initiative, CMS provides bundled payments for certain episodes of care that include anesthesia services.
- Alternative Payment Models: CMS has also explored alternative payment models for anesthesia services, such as accountable care organizations (ACOs) and medical homes.
