Total Annual Prescription Volume Survey

Myers and Stauffer is the vendor contracted to conduct the annual TAPV survey of pharmacy providers. The prescription volume data collected from pharmacies will be used to determine their dispensing fee tier for the following calendar year. Each year, surveys will be distributed starting October 1st and will be due by October 31st. Providers who fail to participate in the survey will be placed in the lowest dispensing fee tier of $9.31. Below are the current dispensing fee tiers:

Total Annual Prescription Volume Dispensing Fee
0 – 59,999 TAPV $13.40
60,000 – 89,999 TAPV $11.49
90,000 – 109,000 TAPV $10.25
110,000+ TAPV $9.31
Rural Pharmacy $14.14
Government Pharmacy $0.00

Pharmacies which meet the regulatory definition of a government or rural pharmacy will have their dispensing fee determined by their pharmacy type and will not be included in the TAPV surveying process as defined in 10 CCR 2505-10, Sections 8.800.1 and 8.800.13.

Providers should fill out the survey form for all pharmacy NPIs within their organization that are enrolled with Colorado Medicaid.

Frequently Asked Questions

Why might Colorado Medicaid request information about my pharmacy’s drug purchases?

In order to maintain an AAC program with reimbursement that reflects current pharmaceutical market conditions, the AAC rate schedule is based on the actual acquisition costs of Medicaid pharmacy providers. The calculated rates are designed to reimburse ingredient costs at a rate that is reflective of the average costs that Colorado pharmacy providers are experiencing.

Why should I send information about my pharmacy’s drug purchases to Colorado Medicaid, if requested to do so?

The AAC rate schedule is based on Medicaid pharmacy providers’ actual experiences purchasing selected drug products. Providers who receive requests for drug purchase information are strongly encouraged by the State to provide the requested information to insure that the established AAC rates fully consider providers’ cost experience in the marketplace.

What are the acceptable methods to transmit my drug purchase information?

For drug purchases made during the identified time period requested by CO DHCPF, providers can simply retrieve the invoices reflecting their purchases, photocopy the records, then mail the copies to Myers and Stauffer. A provider can also provide this data via email in an electronic format. Electronic files can be accepted in Excel, PDF, and text file format. A provider may request that its wholesaler electronically send this information to Myers and Stauffer. Informational letters that accompany the survey request will have more detailed submission information.

What will Colorado Medicaid do with drug purchase information it receives from me?

CO DHCPF will use drug purchase information submitted by pharmacies for the purpose of establishing, evaluating, maintaining, and updating AAC rates. CO DHCPF has contracted with the firm of Myers and Stauffer to assist in developing and maintaining the AAC program. Pharmacies are encouraged to submit copies of purchase information, rather than originals as information submitted will not be returned.

Why might my pharmacy be selected to provide drug purchase information?

All pharmacy providers enrolled in the Colorado Medicaid program are eligible for random selection to provide drug purchase information.

How often might I be asked to provide drug purchase information?

All pharmacy providers enrolled in the Colorado Medicaid program are eligible for selection to provide drug purchase information. A random sample of pharmacies are selected to participate in acquisition cost studies on a monthly basis. We anticipate a frequency of no more than once per year.

For what time period would my drug purchase information be requested?

All pharmacy providers enrolled in the Colorado Medicaid program are eligible for selection to provide drug purchase information. When a request is received for drug purchase information, the time frame of the data requested will be for the most recent 30 day period. If that drug purchase information for the most recent 30 day period is not readily available, then the next most recent 30 day period will be acceptable.

How will the AAC rates be updated? How do I report concerns about product prices or product availability?

Baseline AAC rates will be calculated monthly based on invoice costs submitted by Colorado Medicaid pharmacies. To respond to changes in the marketplace, AAC rates will also be reviewed weekly for published pricing changes and daily when inquiries are received through the pharmacy help desk. When contacting the pharmacy help desk, you will be asked to provide information regarding your request. Information should include, but not be limited to drug purchase summaries, invoices, remittance advices, and other such documentation. In the absence of sufficient information to assess concerns about AAC rates or other aspects of the AAC program, provider requests cannot be fully considered. Providers initiating requests for review of AAC rates or other issues may be contacted to request supporting documentation or other information.

What if my cost is higher than the AAC reimbursement rate?

AACs are based on the average acquisition cost of pharmacy providers and therefore may sometimes be below the costs experienced by individual providers. Adjustments will be made to the AAC rate when the overall average has increased. If your acquisition costs have increased, you may contact Myers and Stauffer’s Colorado pharmacy help desk at 800.591.1183 to report your concerns and request a rate review. AAC rates will be adjusted when the overall average cost of a drug has increased. AAC rates will not be eligible for adjustment due to an individual provider’s inability to purchase the drug below the AAC if the overall average has not changed.

How often will the AAC rate schedule on the Myers and Stauffer Colorado pharmacy website be updated?

The AAC rate listing will be updated weekly.

I didn‘t respond to the claims volume survey, so Medicaid doesn’t have my claims volume. What’s my dispensing fee?

Providers who didn’t respond to the Colorado Medicaid Claims Volume survey will default to the lowest dispensing fee tier.

Can my dispensing rate be adjusted if my claims volume changes?

Colorado Medicaid will request claims volume numbers from providers annually. Dispensing fees set at those numbers will remain until the next year’s survey of claim’s volume.
