As of June 2023, the Colorado All Payer Claims Database (CO APCD) contained over one billion claims spanning 2013 through 2022. These claims were submitted by commercial health insurance plans, including Medicare Advantage, voluntarily submitted Employee Retirement Income Security Act (ERISA) and mandated non-ERISA self-insured employer plans, Medicaid, and Medicare Fee-for-Service (FFS). The CO APCD does not contain claims for people covered by Federal health insurance programs such as the Veterans Administration, TRICARE federal employees, or Indian Health Services, and does not include information for uninsured Coloradans.

Analysis of 2022 claims shows that the CO APCD holds information for approximately 70% of insured individuals in Colorado with medical coverage, reflecting over 5 million lives in total across coverage types (medical, dental and pharmacy). Forty commercial payers submitted claims in 2022 for their commercial plans and Medicare Advantage plans, along with Medicaid and Medicare FFS.

This is the final installment of a series focusing on CO APCD data submitted by payer line of business – commercial health plansMedicaid, and Medicare Advantage and Medicare FFS. The data in each line of business has different nuances that are helpful to be aware of when using the CO APCD.

Medicare Advantage vs. Medicare Fee-For-Service

When we talk about Medicare claims, it’s important to specify which type we are talking about. There are two types of Medicare coverage: Medicare Fee-For-Service (FFS), or traditional Medicare, and Medicare Advantage which can be purchased and is administered through commercial health plans. CIVHC is one of the few organizations that collects both Medicare FFS and Medicare Advantage claims and is able to release data on both types.

The difference comes in which services each plan covers. There are four central parts, or coverage types, for Medicare plans:

  • Part A: Provides inpatient/hospital coverage
  • Part B: Provides outpatient/medical coverage
  • Part C: Also known as Medicare Advantage, the alternative way to receive coverage for Part A and Part B
  • Part D: Prescription drug coverage

Under Medicare FFS, which is administered by the Centers for Medicare & Medicaid Services (CMS), parts A and B are included and you have the option to join a separate program to receive part D coverage. There are also options to purchase supplemental Medicare FFS plans to cover care outside of regular FFS coverage. Medicare Advantage is considered a “bundled” plan, which includes parts A, B, and D and sometimes includes additional benefits such as vision, hearing, and dental coverage. Some of the common types of Medicare Advantage plans are Health Maintenance Organizations (HMOs), Preferred Provider Organizations (PPOs), and Private Fee-For-Service (PFFS).

The payment process between the plans is also different. While Medicare FFS is paid directly through the federal government, under Medicare Advantage, private plans contract with the government and receive funding for enrollments through CMS.

Medicare FFS Claims Collection in the CO APCD 

CIVHC operates through two different programs to receive and release Medicare FFS data. CIVHC first began collecting Medicare FFS claims data in 2014 through the State Agency Request Program, which allows us to use de-identified Medicare FFS data for public and non-public analyses to serve the state in identifying trends and patterns in health care delivery.

In 2019, CIVHC became one of only a handful of nationally approved organizations to use Medicare FFS data through the Qualified Entity Certification Program. Under the program, CIVHC can release Medicare FFS data when combined with Medicaid and Commercial data to produce public reporting on provider performance, and is able to provide Change Agents with actionable data to improve quality of care.

Medicare FFS Release Schedule Variation 

Medicare FFS claims for medical and pharmacy are submitted on different schedules than the monthly frequency all other submitters follow. As a result, Medicare FFS claims are not available for the complete time period displayed in the CO APCD Insights dashboard and are currently only available in the dashboard through December 2022 for medical claims and December 2021 for pharmacy claims. Similarly, Medicare FFS eligibility records are available through December 2022 only.

Bar chart illustrating the number of unique lives insured by Medicare Fee-for-Service (FFS) in the Colorado All Payer Claims Database (CO APCD) from 2013 to 2023. The chart shows yearly fluctuations, with the highest number of insured lives recorded in 2020 at 712,860 and a significant drop to 349,940 in 2023, reflecting incomplete data as of June 2024.

Bar chart showing the number of unique lives insured by Medicare Advantage in the Colorado All Payer Claims Database (CO APCD) from 2013 to 2023. The data illustrates a steady increase over the years, starting at 287,480 in 2013 and reaching 554,130 in 2023, highlighting significant growth in Medicare Advantage coverage.

Line chart displaying the number of Medicare Fee-for-Service (FFS) payers included in the Colorado All Payer Claims Database (CO APCD) from 2013 to 2023. The chart starts with 10 payers in 2013, peaks at 14 payers between 2014 and 2016, and gradually declines to 12 payers in 2023, highlighting trends in Medicare FFS payer participation over the years.

Line chart illustrating the number of Medicare Advantage payers included in the Colorado All Payer Claims Database (CO APCD) from 2013 to 2023. The chart shows a starting count of 10 payers in 2013, a dip to 9 in 2014, followed by an increase to 12 payers in 2020 and 2022, before declining to 10 payers again in 2023. This visual highlights changes in Medicare Advantage payer participation over the years.

Medicare FFS does not offer dental coverage and therefore it is not available as a coverage type for Medicare. It is also important to note that under Medicare FFS, commercial payers pay for Part D coverage, meaning the number of payers under Medicare FFS in the CO APCD appears higher.
