The Colorado All Payer Claims Database (CO APCD) contains over 1.3 billion claims, with more added every month. These claims are 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.

The CO APCD holds information for over 70% of insured individuals in Colorado with medical coverage, representing over 5.6 million lives in total across all coverage types (medical, dental and pharmacy). As of this post, 33 commercial payers submitted claims in 2025 along with Medicaid and Medicare FFS.

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

Managing Medicaid in Colorado

The Department of Health Care Policy and Financing (HCPF) administers Health First Colorado (Colorado’s Medicaid program). Health First Colorado provides physical, dental, and mental health benefits to qualifying adults and pregnant women as well as children under 18 through the Child Health Plan Plus (CHP+). To help facilitate these benefits, HCPF divided the state into regions and designated organizations in each called Regional Accountable Entities (RAEs) to help patients navigate the system and access services. Additionally, some members opt to enroll in Managed Care Organizations (MCOs), which may offer enhanced care coordination, additional services, or a more integrated provider network compared to the standard RAE model. HCPF and the health plans who act as MCOs or RAEs submit claims for Medicaid members to the CO APCD each month.

When considering Medicaid submissions, CIVHC employs the same methodology as when calculating lines of business within commercial “payer families.” The MCOs and RAEs are considered submitters to the CO APCD while Medicaid is the overarching payer.

Line graph titled "Medicaid Submitters in the CO APCD by Calendar Year, 2013 - 2024" showing the number of Medicaid data submitters to the Colorado All Payer Claims Database (CO APCD) over time. The graph starts at 7 submitters in 2013 and increases to 9 in 2014 and 2015, then rises to 11 in 2016. From 2016 to 2021, the number of submitters remains steady at 11. In 2022, the number peaks at 12, followed by a drop to 10 in 2023, and a slight increase to 11 in 2024. The trend reflects a period of stability with minor fluctuations in recent years.

Medicaid Members in the CO APCD

Approximately 26% of Coloradans receive health care services through Medicaid compared to 23% for people with commercial insurance. In 2024, 1.8 million unique individuals were covered under Medicaid programs, and from 2013-2024, the CO APCD includes nearly 5.1 million unique Medicaid members. The CO APCD collects 100% of the claims from Medicaid members in Colorado, making it one of the most complete payer data sets in the database. The robust nature of the Medicaid data set makes it a relatively straightforward asset to use and analyze, unlike commercial data which is subject to self-insured employer submission restrictions or Medicare Fee-For-Service, which can only be used in specific situations.

Bar chart titled "Unique Lives Insured by Medicaid in the CO APCD Through 2024" showing the number of unique individuals with Medicaid coverage captured in the Colorado All Payer Claims Database (CO APCD) from 2013 to 2024. The chart begins at 1 million in 2013 and increases to 1.4M (2014), 1.6M (2015 and 2016), 1.7M (2017 and 2018), then slightly decreases to 1.6M (2019 and 2020). It rises again to 1.7M in 2021, peaks at 1.9M in 2022 and 2M in 2023, before dropping slightly to 1.8M in 2024. The overall trend shows steady growth with recent peaks likely influenced by public health or policy shifts.

There are some crucial nuances in how Medicaid pays providers and what is included in the claims submissions that are important to note. Medicaid pays hospitals supplemental payments outside of the typical fee-for-service claim payment, and CIVHC receives a separate annual file indicating additional inpatient payments. These additional payments are included in some of our public reports, such as the per-person-per-year cost information in the Community Dashboard, but may not always be reflected in other reports. In addition, Medicaid pays for services that are not covered by commercial payers (e.g., long-term care services and nursing facilities), so it is important to keep this in mind when comparing Medicaid inpatient costs with inpatient costs from other payer types in our public reports.
