National Trends in the Adoption of the Collaborative Care Model
SUMMARY – In a first-of-its-kind report, the Meadows Institute commissioned Milliman, an independent global data analysis firm, to conduct a study of the nationwide adoption of the Collaborative Care Model from 2018 to 2023. The report provides vital insights into participation by both providers and patients across the country and offers an unprecedented analysis of coverage through Medicare, Medicaid, and commercial health insurance plans. In addition, a detailed regional analysis reveals hot spots in adoption as well as areas where opportunity exists for future growth.
Project Details
This report provides details on the volume of services, patients, and providers using the Collaborative Care Model, including results for 2018 to 2022 for those covered by Medicare or Medicaid, and through 2023 for those covered by commercial health insurance plans. This comprehensive study relies on healthcare claims and encounters datasets maintained by CMS that include 100% of individuals covered by Original Medicare, Medicare Advantage, Medicaid, or the Children’s Health Insurance Program (CHIP), as well as Milliman’s proprietary research datasets containing the experience of between 59 million and 76 million commercially insured individuals. Together these datasets reflect, on average, the healthcare experience of 219 million individuals each year, or roughly two-thirds of the U.S. population.
Key Findings
In terms of provider participation, the number of distinct providers billing for collaborative care services increased nationally from 2018 to 2022 by a factor of:
- 5.8 times for Original Medicare (from 881 to 5,131 providers)
- 10.0 times for Medicare Advantage (from 568 to 5,660 providers)
- 8.6 times for Medicaid and CHIP (from 629 to 5,389 providers)
- 6.9 times for the commercial market, further increasing to 9.1 times in 2023 (from 545 to 3,741 and 4,972 providers, respectively)
In terms of patient participation, the number of distinct patients receiving collaborative care services likewise increased each year from 2018 to 2022 by a factor of:
- 5.2 times for Original Medicare (from 4,095 to 21,160 individuals)
- 8.0 times for Medicare Advantage (from 2,605 to 20,780 individuals)
- 9.2 times for Medicaid and CHIP (from 3,380 to 30,930 individuals)
- 16.6 times for the commercial market, further increasing to 22.2 times in 2023 (from 1,649 to 27,444 and 36,589 individuals, respectively)
