Estimated total-Medicare patients receiving chronic-care management — beneficiary counts on the base monthly management code — scaled from the fee-for-service record (est.). Counts PATIENTS on the base code; the add-on and complex management codes are excluded so a patient is not counted more than once. The benefit began in 2015. Cells under 11 beneficiaries withheld by CMS.

Chronic-care management — a monthly, between-visit service coordinating care for people with two or more chronic conditions — grew from an estimated 453,000 patients in 2015, its first year, to 3,086,000 in 2024, about 6.8 times as many. On the base code the fee-for-service count grew about 4.9 times — the smaller, per-beneficiary figure; the estimated total is a larger multiple because it also reflects Medicare Advantage's rising enrollment.

A benefit that began in 2015. Medicare began paying for chronic-care management in 2015 — a monthly service for coordinating the care of people with two or more chronic conditions, delivered between office visits.

Uptake grew steeply. An estimated 453,000 patients in 2015 grew to 3,086,000 in 2024, about 6.8 times as many; on the fee-for-service record the base-code count grew about 4.9 times, the smaller per-beneficiary figure. This counts patients on the base monthly code — the add-on and complex codes are left out so no patient is counted twice, which makes it a floor, not every chronic-care-management patient.

A volume record, and an estimate. Why uptake rose is a separate question this page does not answer. The scaled figures are estimates: the calculation assumes Medicare Advantage per-capita use equals fee-for-service; MA plans coordinate care under their own arrangements.

An estimate of total-Medicare chronic-care-management volume on the base monthly code, scaled from the fee-for-service record — a floor, not every CCM patient; not a quality or outcomes measure, and not a statement of why uptake rose.

What this is

Estimated total-Medicare patients receiving chronic-care management (beneficiary counts on the base monthly code), 2015 to 2024, scaled from the fee-for-service record.

What it is not

Not all chronic-care-management billing (the add-on and complex codes are excluded to avoid double-counting a patient), not billed claim lines, not a quality or outcomes measure, and not all-payer. The scaled figures are estimates: the calculation assumes MA per-capita utilization ≈ FFS; MA plans may manage care differently.

How this is counted
Estimated total-Medicare chronic-care-management patients, 2015 to 2024: beneficiary counts on the base monthly management code (patients with at least one CCM month that year), scaled from the fee-for-service record per state and summed. The add-on and complex-CCM codes are excluded so a patient is not counted across codes — which makes this a floor, not all CCM billing. The scaled total is an ESTIMATE — it assumes Medicare Advantage per-capita use equals fee-for-service, so it is not an observation; the assumption-free fee-for-service count and its smaller multiple are reported alongside. Chronic-care management is a monthly, between-visit service for people with two or more chronic conditions; Medicare began paying for it in 2015. Cells under 11 beneficiaries withheld by CMS.
