Four in ten Medicare beneficiaries skipped a free preventive visit in 2022 that could have connected them to no-cost screenings for conditions like diabetes, depression, and cognitive decline. The Annual Wellness Visit, covered once every 12 months under Medicare Part B at zero cost to the patient, is designed to build a personalized prevention plan and generate referrals for covered screenings. Yet federal survey data show that 60% of community-dwelling beneficiaries used the benefit that year, leaving roughly 40% without a structured check on their health risks.
Why 40% of beneficiaries still skip a zero-cost visit
The gap between coverage and use has real clinical consequences. The AWV is not a traditional physical exam. It requires a health risk assessment, an updated medical history, a current list of providers, and a written prevention plan with referrals to screenings that Medicare already covers at no additional charge, according to detailed CMS instructions. When beneficiaries skip that visit, they lose the structured trigger that connects them to cancer screenings, cardiovascular risk checks, and cognitive assessments before symptoms appear.
The hypothesis that lower AWV adoption leads to later-stage diagnoses within two years is difficult to test with public data alone, but the logic follows directly from how the visit works. The AWV exists to identify risk factors early and route patients toward covered follow-up tests. Without it, detection depends on whether a patient or provider raises a concern during a sick visit, which shifts the odds toward later discovery. Practices that performed few or no AWVs in 2015 were disproportionately those serving underserved populations, according to a Health Affairs study on practice-level adoption. That pattern suggests the screening gap falls hardest on patients who already face higher disease burdens.
Federal data and billing records trace a slow adoption curve
The most recent federal benchmark comes from the Medicare Current Beneficiary Survey, which reported that 60% of Medicare beneficiaries living in the community had an annual wellness visit in 2022. That figure represents real progress from the benefit’s early years. A study published in the Journal of General Internal Medicine documented that the total number of AWVs grew steadily between 2011 and 2018, but the increase did not reach all corners of the health system evenly. Smaller primary care practices and clinics caring for low-income or rural patients have been slower to integrate AWVs into their workflows, leaving many beneficiaries without a clear invitation to schedule the visit.
CMS tracks the visits through two billing codes: HCPCS code G0438 for a beneficiary’s initial AWV and G0439 for each subsequent annual visit. Patients pay nothing when the provider accepts assignment, a detail confirmed on the beneficiary-facing Medicare.gov page that explains yearly wellness coverage. That same page warns that if a provider performs additional tests or services during the same appointment that fall outside preventive coverage, the patient may owe coinsurance or a deductible. This billing nuance creates confusion: some beneficiaries avoid the visit because they fear unexpected charges, while others schedule it but leave with a surprise bill after the provider adds diagnostic work.
Provider behavior also shapes uptake. AWVs require time-consuming documentation and advance planning, including completion of a health risk assessment before or during the visit. Some clinicians report that the payment does not fully compensate for the staff time needed to collect questionnaires, review medications, and create a written prevention plan. As a result, they prioritize problem-focused visits that address immediate complaints and generate higher relative value units, unintentionally sidelining preventive care that could avert future illness.
Unanswered questions about awareness and access
Several gaps in the evidence make it hard to pinpoint exactly why 40% of eligible beneficiaries do not use the AWV. CMS publishes technical coverage guidance for providers, but there is limited public data on how well beneficiaries understand the benefit. Surveys suggest many older adults conflate the AWV with a “free physical,” while others assume that if they already see a doctor regularly, they are receiving all covered preventive services. In reality, unless the visit is billed under the AWV codes and includes the required elements, the patient may miss systematic screening for depression, fall risk, or cognitive changes.
Access barriers further complicate the picture. In areas with few primary care clinicians, practices may not have capacity to add dedicated preventive visits, and homebound or transportation-limited beneficiaries may struggle to reach the office even when they are aware of the benefit. Language differences and low health literacy can make mailed notices or portal messages ineffective. The Health Affairs findings that low-AWV practices disproportionately serve underserved groups raise the possibility that the very populations at highest risk for chronic disease are least likely to be offered or encouraged to schedule an AWV.
Policy analysts argue that closing this gap will require better communication and simpler rules. Clearer explanations of which services are free, stronger encouragement from clinicians, and outreach tailored to high-risk communities could move more beneficiaries into regular preventive care. The AWV alone cannot eliminate disparities in late-stage diagnosis, but the persistent 40% nonuse rate underscores how much untapped potential remains in a benefit Medicare already pays for in full.
