Preventive care billing in Medicare never bounced back. Four years after the pandemic disrupted routine visits, the numbers tell a story of structural contraction, not temporary delay.

Initial Wellness Visits Are in Freefall

Start with the starkest number: initial annual wellness visits (G0438) fell from 853,589 in 2019 to 591,568 in 2020, and then kept falling. By 2023, the count had dropped to 435,826, roughly half the pre-pandemic baseline. This isn't a recovery story with a slow tail. It's a sustained, year-over-year decline across five consecutive data points.

Cervical cancer screening (G0101) followed a similar arc. Services dropped from 820,690 in 2019 to 632,115 in 2020, and by 2023 had only recovered to 676,149, still 17.6% below where they started. For a screening tied directly to early cancer detection, that gap represents real patients who didn't get checked.

One code bucked the trend: subsequent annual wellness visits (G0439) grew from 8,130,935 in 2019 to 9,739,340 by 2023, the only major preventive code to exceed its pre-pandemic baseline. That divergence matters. The Medicare population that was already engaged in the wellness visit cycle continued showing up. The patients who hadn't yet completed an initial visit largely didn't enter the pipeline.

Specialty Recovery Has Been Wildly Uneven

Across provider specialties, the pandemic's billing impact varied by more than 20 percentage points, and recovery has been just as uneven.

Physical Therapists in Private Practice absorbed the largest absolute drop in 2020, losing 26,809,857 services (a 20.2% decline), yet by 2023 had grown 21.9% above 2019 levels. That full recovery reflects a category where demand is durable and patients actively reschedule.

Internal Medicine tells the opposite story. It lost 19,274,843 services between 2019 and 2020, a 14.7% drop, and by 2023 remained 21.6% below its 2019 level. For a specialty that handles the bulk of chronic disease management and preventive care for Medicare beneficiaries, that's not a rounding error. It means fewer annual physicals, fewer medication reviews, fewer early catches.

Orthopedic Surgery sits at the extreme end: 41.1% below 2019 levels by 2023. Ambulance Service Providers were 24.8% below, declining from 154,244,152 services in 2019 to 115,956,750 in 2023. The ambulance figure is particularly notable because it doesn't reflect patient choice to defer care. It reflects a structural change in utilization that has persisted for years.

The Pipeline Problem No One Is Talking About

The divergence between G0438 and G0439 is the most consequential finding in this data. Subsequent wellness visits grew because existing patients kept coming back. Initial visits collapsed because new patients stopped entering the system. By 2023, subsequent visits outnumbered initial visits by more than 22 to 1 (9,739,340 vs. 435,826).

Metropolitan Family Practice providers show how little the provider supply changed: 59,397 providers in 2020, 59,380 in 2023, delivering 69,930,774 and 68,931,500 services respectively. The workforce was essentially flat. The volume drop wasn't a capacity problem on the supply side.

When initial wellness visits fall by nearly half over four years while the provider count holds steady, the implication is that a growing share of Medicare beneficiaries are aging into the program without ever completing a baseline preventive assessment. That assessment is where providers flag undiagnosed hypertension, cognitive decline, and cancer risk. Skipping it doesn't eliminate those conditions. It just delays their discovery, typically until they're more expensive and harder to treat.

Whether the collapse in G0438 reflects patient hesitancy, administrative friction, or a shift in how new Medicare enrollees engage with the system is a question the billing data alone can't resolve. But the trend line is now five years old, and it's still pointing down.
