How much did Medicare pay these providers combined?

$8,303,819 paid nationally across both provider types in 2024, against $28,134,123 submitted and $10,988,683 allowed. The allowed-to-submitted ratio, 39.1%, reflects standard fee-schedule adjustment and is not a denial rate; this dataset contains no denial data at all.

Is this market growing or shrinking?

Neither cleanly. Provider count and paid dollars were roughly flat from 2020 to 2023 ($9.98M to $10.76M, excluding a since-resolved billing anomaly), then paid dollars fell 37.1% in 2024 to $8.3M. The honest baseline is $8.3M in 2024, not the higher 2023 figure, which included a cluster of jaw-graft billing that vanished from the 2024 file entirely and should not be treated as a recurring part of the market.

How concentrated is the billing among these 629 providers?

Heavily. The top 100 providers collected 74.6% of all paid dollars. The median provider collected $3,118 for the year, one or two cases' worth, while the mean was $13,202, more than four times the median. A small number of providers operate this as a real revenue line; most of the 629 are billing occasionally.

What are these 629 providers actually billing for?

Office visit E/M codes (99213, 99214, 99203, 99204) account for 45.4% of all paid dollars and are billed by 100 to 172 providers each, a broad base. The high-dollar procedure codes are the opposite: jaw and facial bone-graft repairs, oral pathology exams, and surgical splints are each billed by only 2 to 16 providers nationally. A code billed by 2 providers in the entire country is not a market most practices can enter by simply learning the code; it describes a small number of specific surgical relationships.

Does this include Medicare Advantage?

No. This data is traditional Medicare Part B only. Medicare Advantage now covers more than half of Medicare beneficiaries and has its own dental benefit structure, entirely separate from this dataset. These figures describe a minority of the total Medicare population and should never be presented as the whole Medicare dental market.

Who Actually Billed Medicare for Dental Work in 2024, and For What.

Q: How many providers billed Medicare Part B for dental work in 2024?

629 unique NPIs nationally: 166 classified as Dentist and 463 as Oral/Maxillofacial Surgery, per CMS's Medicare Physician & Other Practitioners by Provider and Service dataset, 2024 data year. This is a complete count of every provider-type row for those two categories, not a sample.

Six hundred twenty nine. That is the complete national count of providers, dentists and oral-maxillofacial surgeons combined, who billed traditional Medicare Part B for dental-related work in 2024. Not a sample, not a segment of a bigger number, the whole thing. Why should a dentist bill medical insurance for dental work at all covers why this lane is codified and legitimate. This piece covers who is actually standing in it, and what that tells a practice deciding whether to enter.

What is the actual size of this market?

629 providers nationally billed Medicare Part B for dental or oral-maxillofacial services in 2024: 166 classified as Dentist, 463 as Oral/Maxillofacial Surgery. Combined paid total: $8,303,819.

CMS’s Medicare Physician & Other Practitioners by Provider and Service dataset covers every paid Part B claim nationally, broken out by provider type. Pulling every row where the provider type is Dentist or Oral/Maxillofacial Surgery for the 2024 data year gives a complete, not estimated, count. Submitted charges were $28.1M, allowed amount $11.0M, and Medicare paid $8.3M. The allowed-to-submitted ratio of 39.1% is ordinary fee-schedule adjustment, the standard gap between what a provider bills and what Medicare’s fee schedule recognizes, not a denial or rejection rate. This dataset carries no information about denied claims at all.

Is this market growing?

The honest answer requires naming a resolved anomaly rather than skipping past it. Paid dollars ran roughly flat from 2020’s $9.98M to 2023’s peak, which on the surface looked like $13.2M but included a cluster of jaw and facial bone-graft billing by a small group of providers that disappeared from the 2024 file entirely. With that cluster removed, the underlying trend was closer to flat: roughly $10M a year. Then in 2024, paid dollars fell to $8.3M, a genuine 37.1% single-year drop that traces almost entirely to specific high-dollar jaw-repair procedure codes going from meaningful volume to zero. Five separate procedure codes in that family dropped to $0 paid nationally in 2024 compared to nonzero totals in 2023.

The right way to describe this market is not growing and not simply falling either. It is small, it is flat-to-shrinking depending on the year measured, and any figure above $8.3M should be treated with the same caution this piece is applying to it now.

Who is actually collecting the money?

Cut	Share of paid dollars
Top 10 providers	29.9%
Top 25 providers	44.6%
Top 50 providers	59.1%
Top 100 providers	74.6%

The median provider among the 629 collected $3,118 in 2024, roughly the value of one or two qualifying cases. The mean was $13,202, over four times the median, which only happens when a small number of high-volume billers pull the average far above what a typical provider actually sees. Three-quarters of every dollar in this market goes to 100 named, NPI-identifiable providers out of 629 total. Most of the remaining 529 are billing occasionally, not operating this as a defined service line.

What are they billing, and does the code you’d want to bill actually have volume behind it?

Office visit evaluation and management codes, 99213, 99214, 99203, and 99204, account for 45.4% of all paid dollars in this market and are billed by 100 to 172 providers each nationally, a genuinely broad base any enrolled provider can reasonably expect to participate in. The picture changes completely at the high-dollar procedure codes. Jaw and facial bone-graft repair codes, oral pathology exams, and surgical splint codes are each billed by only 2 to 16 providers in the entire country. A procedure billed nationally by 2 providers is not a market a new entrant learns their way into by studying the code description. It describes a small number of specific clinical relationships and referral patterns that took years to form.

What does this mean for a practice deciding whether to enter?

The office-visit lane, E/M coding tied to a documented qualifying medical condition, is the realistic entry point: broad enough that 100-plus providers already participate at meaningful volume, and it does not depend on being one of a handful of surgeons nationally who perform a specific graft procedure. The high-dollar procedure codes are not a template to copy. They describe what a small number of specialists already do, not a gap a general practice can step into with correct coding alone.

Where this comes from. All figures are from CMS’s Medicare Physician & Other Practitioners by Provider and Service dataset, 2024 data year, filtered to provider types Dentist and Oral/Maxillofacial Surgery. The dataset excludes Medicare Advantage entirely and contains no denial data. The underlying coverage rule this market operates under is 42 CFR 411.15(i)(3).
