How much does CPT 21215 pay under Medicare Part B?

In the 2024 CMS Medicare Physician and Other Practitioners by Provider and Service file, CPT 21215, repair of the lower jaw bone with bone graft, drew $4,338,970 from 35 billers, 30 of them dental providers. For scale, 1,100 providers billed Medicare Part B for dental and oral surgery services that year for $27.65 million total, under the provider types Dentist and Oral Surgery (Dentist only), though that count comes from a different CMS file with a different unit of analysis.

Is CPT 21215 covered by Medicare everywhere?

No. It appears in exactly one Medicare Administrative Contractor coverage article nationally, Palmetto GBA's A56658, verified against the CMS Medicare Coverage Database bulk export. That article carries a 674-row diagnosis whitelist limited to trauma and ablative cancer surgery. A claim billed with a diagnosis outside that whitelist is denied automatically at the code-payment-edit level.

Does 21215 cover ridge augmentation to support dental implants?

No. Direct query of Palmetto's A56658 diagnosis whitelist shows zero matches for K08.20, K08.21, K08.24, or any other K08 code, alveolar ridge atrophy, and zero matches for any M26 dentofacial anomaly code. Trauma and tumor removal are covered. Ridge augmentation for implant support is not, and is an automatic denial under this policy, not a gray area.

What happens if a practice bills 21215 in a state with no coverage policy?

Noridian JE, which administers California, holds no Cosmetic and Reconstructive coverage policy for these codes at all. That means a diagnosis that would auto-deny under Palmetto's whitelist can pay on first pass in a state with no such policy, with no coverage document a provider could point to as authority if the claim is reviewed later. The absence of a rule is not permission. It is an unpoliced claim that can be recouped on post-payment review.

Is a dentist recognized as a physician for Medicare purposes on facial reconstruction claims?

CMS's National Coverage Determination 260.6 still contains text stating a dentist is not recognized as a physician under Section 1861(r) of the Social Security Act, though CMS addressed this at 87 FR 69664. An auditor may still cite the older NCD language. The safer citation for a qualifying claim is Section 1861(r)(2) directly, together with the Medicare Benefit Policy Manual Chapter 15, Section 150.

CPT 21215 Carries $4.3 Million and One Coverage Policy. Should You Bill It?

Look at the service-line detail behind what dentists and oral surgeons billed Medicare Part B in 2024 and one code dominates it. Not by a little. CPT 21215, repair of the lower jaw bone with a bone graft, drew $4,338,970 from just 35 billers. The question is not whether the money is real. It is whether billing it is safe, and the answer depends on a coverage policy most practices have never opened.

How much money is actually in CPT 21215?

The national number

CPT 21215 accounted for $4,338,970 in 2024, billed by 35 providers, 30 of them dental, in the CMS Medicare Physician and Other Practitioners by Provider and Service file. For scale, the companion by-provider file shows 1,100 providers billed Part B for dental and oral surgery services that year for $27.65 million total, under the provider types Dentist and Oral Surgery (Dentist only). The two are different files with different units of analysis, so the code total is not a percentage of the provider total. The top biller of 21215 and its companion code 21210 collected more than any other dental or oral surgery provider in the country.

Source: CMS Medicare Physician and Other Practitioners, by Provider and Service and by Provider files, 2024. Amounts are Medicare-paid, not submitted charges.

That concentration is not spread across the profession. It sits with a small number of oral and maxillofacial surgeons doing mandible and midface reconstruction, the kind of work that follows trauma or tumor removal, not routine dental surgery.

Where does CPT 21215 actually appear in Medicare coverage policy?

In exactly one place. A direct query of the CMS Medicare Coverage Database bulk article export, current as of article version 42, updated 2026-01-27, shows CPT 21215 listed in a single Local Coverage Article nationally: Palmetto GBA’s A56658. Its companion code 21210, bone graft for nasal or cheek bone repair, appears in two articles, A56658 and CGS’s A59299. Code 21048, lower jaw growth or cyst removal, appears in none.

This is a narrow footprint for a code carrying millions of dollars a year. Most of the country has no published policy addressing it at all, which is a different situation than broad coverage, not a better one.

What does Palmetto’s coverage article actually require?

A56658 states its own scope directly: it establishes “limited coverage for facial and maxillofacial procedures,” and the covered CPT codes are paired with a specific diagnosis list that “limit the use of reconstructive surgeries of the head and neck to the repair of injuries due to trauma or ablative surgery.” The article states plainly that a claim billed with a diagnosis code not on that list “will be denied as not covered.”

The whitelist runs 674 diagnosis codes. Queried directly against the article’s own diagnosis-to-code crosswalk, the leading categories by volume are S01, head injuries, at 141 codes; C44, skin cancer, at 40; C50 at 36; and S05, eye and orbit injury, at 34. This is a trauma-and-cancer list, not a general reconstructive-surgery list.

Does this code cover ridge augmentation for dental implants?

No, and this is the distinction that matters most for a general dental or oral surgery practice. A direct query of the same whitelist for K08.20, K08.21, and K08.24, the codes for atrophy of the edentulous alveolar ridge, and for the M26 dentofacial anomaly family, returns zero matches for either family, at any code within them.

Ridge augmentation performed to support future implant placement is not on the covered list. Billed against this policy, it is not a marginal claim awaiting judgment. It is an automatic denial, enforced as a code-level edit against the diagnosis submitted.

What does covered versus not covered actually look like under A56658?

Diagnosis family	Example use case	Covered under A56658?
S01.xx (head injury)	Traumatic jaw fracture repair	Yes, 141 codes listed
C44.xx / C50.xx (cancer)	Reconstruction after tumor ablation	Yes, listed
S05.xx (eye/orbit injury)	Orbital trauma reconstruction	Yes, 34 codes listed
K08.20 / K08.21 / K08.24 (ridge atrophy)	Ridge augmentation for implant support	No, zero matches
M26.x (dentofacial anomalies)	Corrective jaw surgery for malocclusion	No, zero matches

Why does California make this riskier, not safer?

Noridian JE, which administers Medicare Part B in California, holds no Cosmetic and Reconstructive coverage article for these codes at all. Only five Medicare Administrative Contractors nationally publish one. That absence means a diagnosis that would auto-deny under Palmetto’s whitelist can be submitted in California and pay on first pass, because there is no automated edit to catch it.

That is not a coverage benefit. It is the removal of the control that would otherwise stop the claim before payment, which means the review happens later instead, on post-payment audit, with no coverage document a provider can point to as the basis for having billed it. California accounts for a disproportionate share of national 21215 billing. The absence of a local policy is a plausible mechanism for why, not evidence the claims are safe.

Is a dentist recognized as a physician for this billing?

The underlying eligibility question predates the coverage article itself. National Coverage Determination 260.6 still contains text stating that “a dentist is not recognized as a physician” under Section 1861(r) of the Social Security Act. CMS effectively superseded that reading in the 87 FR 69664 rulemaking, but the older language remains live in the NCD text, and an auditor unfamiliar with the later rulemaking can still cite it.

The more defensible position on a qualifying claim is to cite Section 1861(r)(2) and Medicare Benefit Policy Manual Chapter 15, Section 150 directly, rather than relying on an implicit repudiation of older NCD language that a reviewer may not independently know about.

What should a practice billing 21215 actually check?

Confirm the operative diagnosis code sits inside the trauma-and-cancer whitelist before the claim goes out, not after a denial or an audit letter arrives. If the practice operates in a jurisdiction with no published coverage article, that absence does not substitute for documentation. Keep the trauma or ablative-surgery basis for the procedure in the chart regardless of whether the local MAC would currently catch its absence.

Where this comes from

The 2024 code-level billing figures come from the CMS Medicare Physician and Other Practitioners by Provider and Service Public Use File. The 1,100-provider, $27.65 million scale figure comes from the companion by-provider file for 2024 (R26 P05 V10 D24, filed May 2026), provider types Dentist and Oral Surgery (Dentist only), queried September 2, 2026. Amounts are Medicare-paid, not submitted charges. Because the two files count different things, no percentage of one is computed against the other here. The coverage-policy findings come from a direct query of the CMS Medicare Coverage Database bulk article export (article version 42, updated 2026-01-27), run against the article-to-code and article-to-diagnosis crosswalk tables rather than the rendered web pages, which do not expose the full code lists. No provider or practice named in that dataset is identified here.
