Oral surgery sits on the line between dentistry and medicine, and so does its billing. The same practice may bill a dental plan for an extraction in the morning and a medical plan for a biopsy or a facial fracture in the afternoon, on different claim forms, in different code sets, under different rules. Maximum Billing handles oral and maxillofacial surgery billing on both sides of that line, so procedures that should be paid by medical insurance are actually billed to it, and dental claims go out complete the first time.
We bill for oral surgery practices in twelve states, including Florida and Texas. Schedule a consultation or call 800-820-0364.
Why Oral Surgery Billing Is Different
General dental billing is built around one claim form, one code set, and dental plans with annual maximums. Oral surgery breaks every one of those assumptions:
- Two payer types. Many oral surgery procedures can be billed to medical insurance, dental insurance, or both, depending on the diagnosis and the patient’s coverage.
- Two code sets. Dental claims use CDT procedure codes. Medical claims use CPT procedure codes and require ICD-10-CM diagnosis codes that establish medical necessity.
- Two claim formats. Dental claims go out on the ADA claim form or its electronic equivalent. Medical claims go out on the CMS-1500 or its electronic equivalent, with place of service codes and, for many procedures, prior authorization.
- Higher dollar amounts. A single surgical case can be worth more than a week of hygiene claims, so a single denial or an unbilled medical claim costs far more.
A billing team that only knows dental claims leaves medical revenue on the table. A team that only knows medical claims struggles with dental plan rules. Oral surgery needs both.
Medical or Dental: Which Plan Gets the Claim?
There is no single rule, because it depends on the diagnosis, the procedure, and the patient’s plans. These are common patterns, not guarantees:
| Situation | Often billed to |
|---|---|
| Routine and surgical extractions for dental reasons | Dental plan |
| Biopsies and removal of lesions | Medical plan |
| Facial trauma and jaw fractures | Medical plan, or auto or workers’ compensation coverage when an accident is involved |
| TMJ disorders | Medical plan, where the plan covers TMJ treatment |
| Infections and abscesses requiring drainage | Medical or dental, depending on the plan and diagnosis |
| Orthognathic surgery | Medical plan, usually with prior authorization |
| Implants and bone grafting | Dental plan, when covered at all |
When a procedure is medically necessary and the patient has both types of coverage, the medical plan is often billed first and the dental plan second. Verifying both plans before surgery is the only reliable way to know. Read more in our guide to billing medical insurance for dental procedures.
The Codes Oral Surgeons Work In
CDT codes for the dental side commonly include:
- D7140 and D7210 for simple and surgical extractions, and D7220 through D7240 for impacted teeth.
- D6010 for endosteal implant placement, D7951 for sinus augmentation, and D7953 for ridge preservation grafting.
- D9222 and D9223 for deep sedation or general anesthesia, and D9239 and D9243 for intravenous moderate sedation, each billed in 15-minute increments.
- D0140 for a limited, problem-focused evaluation and D0364 through D0368 for cone beam CT imaging.
CPT codes for the medical side vary by procedure and anatomic site, and include office evaluation and management visits, biopsy codes such as 40808 for the vestibule of the mouth and 41100 for the tongue, 41800 for drainage of a dentoalveolar abscess, and 20605 for arthrocentesis of the temporomandibular joint. Every medical claim also needs an ICD-10-CM diagnosis code that supports the procedure.
Choosing a code is only half the job. The documentation behind it is what determines whether the claim is paid.
Documenting Medical Necessity
Medical plans pay for what the record proves was necessary. For oral surgery claims, that usually means:
- A clear diagnosis, stated in the chart and coded on the claim.
- Clinical findings, symptoms, and history that explain why the procedure was needed.
- Radiographs or imaging, and pathology reports when a biopsy was taken.
- An operative report for surgical procedures, describing what was done and why.
- For trauma, the date, cause, and circumstances of the injury.
Most medical denials for oral surgery are not about the procedure. They are about a diagnosis code that does not support it, or a record that does not explain it.
Anesthesia and Sedation Billing
Sedation is a significant part of oral surgery revenue and a frequent source of denials. Dental plans may limit when deep sedation or general anesthesia is covered, and many only cover it with certain procedures. Time must be documented from start to finish, because sedation codes are billed by increment. Some medical plans cover anesthesia for dental procedures in specific situations, such as for young children or patients with medical conditions that make office treatment unsafe, and those claims need documentation of the medical reason.
Hospital and Surgery Center Cases
When surgery is performed in a hospital or ambulatory surgery center, the facility bills separately for its services, and the surgeon bills the professional component. Your claim must carry the correct place of service, such as outpatient hospital or ambulatory surgery center rather than office, and the facility and the surgeon’s office need to agree on the authorization and the codes. Mismatches between the facility claim and the professional claim are a common reason one or both are held.
Prior Authorization
Many medical plans require authorization before orthognathic surgery, hospital-based procedures, and some diagnostic imaging. Dental plans often offer a pre-treatment estimate, sometimes called a predetermination, for major procedures such as implants. Neither is a guarantee of payment, but performing an authorized procedure without the authorization number on the claim, or after the authorization has expired, is one of the most avoidable denials in oral surgery billing.
Trauma, Accidents, and Third-Party Payers
Facial injuries from car accidents, falls, sports, or work add another layer. Auto insurance or workers’ compensation may be primary, and the patient’s health plan may deny until that coverage is resolved. Accident claims need the date and cause of injury captured at intake, and they often move slowly, so they need steady follow-up to be paid.
Implants and Bone Grafting
Implants and grafting are among the highest-value procedures an oral surgeon performs and among the least consistently covered. Dental plans may exclude implants entirely, cover them only after a waiting period, apply a missing tooth clause, or pay an alternate benefit toward a less costly option. Verifying coverage and submitting a predetermination before treatment lets you give the patient an accurate estimate, and keeps a large balance from becoming a collections problem later.
Credentialing With Medical Plans
Billing medical insurance in network requires the surgeon to be credentialed with those medical plans, separately from any dental plan participation. Many oral surgery practices are well contracted on the dental side and have never enrolled with the medical plans their patients carry, which turns every medical claim into an out-of-network claim. We help oral surgeons enroll with medical payers and keep those enrollments current. Learn more about our credentialing and payer enrollment service.

Oral Surgery Billing in Florida and Texas
Payer mix changes the work. In Florida, Medicare Advantage plans with dental benefits and Medicaid dental plans shape many practices’ claims. In Texas, a large self-pay population and Medicaid and CHIP dental programs change how estimates, authorizations, and collections are handled. For the state details, see our Florida dental billing and Texas dental billing pages, or our main dental billing services page.
Referrals, Pathology, and the Rest of the Care Team
Oral surgery rarely happens in isolation. Patients arrive on referral from general dentists and orthodontists, biopsies go to an outside pathology lab, and complex cases may involve a hospital, an anesthesia provider, and a restorative dentist who places the final crown on an implant. Each of those parties bills separately, and the claims have to tell a consistent story. The referral should be documented, the pathology report should be in the record before a medical claim for the biopsy goes out, and the diagnosis on your claim should match the one on the facility’s. When those pieces line up, claims move. When they do not, payers hold the claim until they do.
What to Look For in an Oral Surgery Billing Company
Revenue cycle management for oral surgeons is a narrow specialty, and most dental billing companies only cover part of it. Before you choose one, ask:
- Do you bill medical insurance, or only dental? If the answer is dental only, every medically billable procedure you perform will keep going to the wrong plan or not being billed at all.
- How do you decide which plan to bill first? You want a process that looks at the diagnosis and both plans for each case, not a single rule applied to every patient.
- Who handles prior authorizations and predeterminations? These should be requested before surgery, tracked, and attached to the claim.
- What happens to a denied surgical claim? High-value claims deserve a prompt, documented appeal with the operative report and imaging, not a resubmission and a hope.
- What will you report to us? Ask for payments, outstanding claims, and denial reasons broken out by medical and dental payers.
Frequently Asked Questions
Can oral surgeons bill medical insurance?
Yes. Many oral and maxillofacial procedures, including biopsies, trauma care, and treatment of infections or TMJ disorders, can be billed to medical insurance when the diagnosis and documentation support medical necessity.
Do you bill both CDT and CPT codes?
Yes. We code the dental side in CDT and the medical side in CPT with ICD-10-CM diagnosis codes, and choose the correct claim form for each payer.
Which plan should be billed first when a patient has both medical and dental coverage?
For medically necessary procedures, the medical plan is often primary, with the dental plan billed second. The answer depends on the plans, so we verify both before surgery.
Do you handle sedation and anesthesia billing?
Yes, including time-based sedation codes and the documentation dental and medical plans require.
Can you help us get credentialed with medical plans?
Yes. Medical payer enrollment is part of our credentialing service, so your medical claims can be billed in network.
Which states do you serve?
We work with practices in twelve states: Colorado, Connecticut, Florida, Georgia, Illinois, Missouri, New Jersey, New York, North Carolina, Pennsylvania, South Carolina, and Texas.
