Which Dental Procedures Can Be Billed to Medical Insurance?

One of the most common questions we hear from dental practices exploring medical billing is simple: what can actually be billed?

The answer surprises most dentists. A wide range of procedures that dental practices perform routinely can qualify for medical insurance reimbursement when the right documentation supports medical necessity. Here's a practical breakdown.

The Golden Rule: Medical Necessity

Before diving into specific procedures, it's worth understanding the governing principle: medical insurance covers procedures when there is medical necessity — meaning the treatment addresses a health condition that goes beyond routine dental care.

The diagnosis drives the coverage. A bone graft is a dental procedure. But a bone graft performed because a patient has periapical pathology — which a radiologist would classify as osteomyelitis — becomes a medically necessary procedure. Same treatment, different framing, different payer.

Understanding this principle is the key to unlocking medical billing for your practice.

Sleep Apnea Appliances

Oral appliance therapy for obstructive sleep apnea is one of the most consistently billable procedures in dentistry. Medical insurance — including most major commercial carriers — covers oral appliances when the patient has a qualifying sleep study showing an AHI (apnea-hypopnea index) of 15 or higher, or 5 or higher with symptoms.

Most carriers require prior authorization before the appliance is fabricated and delivered. The prior auth package typically includes the sleep study, documentation of CPAP intolerance or failure if applicable, and a letter of medical necessity.

The reimbursement rates are significantly higher than what dental insurance pays for the same appliance. Some practices report collecting $1,200 to $1,800 or more for a sleep appliance through medical insurance.

TMJ and TMD Treatment

Temporomandibular joint disorders are a strong candidate for medical billing, particularly when patients present with documented symptoms like chronic jaw pain, headaches, migraines, or limited range of motion.

Phase one treatment — orthotic therapy and occlusal appliances — is commonly covered when medical necessity is established. Phase two treatment — permanent rehabilitation through prosthetics or orthodontics — is harder to get covered but not impossible, especially when the patient has a documented history of neurological symptoms like chronic migraines that have been treated unsuccessfully by other providers.

Patients who have seen neurologists, taken medications for chronic migraines, or tried other conservative treatments before coming to your practice have a strong medical necessity case. That history should be documented thoroughly in your clinical notes.

Botox for Jaw Pain and Bruxism

Botox administered for jaw pain, TMJ-related muscle tension, or bruxism is billable to medical insurance through many carriers — and the reimbursement rates are dramatically better than what practices typically collect when offering Botox as a cash-pay service.

Colin Kwasnik's practice in Vermont collects up to $45 per unit from medical insurance for jaw-related Botox. The standard cash rate for cosmetic Botox is typically $12 to $15 per unit. That difference adds up quickly for practices doing meaningful Botox volume for therapeutic indications.

Trauma Cases

Any dental procedure performed as a result of trauma is highly likely to be covered by medical insurance — and in many cases doesn't require prior authorization.

This includes implants, crowns, bridges, endo, fillings, and bone grafts when the treatment is directly tied to a traumatic injury. Patients referred from emergency departments, urgent care clinics, or regional hospitals for trauma-related dental work are among the easiest medical billing cases you'll encounter.

Workers' compensation cases fall into the same category and are typically straightforward to bill.

Bone Grafts and Surgical Procedures

Bone grafts associated with any tooth that has periapical pathology are frequently covered by medical insurance. From a radiologist's perspective, periapical pathology is osteomyelitis — an infection in the bone — and medical insurance treats it accordingly.

When you extract a tooth with periapical pathology and place a bone graft, you're treating an active infection. That clinical framing, supported by your documentation and radiographs, makes a compelling case for medical necessity.

Other surgical procedures that can qualify include:

• Extractions and socket debridement when infection is present

• Procedures related to underlying medical conditions — autoimmune disorders, uncontrolled diabetes, drug-related tooth loss

• Surgical stents for implants (often billed similarly to night guards or orthotics)

• Biopsies and pathology

• Procedures on patients with systemic diseases where oral health directly impacts medical management

Night Guards

Night guards for bruxism and TMJ-related conditions are covered by many carriers, particularly Blue Cross Blue Shield. The documentation requirements are relatively straightforward — a diagnosis of bruxism or TMD and clinical notes supporting the need for the appliance.

This is one of the more accessible starting points for practices new to medical billing because the prior authorization requirements are less involved than sleep appliances and the documentation is simpler.

Periodic and Limited Exams

Even routine exams can be billed to medical insurance in many cases. The reimbursement rates for exams through medical insurance are often two to three times higher than what dental insurance pays for the same exam.

A periodic exam billed to dental insurance might pay $50 to $90 depending on your contracted rate. The same exam billed to medical insurance can pay $120 or more — and in many cases you can bill both dental and medical for the same encounter, with medical as primary and dental as secondary.

What Requires Prior Authorization?

Prior authorization requirements vary by carrier and procedure, but generally speaking you should expect to obtain prior auth for:

• Sleep apnea appliances (almost universally required)

• TMJ and airway procedures

• Night guards (varies by carrier)

• Elective surgical procedures

Trauma cases and emergency-related procedures typically do not require prior authorization. Hospital and ED referrals are usually straightforward to bill without prior auth.

Documentation Is Everything

Regardless of the procedure, the quality of your documentation determines whether a claim gets paid or denied.

Medical insurance carriers want to see clear clinical evidence of medical necessity — specific findings, objective measurements where applicable, a clear link between the diagnosis and the treatment, and a narrative that tells the clinical story of why this procedure was necessary for this patient's health.

A vague clinical note will get a claim denied. A detailed note that directly supports the ICD-10 codes on the claim will get it paid.

Where to Start

If you're new to medical billing, the easiest starting points are trauma cases and night guards — lower documentation burden, fewer prior auth requirements, and relatively predictable reimbursement.

From there, adding sleep apnea billing is a natural next step for practices already doing appliance therapy. The prior auth process has a learning curve but the reimbursement rates justify the effort significantly.
