Medical Billing for Oral Surgery: Simple Guide and Best Practices

Many oral surgery practices still struggle to get paid on time because claims go to the wrong payer, or the documentation does not prove medical necessity. According to research, 10,000+ dental professionals improve billing for oral surgery, which shows how common these challenges are in clinics like yours. In this blog, we’ll explain what counts as medical, the documents you need, and how to pick the right oral surgery codes.

What Is Medical Billing for Oral Surgeons?

Medical billing for oral surgeons means sending certain oral and maxillofacial surgery claims to a patient’s medical insurance instead of their dental plan. You carry it out when it is a medically required surgical operation rather than dental maintenance. They may include such categories as infected impacted teeth that need to be removed, suspicious lesions-biopsies, TMJ surgery aimed at restoring its functionality, bone post-trauma grafts, and fracture repair.

Why it matters

Medical plans can pay for services that dental plans cap or exclude. Done right, this reduces the patient’s out-of-pocket cost and raises your case acceptance and collections.

Who Should Bill Medical, and When?

Bill medical insurance when a procedure treats an injury, infection, disease, or functional problem. In simple terms, if the surgery protects systemic health or restores normal function, medical billing is usually appropriate. Common qualifying scenarios listed by NiermanPM include impacted third molars with pain or nerve risk, biopsies for possible cancer, TMJ surgery for severe dysfunction, jaw trauma, and sleep apnea surgeries like MMA.

Where Claims Go Wrong and How To Prevent Them

No clear medical necessity
Write a short, direct story in your note. State the symptoms, objective findings, diagnosis, risk if untreated, and why surgery is required. Attach images and any referrals.

Wrong code set
Use CDT only for dental claims. Use CPT and ICD-10-CM when you send to medical. The “cross-coding” step must match the dental service to a medical procedure code and a diagnosis code that proves necessity.

Missing pre-authorization or benefit check
Verify medical benefits. If the payer needs pre-auth, submit your SOAP note, imaging, and referral before treatment.

Place of service not set
Put the correct place of service for office, hospital, outpatient, or ASC on the claim. This helps the payer price the claim correctly.

No follow-up after submission
Track claim status, read the EOB reason codes, and appeal with focused documentation when needed.

How To Bill Medical Step By Step

Step 1. Confirm medical necessity

Under evaluation, disclose the functional problem, risks to be faced, and expected arm outcome of surgery. Simple SOAP notes suffice well: Subjective, Objective, Assessment, Plan.

Step 2. Cross-code correctly

Convert the dental service to the right CPT and ICD-10-CM pair. Add valid modifiers only when required. Keep it tight and accurate.

Step 3. Pre-auth and verify

For surgeries that need authorization, send your notes, imaging, and physician referral if applicable. Save all approvals in the chart.

Step 4. Submit a clean claim

Choose the correct payer. Use exact codes. Attach needed reports. List the place of service. Keep copies of what you sent.

Step 5. Follow up and appeal

Check the payer portal. If denied, identify the reason and resend with the missing element. Most fixes are documentation or code edits.

Which Oral Surgery CPT Codes Appear Often

Your official CPT book is the final word. The goal here is to keep your team thinking in clear categories, so you pick codes that match the work performed.

• Impacted third molars and surgical extractions are performed when there is infection, pain, or nerve risk, and the case is medically necessary. Pair with diagnosis codes that show pathology or functional harm.
• Biopsies and lesion management when you need to rule out serious disease. Include site, size if required, and pathology order in the record.
  TMJ procedures for severe dysfunction that affects opening, chewing, or the airway. Document function limits and failed conservative care.
• Particularly, bone grafting and jaw reconstruction are required following trauma or due to congenital faults, which hamper functionality. Indicate and list the reconstruction plan.
• Trauma care, including fracture repair and lacerations. Clearly record the mechanism of injury, imaging, and fixation method.
  Anesthesia for intraoral procedures is reported with anesthesia CPT when applicable, using correct modifiers per payer policy.
  Use this section as a checklist when you choose codes in your CPT manual and connect them to the right diagnosis codes.

What Documents Make Or Break A Medical Claim

Keep a small packet ready for each case.

• SOAP note that tells the medical story in a few lines
• Imaging, including the X-ray or CBCT, which substantiates the diagnosis.
• Referral, where possible, by a physician or specialist.
• Procedure note that explains what you did and why
• Pre-auth approval when the plan requires it

Why This Process Works?

Because it aligns your claim with how medical payers think. You show a health problem, prove necessity, use the correct oral surgery CPT codes, and submit the claim in a format their systems understand.

FAQs

Can routine extractions go to medical insurance?

Usually no. If the extraction is part of treating an infection, trauma, or another medical condition, then yes, medical can be appropriate with the right documentation.

Do I still need CDT when I bill medical?

Yes, for your dental records, and if you also file a dental claim. For the medical claim, you submit CPT and ICD-10-CM.

What if the plan denies medical necessity?

Read the EOB, fix the gap in notes or codes, and send an appeal with imaging and a clear one-paragraph rationale. Many denials are recoverable.

How can a small team manage all this?

Use a simple checklist for benefit verification, pre-auth, coding, submission, and follow-up. NiermanPM suggests training and software to standardize cross-coding and SOAP output.
