Most dental practices are leaving money on the table—simply because they don’t know how to bill medically necessary procedures to medical insurance. If you’re only submitting claims to dental payers, you’re likely underutilizing a powerful revenue stream.
Whether you’re an oral surgeon performing jaw surgery or a general dentist tackling obstructive sleep apnea cases, medical insurance can cover those procedures—if you bill them correctly.
Let’s break it down, step by step.
Why Bother With Medical Billing for Dental Services?
It’s simple: some procedures are medical in nature and fall outside what dental insurance traditionally covers. Medical carriers often reimburse for:
- TMJ treatment
- Sleep apnea appliances
- Jaw surgeries
- Biopsies
- Congenitally missing teeth (in some cases)
- Trauma or accident-related care
By correctly coding and submitting to medical insurance, you’re not just helping patients afford care—you’re also increasing revenue and decreasing patient out-of-pocket costs.
Who Can Benefit From This?
Here’s where medical billing for dental becomes game-changing:
- Oral and maxillofacial surgeons
- Pediatric dentists treating congenital defects
- Prosthodontists placing implants post-trauma
- General dentists offering sleep therapy appliances
You don’t have to be a specialist to take advantage. You just have to be prepared.
Step 1: Determine Medical Necessity First
Before anything is submitted to a payer, you need to prove why the service is medically necessary.
Ask yourself:
- Is the condition caused by trauma or a medical diagnosis?
- Does the procedure restore a body function or correct a pathology?
- Is this treatment prescribed by a physician or part of a medical referral?
If your answer is yes to any of these, it may qualify for medical insurance coverage.
Step 2: Verify Medical Insurance Eligibility
Call the patient’s medical insurance carrier directly or check the payer portal. Confirm:
- Active policy status
- Medical benefits for the planned procedure
- Prior authorization requirements
- Deductibles and co-pays
- Out-of-network vs. in-network coverage
This step helps set accurate expectations for reimbursement—and helps avoid wasted time and denied claims.
Step 3: Use the Correct Medical Codes (Not CDT!)
Dental offices are familiar with CDT codes. But medical carriers require ICD-10 diagnosis codes and CPT procedure codes.
Choosing a diagnosis code that properly aligns with a billable CPT code is essential. When medical necessity documentation includes too much detail, too little, or information that doesn’t clearly support the procedure performed, it can lead to billing issues, denials, and delays in reimbursement.
Pro Tip: Use precise ICD-10 codes to connect symptoms or conditions (like jaw pain or headaches) with your treatment plan.
Step 4: Get a Written Referral or Letter of Medical Necessity
This isn’t always required—but it helps.
- If your patient is referred by a physician or specialist, include a copy of the referral.
- Draft a letter of medical necessity that outlines the diagnosis, treatment plan, and functional limitations the patient is facing.
This adds strength to your claim and can help justify the billing to the medical carrier.
Step 5: Obtain Prior Authorization (When Required)
Some procedures—especially surgery or sleep appliances—require pre-approval. Without it, payment will likely be denied.
Every payer is different, so check:
- Authorization timelines
- Clinical documentation required
- Where to submit (fax, online portal, or EDI)
Don’t forget to track responses and approval numbers.
Step 6: Submit the Claim on a CMS-1500 Form
Dental claims go on ADA forms. Medical claims must be submitted on a CMS-1500 form, electronically or via clearinghouse.
Make sure to:
- Use NPI and Tax ID tied to your medical billing entity
- Include place of service (POS) codes
- Attach supporting documentation (chart notes, X-rays, referrals)
If you’re unsure how to fill out a CMS-1500, Triton can guide your team through proper setup and claim formatting.
Step 7: Follow Up Relentlessly
Just because a claim is submitted doesn’t mean it’s approved. You need a follow-up system in place to:
- Track claims by submission date
- Monitor rejections or pending statuses
- Appeal denied claims promptly
Strong follow-up is a cornerstone of effective revenue cycle management—especially for cross-coded procedures.
Common Pitfalls (And How to Avoid Them)
Many dental practices get discouraged because their early claims get denied. Here’s where most go wrong:
- Using dental codes on medical claims
- Failing to prove medical necessity
- Submitting incomplete documentation
- Ignoring prior auth requirements
- Using the wrong billing provider setup (e.g., dental NPI on a medical claim)
These are fixable—and they’re exactly the areas Triton helps with during onboarding and ongoing claim support.
What About In-Network vs. Out-of-Network?
If your dental practice is not credentialed with a medical payer, you may still be able to submit as out-of-network. Just know:
- Reimbursement may be lower
- Patient responsibility may be higher
- Some payers require special agreements
Credentialing with medical payers can be complex, but the long-term ROI is worth it for practices offering regular medically necessary services.
What Happens After You Start Billing?
Expect a learning curve. Early claims might require appeals or clarifications. But over time, the system becomes more predictable.
Here’s what comes next:
- Get claims flowing consistently
- Refine your documentation templates
- Train staff on cross-coding and verification
- Use denial data to improve future submissions
