Dental billing services
Billing for dental offices that want complete insurance claims sent the first time and medical crossover procedures billed to the right plan.

Why dental billing takes specialty knowledge
Dental billing runs on CDT codes, the ADA claim form and benefit plans with annual maximums, frequency limits and waiting periods. A crown or scaling and root planing claim without X-rays, charting and a narrative is often pended or denied. Plans downgrade posterior composites to amalgam fees, limit bitewings and cleanings by calendar or benefit year, and require pre-determinations for major work.
Some dental procedures belong on a medical claim instead, coded with CPT and ICD-10 on the CMS-1500. Examples include oral surgery after trauma, biopsies and oral appliances for obstructive sleep apnea. SFA Solutions handles both sides. We verify benefits and frequencies before the appointment, attach the right images and narratives, send pre-determinations for major treatment, and bill qualifying procedures to medical insurance when the plan and documentation support it.
Common codes we work with in dental
| Code | Description |
|---|---|
| D0120 | Periodic oral evaluation, established patient |
| D0150 | Comprehensive oral evaluation, new or established patient |
| D0274 | Bitewings, four radiographic images |
| D1110 | Prophylaxis, adult |
| D2740 | Crown, porcelain or ceramic |
| D4341 | Periodontal scaling and root planing, four or more teeth per quadrant |
| D7140 | Extraction, erupted tooth or exposed root |
| D7210 | Surgical extraction of erupted tooth requiring removal of bone or sectioning of tooth |
CPT is a registered trademark of the American Medical Association. Payer rules vary; we check each payer's current policy.
Where dental practices lose revenue
Frequency limits and downgrades
Most plans limit periodic exams (D0120) and adult prophylaxis (D1110) to twice per benefit period and bitewings (D0274) to once per year, but the exact rules vary by plan. Many plans pay posterior composites at the amalgam rate under an alternate benefit clause. Checking history and limits before the visit lets your team quote the patient's portion accurately.
Documentation for major procedures
Crowns such as D2740 usually require a pre-operative X-ray and a narrative explaining why a filling will not work. Periodontal scaling and root planing (D4341 for four or more teeth per quadrant) requires current probing depths and bone loss on X-rays. Missing attachments are the most common reason dental claims are delayed.
Medical crossover claims
Procedures related to trauma, infection, biopsy, TMJ disorders or sleep apnea may be covered by the patient's medical plan. These claims use CPT or HCPCS codes, ICD-10 diagnoses and the CMS-1500 form, and some require a physician's order or a sleep study. Billing medical first, where appropriate, can reduce what the patient pays out of pocket.
Coordination of benefits
Patients with two dental plans, or a dental and a medical plan for the same procedure, need the primary and secondary order confirmed before billing. Some dental plans apply non-duplication clauses that reduce or eliminate the secondary payment. We confirm the order and file the secondary claim with the primary EOB attached.
What else affects dental revenue
A/R challenges in dental practices
Dental A/R usually ages for three reasons: claims pended for missing X-rays, perio charting or narratives, patient balances that appear when a plan applies its annual maximum or a downgrade, and medical crossover claims that bounce between the dental and medical plan. A pre-determination is an estimate, so the patient portion can change when the claim is processed. We follow up on pended claims by attachment request, not just by date, and flag downgrades so patient statements match the EOB.
Credentialing considerations
Dentists credential with dental networks such as Delta Dental, MetLife, Cigna Dental and Guardian separately from any medical plan. Billing medical crossover procedures requires enrolling with the patient's medical plans as well, and some medical payers will not accept claims from a dentist who is not in network with them. Many PPO networks also lease their fee schedules to other plans, so it helps to know which networks you joined and which ones you are being paid through.
Payer considerations
Dental plans range from PPO to DHMO capitation plans that pay a monthly amount per member plus copays, and Delta Dental's PPO and Premier networks have different fee schedules. Traditional Medicare covers dental care only in limited situations tied to covered medical treatment, such as dental exams before an organ transplant or certain cardiac procedures, while many Medicare Advantage plans offer supplemental dental benefits through a separate dental vendor. Medicaid dental coverage for adults varies widely by state and is often run by a dental managed care plan.
Dental coding details that affect payment
ICD-10 considerations
Most dental plans do not require diagnosis codes on the ADA form. Medical crossover claims do, and some dental plans ask for them on periodontal and surgical work. Periodontitis codes were expanded to show extent and severity, such as K05.312 (chronic periodontitis, localized, moderate) and K05.323 (chronic periodontitis, generalized, severe), which should match the charting. Caries codes in K02 identify surface and depth, and dental trauma claims use S02.5 (fracture of tooth) with a 7th character plus external cause codes. Oral appliances for sleep apnea need G47.33 (obstructive sleep apnea) supported by a sleep study.
Modifiers to watch
| KX | Used on Medicare oral appliance claims (E0486) when the coverage criteria in the DME policy are met, and by CMS on dental services linked to a covered medical treatment. |
|---|---|
| GY | Added on a Medicare claim for a statutorily excluded dental service when the patient's secondary plan needs a Medicare denial first. |
| GA | Applied on a medical claim when a signed ABN is on file for a service the practice expects Medicare to deny. |
| 25 | Used on a medical crossover claim when an evaluation is separately documented on the same day as an oral surgery procedure billed under CPT. |
Global periods
Dental plans do not use the Medicare 0, 10 and 90-day global periods, though most include routine postoperative checks in the fee for procedures like D7140 and D7210. When oral surgery is billed to medical insurance under CPT, the code's medical global applies, such as 90 days on many facial fracture repairs.
Medicare considerations
Traditional Medicare pays for dental services only when they are inextricably linked to a covered medical treatment, and CMS asks for modifier KX on those claims to show the link is documented. The dentist must be enrolled in Medicare to bill those services, and Medicare Advantage dental benefits are usually handled by a separate dental vendor with its own fee schedule and network.
Dental billing KPIs to track
- Claims pended for attachments. Missing X-rays, perio charts and narratives are the main cause of dental payment delays, so this rate shows how complete claims are at submission.
- Alternate benefit adjustment amount. Tracking downgrades such as composite to amalgam helps the front desk quote accurate patient portions.
- Pre-determination turnaround. Slow pre-determinations delay major treatment, so the time from request to response affects scheduling and case acceptance.
- Medical crossover payment rate. This shows whether procedures that qualify for medical coverage are being billed to the medical plan with the right codes and records.
Dental billing audit checklist
- Verify frequency history for exams, prophylaxis and bitewings before the appointment.
- Confirm crown and SRP claims include dated X-rays, perio charting and a narrative.
- Check that perio diagnosis codes match the probing depths in the chart when a plan requests them.
- Review secondary claims for the primary EOB and any non-duplication clause.
- Confirm medical crossover claims use CPT, ICD-10 and the CMS-1500 with any required physician order or sleep study.
- Compare patient statements against the EOB for downgrades and annual maximums.

Dental billing questions
Can dental procedures be billed to medical insurance?
Some can, such as treatment after trauma, biopsies, certain oral surgery and oral appliances for sleep apnea. These are billed with CPT or HCPCS and ICD-10 codes on the CMS-1500, and the medical plan's coverage rules apply.
Why was my crown claim denied?
Common reasons include missing X-rays or narratives, a replacement within the plan's frequency window, or a missing tooth clause. We review the denial, add what is missing and resubmit or appeal.
What is a pre-determination?
It is an estimate from the dental plan of what it will pay for planned treatment. Final payment can still change, since the plan applies limits and eligibility when the claim is filed. It helps patients understand their portion before major work begins.
How do you handle patients with two dental plans?
We confirm which plan is primary, bill it first, then file the secondary claim with the primary EOB. We also check for non-duplication clauses that change what the secondary plan will pay.
Do you work with dental Medicaid plans?
Yes, where your practice is enrolled. Adult dental benefits under Medicaid vary widely by state, so we check coverage for each patient before treatment.
