Why Dental Practices Outsource Medical Billing
Most dental offices have billing staff trained exclusively in CDT coding and dental insurance workflows. Adding medical billing requires CPT coding expertise, ICD-10 diagnosis code knowledge, CMS-1500 claim form proficiency, and familiarity with medical insurance benefit structures. Rather than retrain existing dental billing staff or hire a separate medical biller (salary $40,000 to $55,000 plus benefits), many practices outsource medical billing to a company that specializes in dental-medical crossover claims. The outsourcing decision is driven by the specialized knowledge required and the relatively low volume of medical claims compared to dental claims.
Essential Vendor Capabilities
A dental medical billing vendor must demonstrate competency in both code systems: CDT for coordination with the dental billing workflow and CPT for medical claim submission. The vendor should handle medical insurance verification, prior authorization for services that require it (sleep apnea appliances, TMJ surgery, general anesthesia), medical claim coding and submission, denial management and appeals, and patient billing for medical cost-sharing amounts. Ask for the vendor denial rate specifically on dental-origin medical claims, which should be below 12%. General medical billing companies without dental expertise often produce denial rates above 20% on dental crossover claims.
Credentialing Support
The most valuable service a dental medical billing company provides is medical insurance credentialing. The vendor should manage the entire credentialing process: identifying which medical payers to credential with based on your patient mix, completing the applications, tracking the status, and notifying you when credentialing is approved. Credentialing maintenance (re-credentialing every 2 to 3 years, updating demographic information) should also be included. Without proper credentialing, no medical claims can be paid, making this the foundation of the entire program.
Pricing Models
Dental medical billing outsourcing is priced at 8% to 12% of medical insurance collections, higher than general medical billing (4-7%) because of the lower claim volume per practice and the specialized knowledge required. Some vendors offer flat monthly fees ($500 to $1,500 per dentist) which may be more cost-effective for practices with higher medical billing volume. Evaluate total cost against expected revenue: if the vendor charges 10% but enables $6,000 per month in medical revenue that was previously uncollected, the net gain is $5,400 per month.
Workflow Integration
The vendor must integrate with your dental practice management software to receive encounter information. Most dental-medical billing companies accept data through a portal upload, direct EHR integration, or daily batch file transfer. The workflow should not require your clinical staff to change their documentation habits significantly. Ideally, the vendor reviews each day completed encounters, identifies medically billable services, requests any missing documentation from the clinical team, and submits the medical claim without the provider needing to initiate the process.
Performance Expectations and Monitoring
Set clear performance expectations in the service agreement: medical claim submission within 48 hours of receiving encounter data, denial rate below 12%, days in AR below 40, and monthly revenue reporting by service type. The vendor should provide a monthly report showing: total medical claims submitted, total collected, denial rate by CARC code, aging report, and a list of encounters reviewed but not billed (with the reason). Review this report monthly and address any metric that falls below the agreed standard. A good vendor should be increasing your medical revenue quarter over quarter as they optimize the billing process and identify additional crossover opportunities.
