Your practice lives in the difficult gray area between two massive insurance worlds. If you treat a mandibular fracture or perform a biopsy on a tongue lesion, you are not doing routine dentistry. You are providing surgical care, and your claims should reflect that.
Dastify Solutions provides oral and maxillofacial surgery billing and OMS billing services designed to bridge CDT simplicity and CPT complexity. We specialize in dental medical crossover billing ensuring you get paid the full medical rate for the surgical work you actually do.
Most billing errors in Oral and Maxillofacial Surgery Revenue Cycle Management stem from a single, fundamental misunderstanding: billing a surgical diagnosis like it is a tooth-number procedure.
If you extract a wisdom tooth (D7210) because it hurts, that is dental. If you extract it due to documented pathology such as an odontogenic cyst, infection, or other medically relevant condition, it may qualify for medical coverage when supported by the correct diagnosis coding and clinical narrative.
The rules are different here.
| Concept | Tooth-based, centered on tooth number | Diagnosis-based, centered on ICD-10 and surgical complexity |
|---|---|---|
| Limit | Annual maximums, commonly $1,500 to $2,000 | Deductibles and cost share, but medically necessary surgery is not capped the same way |
| Code set | CDT D-codes are broader | CPT codes are more granular and reflect surgical complexity |
| Narrative | Often minimal | Documentation drives approval, including medical necessity and functional impact |
| Result | Faster payment, lower ceiling | Higher upside, but requires OMS-specific documentation and appeals |
| Denial Risk | Low, payers rarely deny D-codes | Higher without OMS documentation, often recoverable with the right appeal strategy |
Want a fast, practical read on where your billing is currently behaving like dental billing?
The hardest part of OMS billing is not selecting a code. It is choosing the right payer pathway and building the claim so the payer processes it as medical, not dental.
Real-time eligibility verification (EDI 270/271) and benefit discovery to prevent front-end errors.
Facial trauma, including mandible fractures and midface fractures
Pathology, including soft tissue biopsies and tongue lesion biopsies
TMJ disorders, including arthroscopy and open joint procedures
This is where documentation changes the outcome
Impacted Third Molars:We document the pathology (cyst, infection, resorption) to justify medical coverage.
Bone Grafting:Moving from simple "site preservation" to medically necessary ridge reconstruction for functionality.
Dental Implants:These can cross into medical coverage when tied to trauma, tumor resection, or medically documented functional deficits.
CMS allows Medicare Part B coverage for dental services when they are clinically linked to a covered medical procedure.
Pre-surgical dental clearances for organ transplants, cardiac valve procedures, and head and neck cancer treatment planning
Extractions and evaluations that are required so the medical procedure can proceed
Coding for anesthesia in oral surgery is a major audit trigger. We time your anesthesia units down to the minute, ensuring the start/stop times match the surgical narrative perfectly to prevent “concurrent care” denials.
Typically, billing teams often miss the anatomical and documentation granularity required for OMS. Our OMS coding services support the service lines that typically drive the highest value and the highest denial rates.
Maxillofacial Trauma and Reconstruction
Facial fracture claims require precision with operative detail, reduction type, and global package rules. We identify separately billable components and prevent improper bundling. For work-related facial trauma, we manage workers’ compensation OMS claims under state-specific fee schedules, including authorization requirements and lien documentation that differ from commercial payer billing
Oral Pathology and Biopsy Management
Denials often happen when the procedure code and diagnosis do not align with payer policy. We verify documentation, pathology results when applicable, and payer coverage rules before submission. Salivary gland excision (CPT 42410 to 42426), submandibular gland excision (42440), neck dissection for oncology cases (38720 to 38724), and maxillectomy procedures (21032 to 21034) require specific anatomical coding and documentation detail that generalist billers routinely under-code.
Orthognathic Surgery Billing and Prior Authorization
These high-value cases face the highest scrutiny for “cosmetic” exclusions. Our prior authorization team prepares the authorization package that supports functional impairment using the documentation payers expect, including cephalometric analyses, airway studies, and sleep-related findings when relevant.
2026 Electronic Prior Authorization Readiness
Under CMS interoperability and prior authorization API requirements, payers are moving toward FHIR-based electronic workflows. Where electronic prior authorization is supported, we submit complete documentation packages through compliant channels to reduce delays. In many cases, expedited requests can be decided within days rather than weeks, compared with older fax and portal cycles.
Implantology and Bone Grafting
Some payers treat implants as strictly dental, but medically necessary exceptions exist. We document trauma, tumor resection, or medically relevant functional impact and build the claim to support the correct reimbursement pathway.
Some commercial payers are increasing scrutiny on higher-dollar reconstructive claims and may attempt to reclassify them into lower-paying pathways if documentation is thin. We reduce downcoding risk by strengthening the claim file with operative documentation and imaging support, including CBCT reports and key imaging when appropriate through accepted claim attachment workflows and payer portals
The compliance environment for OMS continues to tighten. CMS scrutiny on site-of-service documentation and electronic claims has increased under the 2026 Physician Fee Schedule and CMS-0057-F Interoperability Rule. Our workflows are built to reduce denials, prevent recoupments, and create a defensible record if a claim is audited.
QPA reviews for underpayment patterns
Good Faith Estimate workflows for self-pay patients
IDR batching strategies to improve ROI on disputes
Many payers now require peer-to-peer reviews for procedures that used to auto-approve.
We coordinate scheduling and help ensure the clinical rationale is supported by documentation and appropriate citations.
We use automation to monitor claim status codes and work claims before they are hard-denied, so you are not waiting on a denial letter to find out a claim is stuck.
We document anesthesia time and operative narrative so your claims match the record and concurrent care denials and demands.
We do not ask you to change your workflow. We integrate into OMS-relevant systems and adapt to your practice operations.

We keep the referral relationship intact while coding to the findings. If pathology or a medical diagnosis is identified, we document the clinical change clearly and submit the claim under the appropriate pathway so you are paid for the actual complexity.
Yes. We support GFE workflows based on your fee schedule and required timeframes so you stay compliant under the No Surprises Act.
It comes down to what is documented. A simple extraction is typically forceps only. Surgical extraction documentation often includes flap reflection, bone removal, or sectioning. We audit notes for the operative language that supports the correct code selection.
In specific clinically linked circumstances, yes. Medicare Part B may cover dental services when the dental service is necessary for a covered medical procedure to proceed.
To establish clinical linkage, the record should include:
If you suspect your claims are being underpaid, misclassified, or denied for avoidable documentation reasons, we will audit a sample of your recent claims and show you exactly where the revenue is leaking and why. Dastify Solutions is an oral and maxillofacial surgery billing company built for CPT-level surgical billing, not generic dental processing.
