D6050 is the CDT code for the surgical placement of a transosteal implant — a specialized fixture that passes entirely through the mandible to anchor a prosthesis. It is a rare, complex approach used in select cases of severe bone loss.
Informational only — confirm the official CDT descriptor and your payers' rules independently. This is general guidance, not billing, coding, or clinical advice.
When to Use the D6050 Code
Report D6050 when a transosteal (transmandibular) implant is surgically placed through the lower jaw — typically a framework or set of pins passing from the inferior border of the mandible up through the bone. This approach is reserved for severe mandibular resorption where conventional implants are not feasible, and it is performed in a hospital or surgical setting by specialists. It is uncommon in modern practice.
Distinguish it by implant pathway. D6010 is an endosteal implant placed into the bone. D6040 is an eposteal implant resting on the bone, under the periosteum. D6050's defining feature is that the implant passes through the full thickness of the mandible. The supported prosthesis is reported separately.
Documentation & Clinical Scenarios
Given its complexity and rarity, D6050 demands robust documentation:
- The arch and the severity of resorption justifying a transmandibular approach.
- A detailed narrative describing why endosteal and other options are not viable.
- Advanced imaging (CBCT) and surgical planning records.
- The surgical setting and date, since these cases are often performed under general anesthesia.
Bill separately, where applicable: the prosthesis, any abutments, anesthesia/facility components per their own rules, and any adjunctive surgery. D6050 covers placement of the transosteal implant only.
Insurance & Billing Tips
- Expect significant review. Transosteal implants are rare and high-cost, so payers typically require extensive documentation.
- Establish medical necessity with imaging and a narrative explaining why all conventional approaches fail.
- Verify coverage, maximums, and whether the approach is covered at all before treatment.
- Coordinate facility and anesthesia billing separately, as these cases are often hospital-based.
- Anticipate alternate-benefit handling toward a more common tooth-replacement option.
- Appeal denials with the complete surgical, imaging, and planning record.
Example Case
A patient with profound mandibular atrophy and a long history of failed dentures is evaluated by an oral surgeon. Endosteal implants and grafting are not feasible, and a transmandibular implant is planned in a hospital setting. After CBCT-based planning, the surgeon places the transosteal framework through the mandible under general anesthesia. The placement is reported as D6050 with a detailed narrative and imaging establishing medical necessity, while facility, anesthesia, and the eventual prosthesis are billed under their own codes and rules. Benefits were confirmed in advance.

Frequently Asked Questions
What's the difference between D6050, D6040, and D6010?
The three differ by how the implant relates to the bone. D6010 is endosteal — placed into the bone. D6040 is eposteal — a framework resting on the bone under the periosteum. D6050 is transosteal — passing through the full thickness of the mandible. D6050 is the rarest and most complex of the three, reserved for severe mandibular resorption.
Does D6050 include the prosthesis?
No. D6050 covers only the surgical placement of the transosteal implant. The prosthesis it ultimately supports, along with any abutments, is reported separately under its own codes. Facility and anesthesia services, common with these hospital-based surgeries, are also billed under their own rules rather than within D6050.
Will insurance cover a transosteal implant?
Coverage is uncommon and heavily scrutinized. Because transosteal implants are rare and used only in extreme cases, many plans require extensive documentation of medical necessity or apply an alternate benefit toward a more standard option. Verify coverage, maximums, and any facility-related rules well before treatment, and prepare the patient for a likely out-of-pocket portion.
Do I need a pre-authorization for D6050?
Almost always. Given the procedure's rarity, cost, and surgical complexity, submit a pre-authorization with advanced imaging, surgical planning, and a narrative explaining why conventional implants are not viable. Establishing medical necessity and confirming coverage — including facility and anesthesia handling — ahead of time is essential to a clean claim and an accurate patient estimate.
