D7750

Malar and/or zygomatic arch — open reduction (compound/open fracture)

Code Summary

D7750 is the CDT code for the open reduction of a malar and/or zygomatic arch fracture in the compound (open) fracture series — surgically treating a fractured cheekbone (malar/zygoma) and/or zygomatic arch, where the fracture is compound/open (the broken bone exposed to the mouth or outside), by making an incision to access and realign (reduce) it (often with fixation). It parallels D7650 (the simple-fracture malar/zygomatic open reduction) but is in the 'compound fracture' series.

What D7750 means

D7750 covers the open reduction of a malar and/or zygomatic arch fracture in the compound (open) fracture series. "D" is dental, "77" is this oral surgery (compound fracture treatment) group, and "50" is this cheekbone open reduction. It's the compound-series counterpart of D7650 — the open reduction of a cheekbone (zygoma/zygomatic arch) fracture (surgically accessing and realigning it, with fixation as needed), but for a compound (open/exposed) fracture. A compound (open) fracture has the broken bone exposed — communicating with the mouth or outside (through a break in the soft tissue/mucosa). 'Open reduction' (the treatment) means a surgical incision is used to reduce the fracture. (Note the two senses of 'open': the fracture is open/compound — exposed — AND the treatment is open reduction — via a surgical incision.)

So it's surgically realigning and fixing a fractured cheekbone — where the fracture is compound (the bone exposed) — the open reduction treatment, in the compound-fracture series.

A zygomatic fracture can be compound/open if the fractured bone communicates with the mouth or outside — for example, if a zygomaticomaxillary complex fracture involves the maxillary sinus or extends to areas communicating with the mouth, or if there's an associated wound exposing the bone. As with any open fracture, the treatment manages the contamination/infection risk (cleaning, antibiotics, soft tissue care) alongside the fracture reduction/fixation. The open reduction (D7750) surgically realigns the displaced cheekbone (restoring the cheek contour, the orbit if involved, and jaw opening if the arch impinged) and fixes it as needed (plates/screws at the buttresses), as with D7650. It's performed by an oral and maxillofacial (or facial) surgeon, in a hospital/surgical setting, as part of trauma care. For the open/compound concept and management, see D7710; for the zygoma's anatomy, the fracture effects, and the open-reduction technique, see D7650. Maxillofacial trauma typically involves medical insurance. Documentation supports the claim.

When it's typically used

D7750 is reported for treating a malar (cheekbone/zygoma) and/or zygomatic arch fracture that is compound/open (the broken bone exposed to the mouth or outside) by open reduction — a surgical incision to access and realign the fractured cheekbone (and fix it as needed). It parallels D7650 but is in the compound-fracture series.

How much does D7750 cost?

Open reduction of a compound zygomatic/cheekbone fracture is significant surgery — often roughly 500 to 4,000+ USD for the procedure (fee schedules vary; some list around 500 USD), plus hospital/anesthesia, overall trauma care, and the management of the open/contaminated fracture (debridement, antibiotics). Medical insurance typically applies (maxillofacial trauma is a medical matter). Verify coverage with the medical insurer.

Is D7750 covered by insurance?

Maxillofacial fracture treatment typically involves medical insurance (trauma is a medical matter). Documentation of the fracture (the compound/open malar/zygomatic arch fracture — noting the bone exposure and effects, e.g., deformity, orbital involvement, trismus) and the open reduction (the surgical incision, reduction, fixation, and open-fracture management) supports the claim. It's distinguished from the closed reduction (D7760) and from the simple-fracture codes (D7650/D7660). Coordination with the medical insurer applies. Verifying coverage helps.

When a zygomatic fracture is compound

A zygomatic fracture can be open/compound, and understanding when clarifies the code.

Understanding when a zygomatic (cheekbone) fracture is compound/open clarifies D7750. A fracture is compound (open) when the broken bone communicates with the outside (the mouth or skin). For the zygoma (which forms the cheek prominence, part of the eye socket, and the zygomatic arch), this can happen in several ways: communication with the maxillary sinus — the zygoma connects to the maxilla and is near the maxillary sinus; a zygomaticomaxillary complex fracture can involve the sinus, and since the sinus communicates with the nasal/respiratory tract (and effectively the outside), such involvement can render the fracture open/compound; communication with the mouth — if the fracture extends to or through areas communicating with the oral cavity (e.g., the upper buccal region); and an associated wound — if there's a soft tissue wound (e.g., a facial laceration) exposing the fractured bone to the outside.

So a zygomatic fracture is compound when the bone is exposed/communicating with the mouth, sinus, or outside. This is the more serious, contamination-prone situation — needing the open-fracture management (cleaning, antibiotics) alongside the reduction. (A zygomatic fracture without such communication/exposure would be simple — coded D7650/D7660.) Understanding this helps patients see that a zygomatic (cheekbone) fracture can be compound/open when the broken bone communicates with the outside — e.g., through involvement of the maxillary sinus (which communicates with the respiratory tract/outside, as in a zygomaticomaxillary complex fracture involving the sinus), through extension to areas communicating with the mouth, or through an associated soft tissue wound exposing the bone — making it the more serious, contamination-prone situation that needs open-fracture management (cleaning, antibiotics) alongside the reduction, whereas a zygomatic fracture without such communication/exposure would be simple (coded D7650/D7660).

Open reduction of the compound cheekbone fracture

The open reduction surgically realigns the cheekbone, and understanding this clarifies the procedure.

The open reduction in D7750 surgically realigns the compound cheekbone fracture — the same open-reduction technique as D7650, with the open-fracture management. It involves: managing the open fracture — cleaning/debriding the contaminated site, antibiotics, and soft tissue management; surgical access — incision(s) to access the fracture site(s); the zygoma connects to other bones at several points (buttresses), so approaches may include intraoral (upper buccal vestibule), and small incisions near the eye (lower eyelid/infraorbital, lateral eyebrow); reduction — realigning the displaced zygoma back into its correct position (restoring the cheek prominence); fixation — fixing the reduced fracture as needed with plates and screws at the fracture sites (buttresses) for stability; and closure/ongoing care — closing, monitoring for infection, with follow-up.

The goal is to restore the cheek contour, the orbit (if involved — eye position/function), and jaw opening (if a depressed arch impinged), with a stable result — while managing the open/contaminated aspect. If the maxillary sinus is involved, that's addressed as part of the care. So the open reduction surgically realigns and fixes the compound cheekbone fracture while managing the open nature. Understanding this helps patients see that the open reduction in D7750 surgically realigns the compound cheekbone fracture (the same technique as D7650, plus the open-fracture management) — managing the open fracture (cleaning/debriding, antibiotics, soft tissue management), making incision(s) to access the fracture site(s) (intraoral, near the lower eyelid, or the lateral eyebrow), realigning the displaced zygoma to its correct position, fixing it as needed (plates and screws at the fracture sites/buttresses), and providing closure and ongoing care — aiming to restore the cheek contour, the orbit, and jaw opening with a stable result, while managing the open/contaminated aspect (including the maxillary sinus if involved).

Effects and goals (shared with D7650)

The fracture effects and treatment goals are shared with the simple version, and understanding this clarifies the purpose.

The effects of a zygomatic fracture and the goals of treatment are the same as for the simple version (D7650) — the difference being the open/compound nature. The effects of a displaced zygomatic fracture include: facial deformity — a flattened/depressed cheek or asymmetry (a cosmetic concern); orbital effects — since the zygoma forms part of the eye socket, changes in eye position, double vision, or numbness of the cheek/upper lip (the infraorbital nerve); and limited jaw opening (trismus) — if a displaced zygomatic arch impinges on the mandible's coronoid process. So the displaced fracture can affect appearance, the eye, and jaw function.

The treatment goals (via the open reduction) are correspondingly: restoring the cheek contour (correcting the deformity), restoring the orbit (eye position/function), and restoring jaw opening (relieving the impingement) — plus, for the compound fracture, preventing infection. So D7750 aims to achieve these goals for a compound zygomatic fracture. For the full detail on the zygoma's anatomy and the fracture effects, see D7650 (the simple version). Understanding this helps patients see that the effects of a zygomatic fracture and the treatment goals are shared with the simple version (D7650) — the effects of a displaced fracture being facial deformity (a flattened/depressed cheek or asymmetry), orbital effects (changes in eye position, double vision, or numbness of the cheek/upper lip), and limited jaw opening (trismus, from a displaced arch impinging on the coronoid process) — with the treatment goals (via the open reduction) being to restore the cheek contour, the orbit, and jaw opening, plus (for the compound fracture) preventing infection — so D7750 aims to achieve these goals for a compound zygomatic fracture (with the full anatomy and effects detailed under D7650).

Where D7750 fits in the codes

D7750 is the compound-cheekbone open reduction, and understanding this clarifies the coding.

D7750 fits in the systematic structure: the series — compound (open) fractures (D7710-D7780); the bone — malar/zygomatic arch; and the approach — open reduction. So D7750 = compound series, cheekbone, open reduction. Its neighbors: D7760 (compound cheekbone, closed reduction — the closed counterpart), D7650 (simple cheekbone, open reduction — the simple-fracture counterpart of the same approach), and the other compound codes (maxilla D7710/D7720, mandible D7730/D7740, alveolus D7770/D7771, complicated D7780).

So the surgeon codes a zygomatic fracture by: simple or compound? — choosing the series; and open or closed reduction? — within the series. For a compound zygomatic fracture treated by open reduction, D7750 is the code. Understanding this helps patients see that D7750 is the compound-series, malar/zygomatic arch, open reduction code — fitting the systematic structure — with neighbors D7760 (compound cheekbone, closed reduction), D7650 (simple cheekbone, open reduction), and the other compound codes (maxilla D7710/D7720, mandible D7730/D7740, alveolus D7770/D7771, complicated D7780) — so the surgeon codes a zygomatic fracture by whether it's simple or compound and open or closed reduction, selecting D7750 for a compound zygomatic fracture treated by open reduction.

Frequently asked questions

What is the D7750 dental code?
It's the open reduction of a malar and/or zygomatic arch fracture in the compound (open) fracture series — surgically treating a fractured cheekbone (malar/zygoma) and/or zygomatic arch, where the fracture is compound/open (the broken bone exposed to the mouth or outside), by making an incision to access and realign it (with fixation as needed). It parallels D7650 but is for an open/exposed fracture.
When is a cheekbone fracture compound/open?
When the broken bone communicates with the outside — e.g., through involvement of the maxillary sinus (which communicates with the respiratory tract/outside), extension to areas communicating with the mouth, or an associated soft tissue wound exposing the bone. A zygomatic fracture without such communication/exposure would be simple (D7650/D7660).
How is it different from D7650?
Both are open reductions of a cheekbone fracture (surgical incision, realignment, fixation), but D7750 is for a compound (open/exposed) fracture while D7650 is for a simple (non-exposed) one. The compound version (D7750) also involves managing the open fracture (cleaning, antibiotics, soft tissue care, the sinus if involved).
What problems does the fracture cause?
A displaced cheekbone fracture can cause facial deformity (a flattened/depressed cheek or asymmetry), orbital effects (changes in eye position, double vision, or numbness of the cheek/upper lip), and limited jaw opening (trismus, if a displaced arch impinges on the jaw). The treatment aims to restore the cheek contour, the orbit, and jaw opening.
What does the treatment involve?
Managing the open fracture (cleaning/debriding, antibiotics, soft tissue care) plus the open reduction (incision(s) to access the fracture, realigning the displaced cheekbone, fixing it with plates/screws at the buttresses), and ongoing care (monitoring for infection, follow-up). It aims to restore the cheek contour, orbit, and jaw opening with a stable result.
How much does it cost, and what insurance applies?
It's significant surgery — often roughly 500 to 4,000+ USD for the procedure (fee schedules vary), plus hospital/anesthesia, overall trauma care, and management of the open fracture. Medical insurance typically applies (maxillofacial trauma is a medical matter). Verify coverage with the medical insurer.
