Bimax Cost: What the Price Actually Covers

Bimaxillary osteotomy, commonly called bimax surgery, is one of the most structurally significant operations in facial surgery. It repositions both the upper jaw (maxilla) and lower jaw (mandible) at once, changing the way your teeth, airway and facial profile relate to each other. It is expensive, and the price on the quote is only part of what it costs.

This guide breaks down the financial cost, explains what drives the variation, and covers the cost that no quote prices in: the risk.

What Is Bimax Surgery?

Bimax surgery is a type of orthognathic (jaw-correcting) surgery. A surgeon cuts both jaws, repositions them, and fixes them in their new position with titanium plates and screws. The goal is to correct a skeletal problem, meaning the jaws do not fit together or function the way they should.

It is meant for:

• Skeletal Class III malocclusion (an underbite caused by jaw structure, not just teeth)
• Skeletal Class II malocclusion (a significant overbite with jaw involvement)
• Open bite, where the front teeth do not meet when the back teeth are closed
• Obstructive sleep apnea, in cases where moving the jaws forward may open the airway
• Facial asymmetry caused by uneven jaw development

It is not a cosmetic procedure, and insurers treat it accordingly. Because bimax involves two bone cuts rather than one, it is more complex, has a longer recovery, and costs more than single-jaw surgery.

The Cost That Isn’t on the Quote: Risk

Before any number below, this is what bimax can cost you that money does not cover:

• Lasting numbness. The cut in the lower jaw puts the nerve to the lower lip and chin at risk, and moving the upper jaw can affect the cheeks and upper lip. Most people regain much of that feeling over months. A minority do not.
• Relapse. The bones can drift partway back, especially after large movements, bringing back part of the original problem.
• Further treatment. More orthodontic work is common afterwards. Some people need another operation, for the bite or to remove hardware.
• Jaw joint problems. New clicking, pain or stiffness in the jaw joint can appear after surgery.
• Months of recovery. Weeks on a liquid or soft diet, months of swelling, and years of orthodontic treatment around the operation.

The full list, and what each risk means in practice, is in our bimax before and after guide.

The Average Bimax Cost

In most Western countries, the all-in cost for bimax surgery ranges from roughly $20,000 to $50,000 USD when paid entirely out of pocket. In the United States, quotes often land between $25,000 and $40,000 for a reputable surgeon at an accredited facility. In the United Kingdom, private costs typically run from £15,000 to £30,000.

Medical tourism destinations such as Thailand, South Korea, Turkey and Mexico list bimax at lower prices, sometimes between $8,000 and $18,000 all-inclusive. A lower price does not automatically mean lower quality, but it does mean more risk on your side if something goes wrong once you are home.

These are estimates. Your actual quote will depend on the factors below.

What Drives the Cost?

Bimax cost is not a single number. It is a sum of several components, and surgeons may quote differently depending on what they bundle together.

Surgeon Fees

The surgeon’s fee is usually the largest single line item, typically ranging from $8,000 to $20,000+ in the US. Surgeons who specialize in orthognathic and craniofacial work, or who practice at academic medical centers, tend to charge more. Experience matters: a surgeon who has performed hundreds of bimaxillary procedures tends to have a lower complication rate.

Anesthesia

Bimax is performed under general anesthesia. The anesthesiologist charges separately in most cases, usually $1,500 to $4,000 depending on the length of the procedure. Bimax typically takes three to five hours in the operating room.

Hospital or Surgical Facility Fees

You will usually spend one to two nights in the hospital afterwards. Facility fees cover the operating room, nursing care, recovery room and inpatient stay. These range from $5,000 to $15,000 in the US.

Pre-Surgical Orthodontics

Most bimax patients need orthodontic treatment before surgery to align the teeth within each arch before the jaws are moved. This can add $4,000 to $8,000 if you do not already have braces or aligners, and it extends the timeline by one to two years in many cases. Orthodontic finishing after surgery is also required.

Imaging and Diagnostics

Your surgeon will need cone beam CT (CBCT) scans, cephalometric X-rays, dental models and sometimes 3D surgical planning. These pre-operative diagnostics typically cost $500 to $2,000.

Surgical Splints and Hardware

Titanium plates, screws and any occlusal splints (bite guides used during surgery) are often billed separately. Expect $500 to $2,000 for hardware.

Post-Operative Care

Follow-up visits, prescription medications and possible physical therapy for jaw mobility are additional costs. Budget $500 to $1,500 for post-op care.

Insurance Coverage for Bimax

Whether insurance covers bimax surgery depends on the indication and your policy.

When insurance may cover it:

• Documented skeletal malocclusion with functional impairment (difficulty chewing, speaking or swallowing)
• Severe obstructive sleep apnea where jaw advancement is medically indicated
• Cases where conservative treatments have failed and the condition is causing measurable harm

When insurance typically will not cover it:

• Aesthetic improvement as the primary goal
• Cases where the insurer classifies the procedure as elective

If functional indications exist, your oral surgeon will need to document the medical necessity in detail. Prior authorization is required by most insurers. Even with insurance, you may still owe a meaningful portion through deductibles and co-insurance.

Geographic Price Variation

Where you have surgery has a large impact on the price.

Region	Estimated Out-of-Pocket Cost
United States	$25,000 to $40,000
United Kingdom (private)	£15,000 to £30,000
Western Europe	€18,000 to €35,000
South Korea	$10,000 to $20,000
Thailand	$8,000 to $15,000
Turkey	$7,000 to $14,000
Mexico	$8,000 to $16,000

These figures are approximations.

If you are looking at surgery abroad, factor in flights, accommodation for yourself and a companion, follow-up care back home, and what happens if a complication needs treatment after you have flown back. Problems are harder and more expensive to deal with far from the surgeon who operated.

Hidden Costs People Often Overlook

Several costs catch patients off guard:

1. Pre-surgical orthodontic treatment (often not included in the surgeon’s quote)
2. Post-surgical orthodontic finishing (typically six to twelve months)
3. 3D surgical planning fees (some practices charge separately)
4. Lost income during recovery (liquid diet and restricted activity for four to six weeks)
5. Travel costs for multiple pre-op and post-op appointments
6. Revision surgery or hardware removal, which is not rare enough to ignore and is expensive
7. Additional procedures such as genioplasty, which some patients add and which bring their own risks

Always ask for an itemized estimate, not just a total.

Is It Worth It?

For a genuine functional problem, such as a bite that makes chewing difficult or jaw position that restricts breathing, bimax can be worth both the money and the risk. That is a decision to make with surgeons who have examined you.

For appearance alone, our answer is no. The permanent risks are hard to justify when the jaw works fine, and the changes people want from the surgery often come partly from things that carry no surgical risk: lower body fat, better posture, a beard or haircut that suits the face shape. Those are slower and less dramatic, and they are reversible.

If a Doctor Has Recommended Bimax for a Functional Reason

• Get at least two, ideally three, consultations. Ask each surgeon what movements they would make and why, and whether a smaller procedure or orthodontics alone could solve the problem.
• Ask for the surgeon’s own complication rates. Specifically nerve injury, relapse, and how often hardware has to come out.
• Ask about volume. A surgeon doing bimax regularly, say twenty or more per year, will typically have better outcomes than one doing it occasionally.
• Use an HSA or FSA if available. Medically indicated orthognathic surgery typically qualifies.
• Check academic medical centers. Teaching hospitals affiliated with dental schools sometimes offer lower rates, with attending surgeons supervising residents.
• Get the full orthodontic plan in writing, including both phases before and after surgery.
• Request itemized quotes from every provider, including anesthesiologist and facility.
• Plan a contingency. Budget 10 to 15 percent above your quoted total for unexpected costs.

Summary

Bimax surgery commonly costs $20,000 to $50,000 in high-cost markets, driven by surgeon fees, facility costs, anesthesia, hardware and the orthodontic treatment around it. Insurance may cover a meaningful portion when functional problems are well documented. Medical tourism can lower the price but moves more of the risk onto you.

The bigger cost is not financial. Bimax carries risks that can be permanent, which is why it belongs to people with a real functional problem and qualified surgeons who have examined them, and not to anyone looking to change their appearance.
