Maxillofacial Prosthetic Codes (D5900–D5999)
The D5900 range is the least familiar part of the code set and the most specialised. It covers prostheses that replace parts of the face and mouth lost to cancer surgery, trauma or congenital difference: obturators that close a hole between mouth and nose, prosthetic eyes, ears and noses, appliances that position a patient precisely for radiotherapy, and feeding aids for infants born with a cleft.
Almost nobody arrives at these codes by browsing. People arrive because a maxillofacial prosthodontist is part of their treatment team after a diagnosis, and the question they need answered is usually not clinical but administrative: who pays for this. That is what this page concentrates on.
What is in the range
Facial and ocular prostheses (D5911–D5928). Prosthetic eyes, ears, noses, and larger facial sections, made from medical-grade silicone individually coloured to match the patient's skin. Held by adhesive, by spectacles, or by implants placed in the surrounding bone.
Obturators (D5931–D5936). Appliances that close a defect between the mouth and the nasal cavity or sinus after surgery to remove part of the palate. Without one, speech is hypernasal and fluids pass into the nose. There are three stages: a surgical obturator fitted in theatre, an interim one during healing, and a definitive one months later.
Resection and speech prostheses (D5951–D5960). Appliances for patients who have lost part of the jaw or soft palate, including palatal lifts and speech aids designed with a speech and language therapist.
Radiation devices (D5983–D5988). Carriers that hold a radioactive source in position, shields that protect healthy tissue, and stents that hold the tongue or jaw in an exact position for each fraction of radiotherapy so that the treatment field is reproducible.
Other appliances (D5982–D5999). Surgical stents, feeding aids, trismus appliances to maintain opening after radiation fibrosis, and nasal stents.
Why this is usually a medical claim, not a dental one
This is the practical crux of the range. These prostheses are almost always a consequence of a medical condition — a malignancy, an accident, a congenital defect — and most medical insurers cover prosthetic replacement of body parts lost to disease or trauma. What that means in practice: the claim goes to the medical plan first, with the dental plan coordinating as secondary. A claim filed only to a dental plan will usually hit the annual maximum, which at $1,500 will not touch a $12,000 facial prosthesis. Three things make that claim work. A diagnosis code from the treating physician or oncologist, not just a dental narrative. A letter of medical necessity explaining the functional consequence — speech, swallowing, eye protection — rather than the appearance. And pre-authorisation obtained before the work starts, because retrospective approval in this area is rare. Hospital-based maxillofacial units generally have staff who do this daily. Where treatment is being provided outside that setting, ask explicitly who is handling the medical claim.
What to expect from a facial prosthesis
A silicone facial prosthesis is made in stages over several appointments: an impression or scan of the defect, a sculpted wax pattern fitted and adjusted for shape and symmetry, then a silicone casting individually pigmented — often in natural light, with the patient present — to match surrounding skin, including veins and freckles. The results can be remarkable at conversational distance. The honest limitations are that silicone does not move with the face, it does not change colour in the sun as skin does, and it degrades: two to three years is a typical service life before a remake, sooner for pieces exposed to sunlight. Implant retention, where the bone allows it, changes the daily experience substantially. Adhesive-retained prostheses require careful placement each morning and cleaning each night; implant-retained ones click on and off.
The obturator sequence, and why it is staged
A patient having part of the palate removed leaves theatre with a surgical obturator already in place, made from a pre-operative impression. Without it, swallowing and speech immediately after surgery are extremely difficult. Over the following weeks the wound contracts and reshapes, so the appliance is adjusted repeatedly or replaced with an interim obturator. Only when the tissue has stabilised — three to six months, longer if radiotherapy is involved — is a definitive obturator made. Each of those three stages is a separate code and a separate fee, and the sequence is planned from the start rather than being a series of failures. Anyone being quoted for this work should ask for all three stages costed together.

Maxillofacial prosthetics questions
Who pays for a facial or ocular prosthesis?
Usually the medical plan rather than the dental one, as prosthetic replacement of a body part lost to disease or trauma. File to medical first with a diagnosis code and a letter of medical necessity; a dental annual maximum will not cover it.
What is an obturator?
An appliance that closes a hole between the mouth and the nasal cavity or sinus, usually after surgery to remove part of the palate. It restores speech and prevents food and fluid passing into the nose.
How long does a facial prosthesis last?
Typically two to three years before a remake. Silicone degrades, pigments fade with sunlight, and the surrounding tissue changes shape over time.
Can a facial prosthesis be held by implants?
Where there is enough bone, yes — craniofacial implants let the prosthesis click into place instead of being held by adhesive. It is a substantial improvement in daily use and in retention during activity.
Why are there three separate obturator codes?
Because the appliance is made three times: a surgical obturator fitted in theatre, an interim one while the wound heals and reshapes, and a definitive one once the tissue has stabilised months later.
