D7490 — Radical resection of maxilla or mandible
D7490 is radical resection of part of the upper or lower jaw, the major cancer-surgery code in this range.
eight codes describe cyst and tumour removal, and this is one of them. What separates it from the other seven is the subject of this page; the cyst and tumour removal guide covers the treatment itself.
The rest of this page deals with the specifics: the requirements written into the code, the usual range of fees, the typical benefit outcome, and how to tell it apart from its closest relatives.
What the code commits to
Bone — the upper jaw. Maxillary fractures usually follow a recognised pattern through the midface, and the priority is restoring the bite: the upper teeth have to meet the lower ones the way they did before. That is why these cases are managed jointly with the dental occlusion in mind rather than as isolated bone work.
Arch — upper. The palate provides broad support for anything removable, but the sinuses sit directly above the back teeth, which constrains surgical work.
D7490 against the codes beside it
D7509 — Marsupialization of odontogenic cyst: It marsupialises a cyst instead of removing it: the cyst is opened and left draining so that it shrinks before any definitive surgery.
D7461 — Removal of benign nonodontogenic cyst or tumor — greater than 1.25 cm: It removes a non-odontogenic benign cyst or tumour larger than 1.25 centimetres.
D7460 — Removal of benign nonodontogenic cyst or tumor — up to 1.25 cm: It removes a benign cyst or tumour up to 1.25 centimetres that did not arise from tooth-forming tissue.
D7451 — Removal of benign odontogenic cyst or tumor — greater than 1.25 cm: It removes a cyst or benign tumour of tooth-forming origin measuring more than 1.25 centimetres, which usually means removing bone with it.
D7490 sits in a group of eight codes in total; the remainder are linked at the foot of this page. Where the codes sit this close together, the record of the appointment is what settles which one was earned. That is worth knowing before treatment rather than after.
Every code in this group
These codes describe the same broad procedure and differ in one respect each. Each has its own page with its own fee range and coverage notes.
Questions about D7490
What is D7490 on my dental bill?
On a claim, D7490 tells the insurer that what was performed was radical resection of maxilla or mandible.
What should I expect to pay for D7490?
Most private fees fall in $5,000–$20,000. Geography accounts for more of that spread than anything clinical.
Will my plan pay for D7490?
Yes on most policies, treated as major oral surgery / medical work at variable. A waiting period on a new policy is the commonest reason it is not.
What is the difference between D7490 and D7509?
D7509 is marsupialization of odontogenic cyst: it marsupialises a cyst instead of removing it: the cyst is opened and left draining so that it shrinks before any definitive surgery. The two are neighbours by number rather than by treatment, so seeing both on a plan usually means both were genuinely planned.
Also known as: jaw cyst, odontogenic cyst, ameloblastoma, marsupialisation, jaw tumour.
