I am completely lost here I would really appreciate someone's expertise as this is not my area of coding. I thought it was 21433 but I was wrong
TIA

POSTOPERATIVE DIAGNOSIS: Multiple facial fractures to include nose, left

orbital floor, bilateral LeFort lll.

PROCEDURES: Closed nasal reduction with stabilization, open reduction and

internal fixatjon of bilateral LeFort lll with intermaxillary fixation, and

open reduction and intemal fixation of left orbital floor fracture through

multiple approaches.

DESCRIPTION OF PROCEDURE: The patient was brought to the operative suite,

anesthesia induced without difficulty. The patient, procedure, and laterali$

confirmed. The face was prepped and draped. This being done, the left orbit

was evaluated 1st after local aneslhetic was injected. A subciliary incision

was made and extended laterally in the Crow's feet' A muscle skin tlap was

elevated, not perforating the orbital septum down to the orbital rim. At ttis

point, the periosleum was raised off the floor of the orbit and the fracture

as well as its margins identified' Dissection was then taken inferiorly

identifying the infra orbital nerve and dissecting around it until the facial

fractures in the maxilla were identified. Once this had been performed'

intaoral incisions were made bilaterally in the alveolar labial sulcus on

either side of the piriform aperture. These were taken immediately down to

the bone and the periosteum raised off the anterior maxilla bilaterally

identifying both medial and lateral buttress fractures. The entire mid face

appeared to be depressed and Rowe disimpaction forceps were inserted'

These were then pulled anteriorly and the face was displaced anteriorly. This

was done to the extent that I was able to get normal occlusion. Once this was

done, IMF screws were placed in the maxilla and mandible, so as not to

penetrate the apex of any viable teeth and these were wired together. Once

the patient was felt to be in good occlusion, L-plates were placed on tre

lateral butfesses bilaterally and L-plates were then placed on the medial

buttresses bilaterally. Each of them was bent, shaped accordingly, trimmed,

and 2 screws placed on either side of the fracture. The maxillary sinuses

bilaterally were inigated and washed out. Once this was performed, a piece

of the maxillary facture bone was removed because it was so comminuted. This

being done, the wound intraorally was closed in 2 layers and the surgeon's

gloves changed. At this point, attention to the left eye was performed. The

orbital plate was contoured appropriately for the defect and secured. At his

point, that wound was closed in 2 layers, suspending the orbicularis oculi

Iaterally and superiorly in he skin. Once this was performed, the nose was

evaluated. A Sayre elevator was placed intranasally and the nose fractured

into the midline. Stabilization plate was then placed over the skin of tre

nose. The IMF screws were hen removed after cutting he wires and IMF

removed intraoperatively.
 
What about 21435-50?

Did you get a denial, and were any other codes coded with you mentioned procedure code 21433?
 
When I code this out using CPT manual, 3M and Vitalware, I get (in order of RVU's with no CCI issues - appears would be a clean claim): 21387 -LT, 21345 and 21320
 
I reviewed 21435 and it doesn't seem to include the multiple approaches and doesn't seem to encompass all the work he did
You are correct, as there would be other codes you would use to bill with this code.

The other codes i was looking at are 21435-50, 21387, 21320
 
To clarify the modifier use for the coding I provided, refer to the National Fee Schedule RVU, the code 21435 is priced as bilateral so -50 would not be appropriate, 21387 would use Lt/Rt or 50, and 21320 does not allow use of laterality modifiers. Hope this helps!
