Hi Christy!

No problem I'm happy to help :)

So first off, for the diagnosis coding. You'll want a code to represent the trauma to the teeth, and a code to represent the accident.

For example, some diagnosis coding options for the trauma to the teeth are:
K03.81 - Cracked tooth
S02.5XXA - Fracture of tooth (traumatic), initial encounter for closed fracture
S02.5XXB - Fracture of tooth (traumatic), initial encounter for open fracture
K08.411 - Partial loss of teeth due to trauma, class I
K08.412 - Partial loss of teeth due to trauma, class II
K08.413 - Partial loss of teeth due to trauma, class III
K08.414 - Partial loss of teeth due to trauma, class IV
K08.419 - Partial loss of teeth due to trauma, unspecified class


Now, for the accident, here are some coding options for you based on what you described:
V53.5XXA - Driver of pick-up truck or van injured in collision with car, pick-up truck or van in traffic accident, initial encounter
V53.5XXD - Driver of pick-up truck or van injured in collision with car, pick-up truck or van in traffic accident, subsequent encounter


As for the crown:
D2750 - crown - porcelain fused to high noble metal

The code listed above does not have a direct crosscode we are aware of, so you can either bill the "D" code on the medical claim (many insurers these days will process "D" codes when they are medically necessary services), or you can try the CPT code below and include a narrative report describing the procedure:
41899 - Unlisted procedure, dentoalveolar structures


As for the x-rays:

It depends on what all x-rays you took, but here are some x-ray CPT coding options:
70355 - Orthopantogram (eg, panoramic x-ray)
70350 - Cephalogram, orthodontic
70250 - x-ray lateral skull
70486 - Computed tomography, maxillofacial area; without contrast material.


Hope this helps!
