Dental Blocks


Question

We have patients that come in for tooth pain and a dental block is done. Sometimes it is documented as aleveolar block and sometimes it is documented as infraorbital block. We are not sure what the correct CPT code would be. We were using 64400 but would this just be facial block 64402?

Answer

Dental blocks would be coded to 64400-Trigeminal nerve.  The maxillary nerve is a branch of the trigeminal nerve and includes the posterior superior alveolar nerve, middle superior alveolar nerve and anterior superior alveolar nerves.  These are the nerves that are focused when performing a dental block.  When these blocks are performed there may be some anesthesia effect on other nerves, mostly those of the chin and lip.
