The HCPCS code L8642 for a hallux implant was billed with 61510 (removal of cranial lesion), +61781 (intra-operative work of stereotactic navigation for intradural cranial procedure), and +69990 (use of operating microscope). Since these are all cranial procedures (and no other work was done to any other body part) I’m wondering why the hallux implant was billed? I thought L8642 was an ortho code that would be used in the repair and/or reconstruction of the big toe. Was a mistake made here? (perhaps a code for cranial surgical mesh/filling should have been used) or does ‘hallux’ refer to something else other than the big toe? I’m a little confused.

Thanks!
