Wiki Sural Nerve Biopsy

Does anyone know the CPT code that best describes a "sural nerve biopsy"? Thank you for your help in advance. :)

There is only code for nerve biopsy as 64795.
" The physician biopsies a nerve. The physician makes an incision overlying the suspect nerve. The tissue are dissected to locate the nerve, and a biopsy specimen is obtained. The incision is sutured in layers."
