When it comes to reporting cytogenetic studies, is it ok to bill the 8XX99 codes for unlisted procedures?


Avoid using the 8XX99 codes for unlisted procedures. Refer to Methodology or Category III before selecting an unlisted code. Although many labs use them as a “miscellaneous lab” code, Medicare as a general rule does not reimburse unlisted codes without a special report. Unlisted codes should be used sparingly.
