After review of current billing requirements related to CPT® code 82542 (Column chromatography/mass spectrometry (eg, GC/MS, or HPLC/MS), analyte not elsewhere specified; quantitative, single stationary and mobile phase), it was determined that beginning with claims processed on or after November 13, 2014, providers billing more than one on a single detail line (same date of service) are able to be reimbursed for up to three units of service and should be indicated in the number billed (NB) field. Additional services over the initial three for the same date of service will be denied and must be appealed with supporting documentation.
