Beginning October 1, 2017, the Department will implement unit limits on presumptive drug test CPT codes 80305, 80306 and 80307. The unit limit is four (4) per month per client for each code. This unit limit applies to all provider types. Additionally, substance-specific confirmatory tests, CPT codes 80320 – 80377, must have a positive or inconclusive presumptive test for the specific substance(s) being tested within two (2) days prior to the test unless the test is performed in a hospital setting. The positive or inconclusive results of the presumptive test must be scanned and attached to the claim. Confirmatory tests without the corresponding positive or inconclusive presumptive test are not eligible for reimbursement.
