Are hospital labs that file institutional claims exempt from the MolDx Program requirements?

Part A providers billing for molecular services must register for a DEX Z-code identifier. Effective March 1, 2017, hospitals were required to add the DEZ Z-Code identifier in block 80 of the UB04 claim form or on line SV202-7 of the 8371 electronic claim. Providers submitting institutional claims are required to submit claims with DEX Z-Codes.
