Hear what our clients have to say about ZMark

We would like to share some commentary on the delivery of your company’s credentialing service. Since taking over the credentialing in late 2020 and successfully winning the RFP in February 2021, EHN has seen a sharp decline in problems relating to credentialing, including a reduction in claims denials associated with practitioner enrollment.

The ZMark team is attentive, responsive, and knowledgeable. We rely on your expertise to ensure our practitioners are enrolled properly with all Texas payers.
