Welcome to the Physician Portal for National Biological’s Digital Timer (DT) Controller and Controlled Prescription Timer® (CPT) . Our CPT and DT ensure that phototherapy treatments are safely managed under physician supervision, promoting regular progress reviews between patients and healthcare professionals.

The DT and CPT render the device inoperable after a predetermined number of treatments, requiring a Refill Code from a healthcare provider to resume functionality.
