Covered entity status
HRT and TRT clinics are covered entities under 45 CFR §160.103 the moment they transmit PHI electronically in connection with a covered transaction — primarily, electronic prescribing under NCPDP SCRIPT. For TRT specifically, testosterone is a Schedule III controlled substance, and electronic prescribing is regulated under both the standard HIPAA framework and the DEA's electronic prescribing of controlled substances (EPCS) requirements. The CE classification holds regardless of insurance billing, membership-fee structure, or wellness-clinic marketing.
