How Maryland Certified Respiratory Therapist license verification works
A Certified Respiratory Therapist in Maryland is licensed by the MD Respiratory Care Board. PrimaryCheck looks the license up live at the board's public verification system (board lookup) by license number, or by name when no number is supplied. The record the board publishes is captured as evidence, hashed, and rendered into a proof PDF.
Fields returned for this board: name license_number license_type status issued expires disciplinary_md pending_charges.
Board note: Respiratory care practitioners are licensed by the Board of Physicians (prefix L); rrt and crt both map to 'Respiratory Care Practitioner'
