Which DLT template category fits each healthcare message?

TRAI DLT rules decide whether a message reaches DND numbers and at what time it can be sent.

MessageDLT template typeReaches DND numbers?Notes
Patient portal or app login OTPService Implicit (OTP)Yes, 24x7Triggered by the patient's own action
Appointment confirmation, reschedule or reminderService ImplicitYesPatient has an existing relationship with the provider
Lab report ready / discharge summary linkService ImplicitYesSend a secure link, never the diagnosis in the SMS text
Vaccination or follow-up reminder to registered patientsService ImplicitYesCovers parents of registered child patients
Health camp or check-up package offer to consenting patientsPromotional (-P, with recorded consent; formerly service explicit)Yes, with recorded explicit consentConsent captured on DLT or via your own verified opt-in

Every template, sender ID (header) and URL must be registered on DLT before sending. Avoid putting diagnosis or test results in the SMS body; share them through authenticated links.
