Why the phone matters for physical, occupational and speech therapy clinics

Therapy plans of care involve many visits over several weeks, so clinics spend a large share of phone time scheduling and confirming. Referral sources and payers also call to check on authorizations and progress.

Calls physical, occupational and speech therapy clinics commonly handle:

• A patient calls with a new referral after surgery.
• A patient calls to reschedule several visits around travel.
• A physician's office calls to send a referral.
• The clinic calls patients to fill a cancelled slot.
• A case manager calls about a workers' compensation patient.

Texting and after-hours calls

Reminder texts and quick reschedule replies help keep a full schedule full.

After-hours calls are usually scheduling requests or questions about the first visit.

Practices that handle protected health information should review their own privacy obligations before recording calls, enabling AI summaries or texting appointment details, and keep clinical conversations out of text messages unless their policies allow it.

Callata comes to $179.00 a month for 9 users ($99 a month with 5 users included, then $20 per additional user), below both.
