InvoiceFlow for Physical Therapists: The Complete Billing Guide

Billing for cash-pay sessions, superbills, prepaid packages, corporate wellness, and telehealth

Cash-pay physical therapists need billing that generates professional session invoices, produces superbills for out-of-network reimbursement, handles prepaid package tracking, and manages corporate employer wellness contracts. InvoiceFlow covers all of it from a single Android app.

Cash-Pay Session Invoices

Every cash-pay session should generate a professional invoice at checkout — both as a receipt for the patient and as the documentation foundation for a superbill.

Physical Therapy Session — [Patient Name] — [Date]:

Collect at checkout via the method shown on the invoice. No post-session collection.

Common PT CPT Codes

Note: CPT coding for PT involves timed codes billed in 15-minute units. Consult your state PT association or a healthcare billing specialist to confirm appropriate coding for your services and licensure.

Superbills for Out-of-Network Reimbursement

Rehab programs, home visits, corporate ergonomics — every revenue stream on one screen.

Every cash-pay patient should receive a superbill they can submit to their insurance for out-of-network reimbursement.

Superbill — [Patient Name] — [Date of Service]:

“This superbill is provided for patient insurance reimbursement purposes. It does not constitute a claim submission to any health insurance plan.”

Common ICD-10 Codes for PT

Generate the superbill at every checkout. Email it directly from InvoiceFlow. Patients submit to their plan; most commercial plans reimburse 40–70% of out-of-network PT costs.

Telehealth Superbills

For telehealth sessions, add:

Prepaid Session Package Invoices

Prepaid packages commit the patient to a protocol, improve completion rates, and collect revenue before services are rendered.

PT Session Package — [Patient Name] — [Enrollment Date]:

Package Tier Structure

Build a separate InvoiceFlow template for each package tier. At enrollment, enter patient name, select package — pricing auto-populates.

Corporate and Employer Wellness Invoices

Employer wellness PT contracts — on-site injury prevention, ergonomic assessments, early intervention sessions — run on purchase orders and net-30 terms.

Corporate Wellness Services — [Company Name] — [Month Year]:

Billing Period: [Month Year]

Remit to: [Name], DPT | EIN: [XX-XXXXXXX] PO Number: [PO-####] Payment Terms: Net-30 W-9 on file | Submitted: [Date]

EIN is required on all corporate invoices. Corporate AP cannot create a vendor record without it. Include EIN on the invoice and have W-9 on file before billing.
