Billing, Insurance Verification, and Revenue Cycle Basics

Why Billing Matters to a Rehab Aide

As a PT aide, you will not submit claims or negotiate with insurance companies — that is the job of the clinic's billing staff. However, you work inside the revenue cycle every day. Your documentation of the tasks you performed, the time spent, and the equipment used feeds directly into the billing process. Errors or omissions on your part can delay payment, trigger audits, or create compliance problems for the clinic. Understanding how the system works makes you a more accurate, careful team member and protects both patients and the practice.

The Revenue Cycle Step by Step

Step 1 — Insurance Verification. Before a patient's first appointment, the front office (or a dedicated verification specialist) contacts the patient's insurer to confirm active coverage. The verification form captures the plan name, group number, member ID, deductible amount and how much has been met, the number of PT visits allowed per year, and whether a referral or prior authorization is required. Missing or wrong information here can cause a claim to be denied later.

Step 2 — Referral and Prior Authorization. Some insurance plans require a physician referral before PT can begin, and some require the clinic to obtain prior authorization — a pre-approval number — for a set number of visits. The aide's role is to notify the supervising PT or front-office staff immediately if a patient mentions their plan requirements, and never to schedule or begin treatment that has not been cleared.

Step 3 — Charge Capture / Superbill. After each visit the supervising PT records the services provided on a superbill (also called an encounter form). A superbill lists the patient's diagnosis codes (ICD codes) and the procedure codes (CPT codes) for each service billed, along with units of time. The PT — not the aide — selects and signs off on these codes. Your accurate documentation of what tasks you performed, and for how long, supports what the PT records.

Step 4 — Claim Submission. The billing department submits a claim to the insurer, most often electronically. The claim includes patient demographics, insurance information, diagnosis codes, CPT codes, and the provider's credentials. Billing staff verify that codes are supported by the clinical documentation before submitting.

Step 5 — Remittance and Payment. The insurer processes the claim and sends back an Explanation of Benefits (EOB) or Electronic Remittance Advice (ERA). This document shows what was billed, what the insurer paid, what was adjusted or denied, and what the patient owes. Denied claims may be appealed or corrected and resubmitted.

CPT Codes Relevant to PT Aides

Current Procedural Terminology (CPT) codes are five-digit numbers maintained by the American Medical Association that describe medical procedures and services. In a PT clinic, aides assist with treatments that may be billed under certain CPT codes, but only the licensed PT or PTA who supervises and clinically directs the service selects and certifies the code. Examples of categories you will see in PT settings include:

• Therapeutic exercise — active or active-assisted exercises progressed by the PT/PTA
• Therapeutic activities — functional task training directed by the PT/PTA
• Manual therapy — hands-on techniques performed exclusively by the licensed clinician, never the aide
• Modalities (e.g., hot packs, electrical stimulation) — some are supervised modalities you may set up under direct supervision; others require constant skilled attendance by the licensed clinician

Aides must document only the tasks they actually performed. Documenting a task you did not do — or a time unit you did not work — is falsification of records and can constitute healthcare fraud. This is a serious legal and ethical violation that can end your career.

Insurance Verification: Your Practical Role

In smaller clinics, the aide may be asked to conduct an insurance verification call or to complete the verification form from information on the patient's insurance card. A correct verification call covers:

1. Patient's full legal name and date of birth

2. Insurance plan name, group number, and member ID

3. Policy effective date and any termination date

4. Deductible amount and year-to-date amount met

5. PT benefit: number of visits allowed per plan year and visits remaining

6. Copay or coinsurance per visit

7. Whether prior authorization is required (and if so, the authorization phone number or portal)

8. Name and ID number of the representative you spoke with, and the date and time of the call

If any field cannot be confirmed, write "unable to verify" — never fill in a guess. Fabricating insurance information is a compliance violation.

Scope of Practice and Safety

Documentation errors in billing can harm patients indirectly: an incorrect code may suggest a service was provided that was not, affecting the patient's medical record and future care decisions. Always ask the supervising PT or billing staff before completing any form you are unsure about. Your job in this system is accuracy and transparency — when in doubt, ask, do not assume.
