WebPT billing services for PT, OT and SLP practices

What is WebPT and who bills out of it?

WebPT is a software company in Phoenix, Arizona, that builds an electronic medical record and billing platform for rehab therapy. Its site names physical therapy, occupational therapy, speech-language pathology, behavioral health and chiropractic among the practices it serves.

Its billing pages show three paths: WebPT Billing for medium and enterprise practices, Therabill for small practices, and WebPT RCM, a full-service option where the vendor's own team bills for you.

The vendor's own FAQ says many clinics use third-party billers and that its tools work with internal or external teams. That is the setup this page covers: your clinic keeps WebPT, and we work the revenue cycle inside it. WebPT also sells its own RCM service.

How does an outside billing team get into your WebPT account?

We work inside accounts you create and control.

Which therapy modifiers must be on a WebPT claim?

Every Medicare outpatient therapy line needs the modifier for its discipline, per Claims Processing Manual chapter 5, section 20.1. WebPT says its billing has built-in rehab-specific modifiers.

CMS requires CQ and CO from January 1, 2020, and pays services carrying them at 85 percent of the fee schedule amount from January 1, 2022. We check the rendering clinician on each line against the modifier before a claim leaves.

What is the KX threshold for 2026, and what happens without the modifier?

For calendar year 2026 CMS sets the KX modifier threshold at $2,480 for physical therapy and speech-language pathology combined, and a separate $2,480 for occupational therapy. CMS states that claims for services over the threshold without the KX modifier are denied.

KX is the provider's confirmation that the services are medically necessary and documented. CMS warns that routine KX use on claims far below the threshold can draw scrutiny.

In WebPT we track each Medicare patient's yearly running total and add KX only past the threshold, where the note supports skilled care. CMS indexes the figure each year, so we use the amount on the CMS therapy services page for the year of service.

How many units can you bill under the 8-minute rule?

A single timed code reaches one unit at 8 minutes of direct, one-on-one treatment, and each further unit needs about 15 more minutes. The Medicare Claims Processing Manual, chapter 5, section 20.2 lists the bands, and the 8-minute rule governs how minutes turn into timed code units.

When several timed codes are delivered on the same day, CMS says the total timed minutes decide the number of units, and the units billed cannot exceed what those total minutes allow. Only time spent directly treating the patient counts, not waiting or rest breaks.

Example with made-up numbers: 20 plus 18 minutes of two timed services is 38 minutes, so 3 units. We check the unit count on each WebPT charge against the documented minutes before the claim is built.

What plan of care certification does Medicare expect before you bill?

Medicare covers outpatient therapy under a plan of care that a physician or non-physician practitioner has certified. Medicare Benefit Policy Manual chapter 15, section 220.1.3, says certification needs a dated signature on the plan or on another document approving it. The rows below come from that section, and the last row from Claims Processing Manual chapter 5, section 20.1.

CMS says to keep the certification in the clinical record. We match the first date of service, the certification date and the recertification date in the WebPT chart before we release claims and send missing signatures back to your clinic.

How do claims move from WebPT to the payer, and how are payments posted?

Professional therapy claims go out on the CMS-1500 form or its electronic version, the 837P. WebPT's billing pages say clearinghouse functions, including electronic workers' compensation and auto claims, are included in the subscription.

Hospitals, skilled nursing facilities and home health agencies bill outpatient therapy on the institutional claim, the UB-04 or its electronic form, the 837I. The vendor lists Medicare Part A institutional billing as a capability of WebPT Billing for medium and enterprise practices.

On the payment side, the vendor describes automated posting, editable 835 files and rejection alerts. An ERA is the electronic remittance advice, X12 835 format. We post from it, then work any line carrying a CARC or RARC that signals a denial or reduction. See denial management for that follow-up.

What do we do in WebPT each day?

We follow each visit from charge to cash in the queues you assign.

• Charge review: discipline modifier, CQ or CO, units against minutes and diagnosis pointers.
• Claim edits: automated eligibility checks and multiple claim scrubbing rules, then claims held by the platform or clearinghouse are cleared.
• Submission: claims go out through your clearinghouse within 24 hours of charge entry.
• Posting: payments and adjustments from the 835, with short pays flagged.
• Denial work: denials are worked within 48 hours, with appeals built from the remittance codes.
• A/R follow-up and patient statements: unpaid payer balances by age, then patient balances after insurance.

Which reports do we pull for a therapy practice?

We describe reports by purpose, because the names and filters depend on your WebPT product and build. The vendor lists built-in reports and claim-level status tracking, and scope and reporting are agreed at setup.

These measures feed our revenue cycle management service.

How we handle billing in WebPT

We run billing inside your WebPT setup through named accounts, your clearinghouse and your payer portals, and we report from your own data. We claim no partnership with the vendor. The rules behind this work are on our physical therapy billing page; see also CentralReach, the EHR hub and security.
