The denial was for visit number thirteen. A woman recovering from a rotator cuff repair had been approved by her insurer for twelve visits, the therapist had written a strong progress note after the tenth, and nobody had sent it in. She came three more times. All three were denied, and the practice wrote off $486 on a patient who had done everything right.
It was not unusual. The practice is an outpatient physical therapy group with two clinics, one on Savannah Highway in West Ashley and one on Daniel Island: eleven physical therapists, four assistants, two people at each front desk, and about 1,900 visits a month -- post-surgical knees and shoulders, back pain, runners, a few high school pitchers every spring. Every one of those patients is working through a count someone else set. A commercial plan approves a block of visits and wants a progress note before it approves more.
Medicare wants a progress report at least every tenth visit and a plan of care the referring physician has signed, recertified before it lapses. Miss a count and the visits past it are not paid. When the owner finally added it up, the practice had lost $148,000 the year before to visits delivered past an authorization or a lapsed plan of care. The front desks tracked it on a whiteboard and a spreadsheet, between check-ins, phone calls and copays.
The therapists were seeing patients back to back. The counts slipped in the gaps between them. We delivered an AI Plan of Care Coordinator, built on ChatGPT Work under the practice's own account, and it keeps every count now. It wakes each time a therapist signs a visit note.
It knows what every patient's plan has authorized, how many visits are left, and when the physician's signature expires. Three visits before an authorization runs out, it pulls the therapist's most recent progress note and submits the request for more visits through that insurer's portal. Thirty days before a Medicare plan of care lapses, it sends the recertification to the referring physician's office for signature, and it follows up every third business day until the signature comes back. When a patient misses an appointment, it texts within fifteen minutes with two open slots at the same clinic and books whichever one they choose.
Seventy-one percent of missed visits are now rebooked the same week. The boundary is written at the top of its instructions and the therapists wrote most of it. It never writes, edits or signs anything clinical; the notes are the therapists' and only the therapists'. It never tells a patient that insurance will not pay for their care -- any denial goes to the billing lead the day it arrives.
It never discharges a patient and never changes a visit frequency. If a patient's balance passes $500, it stops booking and hands the account to the front desk. On the Friday before Labor Day, at 5:48 in the evening, one of the region's large commercial insurers emailed every provider a notice: starting Tuesday, requests for additional visits had to go in on a new form with a functional outcome score attached. Both clinics were closed through Monday.
It read the notice on Saturday morning, found the seventeen requests that were pending or due that week, rebuilt each one on the new form with the outcome score already in the therapist's last note, and resubmitted all seventeen by Sunday night. Three patients booked for Tuesday could not be approved in time; it moved each of them to Thursday and texted them why. The owner learned about all of it at 6:30 Tuesday morning, from a paragraph at the top of her inbox. That paragraph arrives every weekday at 6:30.
It lists what was submitted, what came back approved, which signatures are still out and how many days are left on each, and the one or two accounts that need a person. Most days, the last part is empty. The practice is on pace to write off under $20,000 this year for the same failures that cost it $148,000 the year before. The whiteboard is still on the wall behind the West Ashley front desk.
Nobody has written on it since June.
