Why Most PT Notes Get Denied (And How to Fix It)
I spent about twelve years in outpatient ortho before moving into clinical documentation consulting, and the number of notes I've seen rejected by insurance companies is honestly just ridiculous. You'd be surprised how many licensed therapists still think a note that reads "pt improved" is enough to justify another six weeks of treatment. It isn't. Not even close. The core issue isn't laziness. It's that most DPT programs teach you anatomy and biomechanics until you can recite them in your sleep, but they give you maybe two days on documentation, and that's usually a lecture on what an ICD-10 code looks like. You graduate knowing how to treat a rotator cuff tear and how to bill for it, but you have no idea how to write a note that will survive a peer review audit from a payer who doesn't know the difference between a hamstring strain and a lumbar radiculopathy.
By Mia Erickson Physical Therapy Documentation From Examination To Outcome 2nd Edition
Mia Erickson's book is one of the few resources that actually bridges that gap between what you learn in school and what gets you paid. The second edition updated a lot of the coding sections for the changes that came through over the past few years, which matters more than you might think. Medical necessity reviews are stricter now than they were even five years ago. If your documentation doesn't explicitly tie the impairment to the functional deficit and then tie that deficit to the intervention, the claim goes into the backlog and eventually gets denied on a technicality you could have prevented in three minutes of writing time. The book doesn't sugarcoat anything. It walks through the exam, the assessment, the plan, and the ongoing notes as a connected system. That's the part most people miss. You don't write a standalone initial eval and then separately write daily progress notes. They're the same document told across time, and if day 14 contradicts day 3, an auditor will spot it in twelve seconds. I've seen notes rejected because the therapist wrote that the patient had 90 degrees of knee flexion on the initial exam and then documented 120 degrees on a follow-up without explaining the methodological change or the intervention that produced it. That's not a coding problem. That's a logical inconsistency problem, and the book covers exactly how to avoid it. One thing the book gets right that I haven't seen in any other documentation guide is the emphasis on functional outcome measures. Too many therapists pick a scale because it's short and familiar, like the ODI or the lower extremity functional scale, but they never actually benchmark the patient against normative data or establish a minimal detectable change threshold before treatment starts. So when the payer asks "did this person actually improve by a clinically meaningful amount?" you can't answer it. You just know they feel better. Feeling better doesn't pay the bills. The book shows you how to set up measurable baselines during the exam that carry through to discharge, so your outcome data isn't just descriptive but defensible.
Here's a specific edge case I ran into that the book helped me work through. A client of mine was treating a post-operative ACL reconstruction patient. The surgeon's documentation was fragmented across three different EHR systems, and the PT notes needed to align with surgical parameters while also justifying home exercise program compliance issues. The insurance company wanted to know whether the patient was progressing appropriately or whether the timeline itself was atypical. I pulled the Erickson framework and mapped each intervention directly to a specific impairment-driven goal, tied that to a validated outcome measure with the MDC calculated, and then cross-referenced the timing against accepted post-op rehab guidelines. The claim was processed on the first submission instead of going to manual review. It took about twenty minutes longer per note but saved us from three weeks of delayed payment and a full peer record request that would have taken a day to assemble. There are some real limitations to be honest about. The book is written for general outpatient documentation patterns. Inpatient and acute care have different regulatory demands, and while the core principles transfer, you'll need supplemental guidance for Medicare inpatient criteria and therapy portion loads. The coding tables are useful but they do require you to keep them current on your own since CPT and ICD-10 updates happen annually. I print out the coding reference pages and keep them in a folder on my desk because I'm not about to memorize sixty pages of update changes. Another thing I'll say without fluff is that this book won't fix a broken EHR template. If your clinic's documentation system forces you into checkboxes that don't support narrative flow, you're going to fight the format every single note and the quality will suffer. The Erickson method works best when you have enough free-text space to explain the clinical reasoning. Some systems allow this. Most don't, and that's a clinic-level problem, not a documentation-problem. I've worked with therapists who bought the book, read it cover to cover, and still got denied because their facility requires templated notes that strip out the clinical justification language. No book can compensate for a system designed to produce shallow notes.

The counter-intuitive insight most people miss is that documentation quality is actually a treatment quality signal. When you write clear, impairment-based goals tied to measurable outcomes, you're forced to think more carefully about what you're actually doing with the patient. Vague notes correlate with vague treatment plans. The therapists I know who take documentation seriously tend to also have better patient outcomes because they can't bullshit their way through a case when they have to write it down in a way that survives external review. It's uncomfortable but it makes you sharper. If you're looking at getting the second edition, check the publication date against your state's current licensing and billing requirements. Some states have adopted specific documentation mandates that aren't reflected in older printing runs. The second edition is a solid improvement over the first, particularly around telehealth documentation rules that became necessary during and after the pandemic. Those sections alone are worth the price difference if you're seeing patients remotely, which most of us are doing at least occasionally now. The book is available through standard medical and therapy publishing channels. Physical Therapy Productivity has carried it for years, and the publisher's website lists the current edition directly. Compare the ISBN before ordering because there are multiple print runs and the 2nd edition has a distinct copyright page that you can verify against the listing.
What I usually tell people who ask me about this stuff is straightforward: if you're a new grad, read it before your third month on the job. If you've been practicing for ten years and your denials are climbing, read it and then audit your own notes against the framework for two weeks. You'll find inconsistencies you didn't know you were writing. The denials drop fast after that. I'm not saying it's glamorous. Documentation is tedious by nature. But it's the difference between getting paid and spending your evenings rewriting notes because a utilization reviewer decided your language was insufficient.
