Today's post comes from Tom Ambury, PT and compliance officer at PT Compliance Group, based off this month’s “Compliance Chat” blog post.

Tom AmburyWe are now well into the exception process associated with the $3,700 threshold. The clinics that I’ve been working with have done fairly well in that they have not received any outright denials of services. But let's look at the responses we have received:

The responses from the Medicare Administrative Contractors (MACs) have fallen into three categories: Approval, Partial Approval, and Additional Documentation Requests (ADRs). Let's go through each one to see what Medicare will require of you.

  • Approval: Your request for 20 treatment days (or however many you requested) has been accepted. The only thing you need to do is count your visits to make sure you don't exceed the number of visits approved.
  • Partial Approval: You requested 20 treatment days, but Medicare granted you a lower amount. Again, the only thing you need to do is count your visits to make sure you don't exceed the number of visits granted.

Note that just because you’ve received approval for 20 visits maximum doesn’t mean you’re limited to those visits. The number of visits you can ultimately receive depends upon your ability to justify the medical necessity of the care you’re providing. So, as you treat, if your patient still needs care and you can justify the additional visits, you can reapply for another exception and request up to 20 additional visits.

  • Additional Documentation Requests: I have seen multiple additional documentation requests (ADRs), and you must make sure you handle these correctly. I’ve seen these due to the therapist not meeting the signature requirements and/or not justifying the procedures provided on a date of service. Be sure to read ADRs carefully to see specifically what Medicare has requested. (Note that all documentation completed through WebPT is automatically electronically signed.)
    • For signatures, download the signature attestation form from the MAC's website and fill it out. With this form, be sure to actually sign the required documentation; do not use a signature stamp. If your name and license number does not appear when you print the forms, legibly print your name and license number on the document(s). The supervising therapist must also co-sign all PTA notes.
    • For justifying procedures on a requested date of service, write an addendum to the note. You will want to include your clinical rationale, i.e., why you performed the procedure you’re justifying. Be specific, objective, and measurable. Remember, you are providing a specific treatment procedure to address a specific impairment identified at the patient's evaluation or reevaluation and for which you have an objective measure.

I am seeing requests to justify ESUN (Electrical Stimulation Unattended, G0283). ESUN is traditionally for pain reduction so Medicare would expect you to document pain, so be sure to include the pain rating scale and how the patient responded to the treatment. Again, in your addendum to your note you want to relate back to those objective measures. I would also include a statement regarding the patient's ability to function.

Is it true that I only need to send to the MAC what the ADR has requested? No.

Remember, this is Medicare. You must justify the date of service requested within the ADR, so in addition to the addendum to your note, send the following:

  • Prescription
  • Initial evaluation/reevaluation
  • Signed POC (Plan of Care) covering the visit(s) requested
  • Visit note(s) for the requested date of service(s)
  • Addendum explaining your clinical rationale and your justification of your treatment
  • Flow sheet covering the date of service
  • Signature attestation sheet
  • Anything else you think might be helpful in justifying the care you provided

The letters from MACs that I have seen give you 30 or 45 days to respond. The letter includes a fax number, so reference that, and when you fax the information to the MAC, include the initial letter you received.

Once you fax the required information to the MAC, the MAC then has ten business days to make a decision, right? Wrong.

The ten business days were for the initial preapproval exception only. Now that you have received an ADR, the MAC will handle it in traditional manner, i.e., as much time as they need to make a decision (generally 45 to 60 days, or even longer in some instances). With an ADR, the MAC is now trying to determine if the services you provided and are requesting to provide are reasonable and medically necessary. Consider having your documentation reviewed before submitting it to your MAC for their review.

Denials: I have not seen one, but I know they are out there. You have a choice of responses to the denial:

  • Acceptance: You accept the denial of the services you requested and thus you are not required to take any further action.
  • Appeal: If you receive a denial, but you feel the services you provided are reasonable and necessary, you can appeal. (Note that you cannot initiate the appeal until you first submit a claim and the MAC denies that claim.) If you appeal, though, be aware that the argument will center on what you have documented in that record. If you want to appeal, check the record and make sure it supports the services provided. The more objective, measurable, and therefore, defensible your documentation is, the better chance you have at appealing the denial.

This is a weighty topic, I know, so if you have any questions or comments, please post them in the comments section below. You can also contact the PT Compliance group at or 888-680-7688.

    Common Questions from our Modifier Open Forum

    Should I have my patients sign an advance beneficiary notice of noncoverage (ABN) just in case Medicare doesn’t pay? No, by having your patient sign an ABN, you are acknowledging that you do not believe that the services you are providing are either medically necessary or covered by Medicare. If you have an ABN on file, you should include a modifier GA or GX modifier on your claim so Medicare knows to deny the claim and assign …

    Medicare and Cash-Pay PT Services, Part 2: Covered vs. Non-Covered Services and Therapy Cap Essentials

    In the first article of this series on Medicare and Cash-Pay PT Services, we defined the three relationships a PT can have with Medicare and explained how each one influences the types of services (i.e., “covered” and “non-covered”) we can provide to beneficiaries on a self-pay basis. So, now we need to define which services are covered and which are not covered, as well as pinpoint the scenarios in which covered services may become non-covered. 3 Scenarios …

    Direct Access: What are the Risks?

    All states have amended their PT practice acts to allow for providing some form of PT services under direct access—or, put more simply, treating without a physician referral. But with this right comes added risks. It’s important to understand some of the potential risks and, hopefully, avoid them as much as possible. With that in mind, here are some main points to consider. 1.) Each state has its own rules governing direct access; therefore, it’s important to …

    The Legality of Performance-Based Employee Incentive Programs in Rehab Therapy Practices

    The concept of pay-for-performance (PFP)—that is, the idea that an individual receives payment based on what he or she produces—seems very American to me and is certainly part of our capitalistic society. To use a sports analogy, a professional athlete who is one of the top performers in his or her sport commands higher compensation than an average or poor performer. So, why would therapy practice owners, directors, and executives not consider offering salary/compensation rates based on …
