Common Questions and Answers
- Can a PTA treat a Medicare B patient in an outpatient setting with direct supervision by the physical therapist?
Answer: Yes, however PTAs are limited in the services they may provide. Please see CMS IOM Publication 100-02, Medicare Benefit Policy Manual, Chapter 15, Section 220. This section states, “PTAs may not provide evaluative or assessment services, make clinical judgments or decisions; develop, manage or furnish skilled maintenance program services; or take responsibility for the service. They act at the direction and under the supervision of the treating physical therapist and in accordance with state laws.
- Do I give the patient an ABN when they are approaching their cap?
Answer: You would only give the patient an ABN when you feel the continuation of services may be rejected by Medicare for medical necessity. If the patient is approaching the cap, but services will continue to be medically necessary for them you are to affix the KX modifier to the claim and document the medical necessity for continued services in their medical record.
- Can a physician script be used as the certification or recertification for the plan of care or does it have to be a signature on the plan of care itself?
Answer: A physician script can be used for the plan of care as long as it contains all the components for the plan of care. Please be sure to reference the information in CMS IOM Publication 100-02, Medicare Benefit Policy Manual, Chapter 15, Section 220.1.2 for guidelines on establishing the plan of care.
The payment is based off the certification by a physician or NPP of the plan of care developed by the therapist. They must sign and date your plan of care within 30 days of the implementation of the plan.
Medicare no longer requires a physician script/referral for physical therapy services. The patient can simply come to you directly for services. There however, may be a state requirement for the script, for which you will need to check with your own state. Also, some facilities may require a physician script.
- How long is the plan of care good for?
Answer: The plan of care is good for as long as what you have written in to it, up to 90 days. For example, if your plan of care indicates treatment will be a total of 45 days, then it is only good for 45 days.
- What do I do if the physician hasn’t certified the plan of care, after several attempts?
Answer: The payment for the claim is dependent on the certification of the plan of care. We realize you are at the mercy of the physician or NPP when it comes to this. You must make a concerted effort to obtain this for your records. Indicate in the patient’s medical record what times and dates you tried to receive this information from the provider. Also indicate whether it was a telephone call, fax, or mailed inquiry.
In the event you are asked for medical records and you still do not have the certification to the plan of care, the claim will get denied. Once you have obtained the certification you may appeal the claim for payment.
