Top Physical Therapy CPT Codes - Plus Printable Reference Sheet

by Nicholas Mazzone

xsL3w65-Aug-16-2021-04-14-14-79-PMCurrent procedural terminology (CPT) codes are used to designate services provided by healthcare professionals. We physical therapists receive compensation for our services depending on how we bill using these CPT codes. If we don’t properly bill for our services provided, we could be losing out on valuable income. This article aims to be a useful resource for any PTs using physical therapy CPT codes.

I initially wrote this article in 2016 at the beginning of my career in the field of physical therapy. At the time, I had no idea just how popular the article would become (over 45,000 views as I write this sentence!). In school, we do not learn much, if anything at all, about using CPT codes properly and maximizing reimbursement. However, we are all expected to do so when we begin working. The climate for outpatient PT practice is changing quickly, and so it is more important than ever that we as clinicians understand how to use these codes properly in order to protect our profession and keep our practices thriving.

Since writing this article, I have taken on roles as supervisor and clinic director. These are positions that require a superior knowledge of this subject matter. I've made some edits to this article to help you understand billing procedures with a little more clarity.

Most of the new edits have been to the “Common CPT Codes and Their Usage” section, where you'll find expanded descriptions and other helpful updates.

While most of us got into this profession for the pure enjoyment of working with people who need our help, money still controls our profession, as it does in any other field.

The payment we receive for our services is based on the resource-based relative value scale (RBRVS), which takes into consideration the work performed, the expense to the practice, and the liability and risk in providing the services or procedures.

Now, I don’t know about you, but I sure didn’t learn much about proper billing when I was in PT school. This is one of the topics that we are expected to learn on our own as we embark on our clinical affiliations and careers.

Depending on the physical therapy setting in which you practice, and the site in which you are placed, you will find that people have different opinions on what constitutes proper use of these physical therapy CPT codes.

The Billing Black Hole

I remember my first few months of trying to figure out how to properly bill in order to please the insurance companies and to meet my own clinic’s expectations.

It was odd to me that there was so much widespread uncertainty involved in such a vital part of what we do on a daily basis as clinicians.

  • How could this topic be so sensitive and debatable?
  • Don’t insurance companies want to clearly define what procedures they will be paying for?
  • How will I know how to bill for my patients’ time in the clinic if I don’t truly understand what the codes even mean?

Those tasked with the job of creating and modifying Medicare legislation and reimbursement must have some idea of what they are doing. Payable criteria for each billing code must remain vague and undefined in order to give the insurance company the power to deny our claims if they feel our services aren’t necessary or warranted. To them, if a patient is considered “functional,” they no longer require skilled physical therapy intervention.

When it comes down to it, insurance companies are businesses. Their main job isn’t to provide affordable, high quality healthcare services to all who sign up for their services. Rather, their goal is to turn a profit.

The net profit of the industry over the past 10 years has equaled almost half a trillion dollars. Aetna alone reported a revenue of over $60.3 billion in 2015, a record for the company despite insurance companies sobbing over the passing of the Affordable Care Act in 2010.

Knowledge Is Power When It Comes to Physical Therapy CPT Codes

It would be fruitless to spend our valuable emotional energy struggling with the false idea that everyone who needs quality care will get the necessary funding from their insurance companies, especially since our patients already require so much of this energy on a daily basis.

We need to be informed of how to properly bill for our services to ensure small business success.

We need our private practice clinics to thrive so that they may continue to serve our communities and the patients who need us.

We owe it to our profession to be knowledgeable about how to properly and legally submit claims for our services. The future of reimbursement for physical therapy services may depend on it.

Know Your Value

For the reasons mentioned above, we must make sure that we write a fairly detailed description of the interventions that fall under each billing code we are using to submit our claims. We must be able to make an argument for what we are doing with our patients so that the insurance company sees we are providing high quality care for our patients and aren’t just trying to receive as much money as possible.

We must use the vague and barely defined codes to our advantage.

I know this sounds tough now that many of our clinics have been forced to increase patient volume in an effort to combat decreased reimbursement rates across the board, but the extra effort is worth it. The truth is that we are underpaid for what we provide. We have a doctoral level of education. Let’s show the insurance companies how much we know and how valuable our skill set is.

Don’t let low insurance reimbursement dictate your self worth as a healthcare provider. Nobody else can provide the service we provide.

Simplifying the Billing Process

The main purpose of this article is to not only provide some insight on proper use of physical therapy CPT codes, but to spark some debate on the topic among providers. I want us to air out our frustrations and help each other understand the topic by providing personal accounts and information regarding what these codes mean and the criteria for which they should be utilized.

While the topic of billing can be complex, the focus of this particular article is to provide basic information every physical therapist should know about using these billing codes.

Billing Terminology

In this section, I am going to outline some of the billing terminology that is useful in order to understand how to use physical therapy CPT codes.

Want more information on physical therapy billing and the 8 minute rule? We've broken it down even further.

Untimed codes: The PT is paid a predetermined fee regardless of the time of treatment application or the number of body areas being treated. These codes can only be billed once per treatment session. The time spent providing these services cannot be included in your calculations of timed units and are considered separate billing codes.

Timed codes: These codes are based on the time spent one-on-one with the patient and include only skilled interventions. This time includes the pre-treatment, actual treatment, and post-treatment time.

Pre-treatment time: Includes assessment and management, assessing patient progress, inspection of the tissue or body part, analyzing results of the previous treatment, asking questions, and using clinical judgment to establish the day’s treatment. All of the contact time is administered by the PT or PTA.

Intra-treatment time: Time spent providing the intervention.

Post-treatment time: This includes time spent analyzing the patient’s response to intervention, educating the patient, giving advice, providing documentation, or communicating with other healthcare professionals on the patient’s behalf. The patient must be present during this period of time in order to include it in the time calculation.

Medicare 8 Minute Rule:




Rule of mixed remainders: This is where things tend to get confusing. Try this example: You just spent 24 minutes on exercises in which you billed 1 unit of therapeutic exercise and 1 unit of neuromuscular re-education. Now let’s say you spent an additional 7 minutes performing manual therapy and another 4 minutes using iontophoresis. According to Medicare guidelines (8 Minute Rule), you can combine this extra time (11 minutes total) into one additional unit of manual therapy since the sum of your remainders was more than 8 minutes (you bill for the service that you provided more of, hence, manual therapy in this case).

However, according to American Medical Association (AMA) guidelines, leftover minutes that fall into multiple categories with less than 8 minutes per category cannot be billed for. This is why it is important to know which insurance company follows what guidelines.

Now that we’ve got some of the important details out of the way, let’s start talking about what I believe constitutes each of the used physical therapy CPT codes. I have done extensive research on the topic, only to find that not much information actually exists.

I will be basing the information on my research, what I feel makes sense to me, and what I have learned from coworkers and clinical instructors in the past.


Common Physical Therapy CPT Codes and Their Usage

97110 Therapeutic Exercise: Includes exercises for strengthening, ROM, endurance, and flexibility and must be direct contact time with the patient. Ambulation for endurance training would be included in this category (not gait training!).

Most of the time, people use this code because it feels like the safe bet, however, the intervention performed fits better under the code for therapeutic activity. Therapeutic Activity tends to receive a higher reimbursement rate from insurance companies than therapeutic exercise does, even if it is only a few dollars more (it adds up over the course of a year!).

Therapeutic exercise typically does not require as much skill as therapeutic activities or neuromuscular re-ed does, which may be a reason why the reimbursement is lower. Insurance companies assume that we can provide therapeutic exercise without us being very hands-on with the patient (think riding a recumbent bike).

97112 Neuromuscular Re-education: Activities that facilitate re-education of movement, balance, posture, coordination, and proprioception/kinesthetic sense. You would include time spent kinesiotaping in this category as well as performing stabilization exercises, facilitation or inhibition, desensitization, ergonomic training, improving motor control, and plyometrics.

Foam rolling, for instance, may be included in this category if used for desensitization of a painful region or to facilitate muscle contraction prior to performing exercise. Any activity that requires high-level coordination and cueing may fall in this category since we are attempting to re-train neuromuscular output.

97116 Gait Training: Includes sequencing, training using a modified weight-bearing status, employing assistive devices, and completing turns with proper form. If you are using this code, make sure you are focusing on the biomechanics of the gait cycle in some form or another. Having a patient walk in order to improve cardiovascular health is not considered gait training.

97140 Manual Therapy: Includes soft tissue mobilization, joint mobilization, manipulation, manual traction, muscle energy techniques (performed using resistance applied by PT), and manual lymphatic drainage. Manual resistive exercise can be included in this category or in therapeutic exercise since it requires that resistance be applied by the therapist and may be performed with the goal of improving strength or endurance. You can also consider muscle energy techniques as part of the neuromuscular re-education code.

Manual therapy is typically reimbursed at a lower rate than therapeutic exercise, neuromuscular re-ed, and therapeutic activities. Remember, we are not massage therapists. We are most skilled in exercise prescription and load management. That being said, manual therapy techniques that compliment a well-thought-out exercise program can be very effective. I’d suggest you try not to build a dependency on it.

97150 Group Therapy: PT provides therapeutic procedure to two or more patients at the same time on land or in an aquatic setting. It requires constant attendance by the PT or PTA but not one-on-one time. Medicare requires information about the type of group and number of participants in it. If you see multiple Medicare patients at one time, this is the code you should be billing for. Naturally, the reimbursement rate would be less than if the patient was treated one-on-one.

An example of group therapy may be a Parkinson’s Disease group exercise class or a “back school” program for people with chronic low back pain.

97530 Therapeutic Activities: Includes “dynamic activities” that are designed to improve functional performance. This may include sit-to-stand training, bed mobility, step-ups/stair negotiation, hip-hinge training, squatting mechanics, throwing a ball, swinging a bat or golf club, car transfer training, and training proper lifting mechanics.

This code is reimbursed at a higher rate than therapeutic exercise, which is most likely due to the fact that these activities require a higher level of skill and repetition in order to achieve mastery. For this reason, they require more skilled intervention on our part.

97535 Self-Care/Home Management Training: This includes ADL training, compensatory training, going over safety procedures/instructions, meal preparation, and use of assistive technology devices or adaptive equipment. You can also use this code for teaching wound care techniques, strategies for edema control, safe sleeping positions, use of a home tens unit, traction, or paraffin device, activity modification, setting up a safe home environment, basic household cleaning/chores, and for education on the signs of infection. You can also include transfer/transition training in this code if the patient is having trouble getting up out of a chair, but not if you are using sit to stand for strengthening.

The six basic ADLs are:

  • Eating
  • Bathing
  • Dressing
  • Toileting
  • Transferring
  • Continence

As long as you are working on any of these activities with your patient’s exercise program, you can bill this code. Some of these exercises may include functional IR and ER training (dressing, toileting), fine motor skills (manipulating utensils), pelvic floor muscle exercises (for continence), sit to stand, and improving posture/deep cervical flexor endurance to ensure safe and effective swallowing.

You should not be reporting that your treatments are focused on any of these ADLs if the patient has no problem with performing them or if you already included them in the count for your other codes. Teaching a home exercise program that focuses on improving ROM, flexibility, strength, or endurance falls under the therapeutic exercise code.

This code is typically reimbursed at a higher rate than TA, TE, NMR, and MT. This is due to the fact that you cannot teach self-care with a “hands-off” approach. You must be actively lecturing, demonstrating, and providing literature in order to appropriately perform the tasks required by this CPT code.

97750 Physical Performance Test or Measurement: Includes tests determining function of one or more body areas or measuring an aspect of physical performance including a functional capacity evaluation. A written report must be attached if you are to bill for this code. The following tests and measures would be suitable:

  • Functional capacity evaluations
  • Functional assessments
  • Cybex testing
  • Sensory/pinch/grip tests
  • Sport-specific tests
  • Video analysis of gait, throwing, or running
  • Exertional testing

You can argue that using a goniometer to measure joint range of motion or using manual muscle testing/ergometry would fall under this category as well since they are a piece of the “functional” puzzle, however, I have never used this code for this reason. I would use this code if I decided to administer the Berg Balance Scale (functional assessment) at any point after my initial evaluation.

97761 Prosthetic Training: Includes fitting and training in the use of prosthetic devices as well as assessment of the appropriate device, but does not include fabrication time.

97762 Checkout for Orthotic/Prosthetic Use: Includes evaluation of the effectiveness of an existing orthotic or prosthetic device and recommendation for change.

292**, 295** Strapping: One of the more debatable CPT codes being used by PTs is the set of strapping codes. Strapping can be defined as a procedure involving adhesive strips that promote structure or stability to a joint. Use of McConnell taping techniques that provide added stability, immobility, or promote comfort in the patient may warrant usage of these codes. Some feel that strapping is provided with plaster pieces instead of tape, however I have not come across literature that supports this idea. I will say with confidence that kinesiotaping techniques that promote movement would not fall under this category. McConnell tape is a more rigid, stabilizing tape and would be more appropriate. Kinesiotape should be used with the neuromuscular re-ed code.

90901, 90911 Biofeedback: “Biofeedback therapy is a type of behavioral technique by which information about a normally unconscious, physiologic process is presented to the patient and is demonstrated by a signal to educate the patient for an optimal muscle response. Biofeedback therapy is covered under Medicare only when it is reasonable and necessary for the individual patient for muscle re-education of specific muscle groups or for treating pathological muscle abnormalities of spasticity, incapacitating muscle spasm, or weakness; and more conventional treatments (heat, cold, massage, exercise, support) have not been successful. This therapy is not covered for treatment of ordinary muscle tension states or for psychosomatic conditions.”-

This procedure is commonly used in the pelvic floor arena to aid in retraining of deep muscles to promote continence. It is also used for neuromuscular control of deep cervical flexors and the deeper lumbar stabilizers. This is an untimed code, so no matter how much of this technique is used you may only bill it once. I’ve seen this procedure performed with a modified blood pressure cuff or bladder for external purposes.

Common Billing Blunders

Fixed rate payers: These payers reimburse using a capped daily maximum payment. Contrary to popular belief, this does not mean that they will pay you the same amount no matter how much you bill. You still need to bill for a certain amount of time in order to reach this capped maximum payment for that day. Make sure you bill for the services you provide your patient and nothing less (or more).

Overusing certain codes: Insurance companies pay attention to how often providers use each billing code. If they feel that a provider uses one particular code way more frequently than other providers they deal with, they may place that provider under review (audit).

Under-timing the treatment session: The time we calculate for the service we provide should include pre-treatment time, intra-treatment time, and post-treatment time. Please refer to the definitions listed earlier in this article.

Using the wrong codes: This one may sound obvious, but consider this: You can make the argument that almost any exercise a patient performs can fall under the code therapeutic exercise. While this may be true, the exercise may be better suited under neuromuscular re-education or therapeutic activity. This is important because payers will typically reimburse higher rates for these two codes than they will for therapeutic exercise. Don’t leave money on the table, but also do not stretch the truth in order to receive unwarranted compensation.
