CPT Code 97140: Manual Therapy Billing, Units, and Documentation Guide

While a physical therapist takes 25 minutes for performing hands-on treatment, a minor error in the timing will lead to trouble in filing the insurance claim. CPT Code 97140 represents the services provided under manual therapy, which include joint mobilizations, soft tissue mobilization, and manual traction. But choosing the right procedure code is not enough for getting it paid.

The therapy providers have to keep records of the direct treatment time, the need for the skilled treatment, and the payer-specific rules in billing. The following information will provide knowledge on CPT 97140, Medicare billing units, and billing modifiers.

What Is CPT Code 97140?

The CPT code 97140 describes manual, hands-on physical therapy performed by a qualified practitioner in order to treat musculoskeletal or functional limitations.

According to the American Medical Association, this therapy includes techniques of manual therapy affecting one or several areas of the body, using a fee schedule of 15-minute increments. Such techniques as mobilization, manipulation, manual lymphatic drainage, and manual traction are included.

American Medical Association

As opposed to regular massage therapy, manual therapy should have a specific clinical need and be justified by a practitioner.

Which Treatments Fall Under CPT 97140?

There can be various clinically appropriate manual therapies coded under CPT 97140 by healthcare providers.

• Joint mobilization therapy: Uses controlled motion to increase limited joint motion.
• Soft tissue mobilization therapy: Includes limitations of muscles, fascia, and surrounding structures.
• Myofascial release therapy: Includes restriction of soft tissues and limited motion.
• Manual lymphatic drainage therapy: Uses special techniques to help in lymph flow.

Manual traction therapy: Involves manual traction on clinically appropriate body parts.

Use of a particular technique alone cannot define the medical necessity. It should be connected with documentation and goals of treatment.

How Does CPT 97140 Work in Physical Therapy?

Think about the case of a client who has recently recovered from an injury of the shoulder that has resulted in difficulty in reaching above the head.

The physical therapy notes will need to include the reason for the need of intervention, where on the body the therapist worked, how long did it take, and how the client reacted to the procedure.

For example, one may include the improvement in shoulder range of motion following treatment. Such an objective finding will create a stronger link between the service and the patient’s functional goals.

Physical and occupational therapists frequently apply the 97140 procedure code to cover clinical services that fit the code criteria.

CPT 97140 Billing Units and the Medicare 8-Minute Rule

Procedure code 97140 has a 15-minute billing unit. In outpatient therapy claims under Medicare, the practice has to compute units based on the total number of minutes spent providing the treatment service.

The Medicare 8-Minute Rule determines how many 15-minute units the practice will be able to bill for.

Centers for Medicare & Medicaid Services

Total timed minutes	Maximum billable units
8–22 minutes	1 unit
23–37 minutes	2 units
38–52 minutes	3 units
53–67 minutes	4 units
68–82 minutes	5 units

These ranges apply to the aggregate time spent on timed services, not automatically to each individual CPT code.

Example: Calculating CPT 97140 Units

The following treatment is provided by a therapist:

• Manual therapy: 20 minutes (97140).
• Therapeutic exercise: 10 minutes (97110).
• Total time of treatment: 30 minutes.

According to Medicare, there are two units of time. Based on this example, the practice reports 1 unit of 97140 and 1 unit of 97110 according to time distribution.

But the practice cannot calculate each procedure and not consider the time of combined treatment.

Billing tip: The minutes should be entered separately for each treatment procedure.

CPT 97140 vs. Other Physical Therapy Codes

Therapists frequently combine manual techniques with exercises and functional training. Each procedure must serve a distinct clinical purpose, and documentation must reflect the services the clinician actually performed.

CPT code	Service	Primary distinction
97140	Manual therapy	Skilled hands-on treatment
97110	Therapeutic exercises	Strength, endurance, flexibility, and range-of-motion exercises
97112	Neuromuscular reeducation	Movement, balance, coordination, posture, and proprioceptive training
97530	Therapeutic activities	Dynamic activities that improve functional performance
97124	Massage therapy	Massage techniques such as effleurage, petrissage, and tapotement

The therapy can offer more than one service in a single session, although it is essential for the practice to differentiate the services provided in order to avoid overlapping times of treatment reported.

Also, CMS does not allow reporting of several physical medicine services separately during a single treatment period, except in certain cases.

Which Modifiers Apply to CPT Code 97140?

Modifiers communicate important information about a therapy claim. They may identify the therapy discipline, assistant involvement, medical necessity requirements, or a distinct procedural service.

Common CPT 97140 Modifiers

Modifier	Purpose	Billing consideration
GP	Physical therapy plan of care	Identifies services under a PT plan
GO	Occupational therapy plan of care	Identifies services under an OT plan
CQ	Physical therapist assistant involvement	Applies when Medicare’s assistant participation criteria require it
CO	Occupational therapy assistant involvement	Applies under the relevant Medicare assistant rules
KX	Therapy threshold attestation	Confirms documented medical necessity when the applicable Medicare threshold requires it
59	Distinct procedural service	Use only when a qualifying distinction supports the modifier
XU	Unusual non-overlapping service	May apply to certain distinct services under NCCI rules

Can You Bill CPT 97140 and 97110 Together?

Yes, where the physician provides separately identifiable medical services necessary.

This is because, for instance, the therapist may provide shoulder mobilization using hands and later strengthen the muscles. The practice should identify the intervals separately and apply the correct unit.

Not always does one use 59 where both codes appear on the claim. One should check NCCI edits as well as the payer instructions.

When Does CPT 97140 Require Modifier KX?

For the calendar year 2026, the Medicare set a $2,480 KX modifier threshold for physical therapy and speech-language pathology combined, and a $2,480 threshold for occupational therapy.

In addition, Medicare keeps a $3,000 targeted medical review threshold for each category until the year 2027. Crossing the threshold does not necessarily mean an audit or denial of coverage.

The above figures apply to the calendar year 2026. It is essential to verify the threshold for the current year before processing any other services in any other year.

Documentation Requirements for CPT 97140

Complete treatment notes assist coders in verifying the service and help reviewers understand the reason the patient required manual therapy.

What Should Therapists Document?

1. Clinical data: Give a description of the limitation of function, impairment, or restriction.
2. Body part: Provide the area being manually treated.
3. Procedure: Explain the procedure.
4. Treatment minutes: List minutes of one-to-one treatment.
5. Medical necessity: Describe the medical need for the treatment.
6. Functional goals: Link the treatment to functional goals.
7. Outcome of the patient: Provide the result of the treatment.
8. Signature of provider: Provide the provider’s name and signature.

Weak vs. Strong Documentation

Weak documentation

“The patient received 15 minutes of manual therapy. She tolerated the procedure well.”

Better documentation

“Gave 15 minutes of direct manipulation of the right shoulder joint due to restricted shoulder flexion. Shoulder flexion increased from 110° to 120° with the intervention. The patient noted an improved ability to reach overhead.”

The better example provides details about the body area involved, the type of treatment, the skilled need, the time spent on the procedure, and the documented response.

One response alone does not indicate the need for the whole therapy program.

ICD-10-CM Diagnosis Coding for CPT 97140

The procedure code indicates what was done by the therapist. ICD-10-CM specifies the diagnosis of the patient or the condition of the patient.

Therapy practices should make sure that the diagnosis codes used are selected according to the provider’s documentation, not only for payment purposes.

For instance, the patient could be treated with manual therapy for the diagnosed condition of the shoulder, neck, or any other appropriate diagnosis. The diagnosis must correspond with the condition and laterality specifications.

Prior to filing the claim, the billers must verify that:

• The diagnosis is supported by the records.
• The chosen ICD-10-CM code agrees with the patient’s documentation.
• The payer’s coverage agreement agrees with the situation surrounding the treatment.
• The medical notes show the connection between the procedure and the functional limitation.

Facilities should look at the relevant FY 2027 ICD-10-CM codes for services provided from October 1, 2026 to September 30, 2027.

Common CPT 97140 Claim Denials and Billing Errors

The claim can have the right CPT code but yet face payment issues.

Inaccurate Timed Units

The billing staff can calculate the length of the appointment, not the treatment minutes. This can result in a higher number of units billed.

Solution: Record the direct treatment minutes separately from untimed services, administration, and non-billable time.

Lack of Medical Necessity

A treatment note stating “Manual Therapy was Performed” does not give a lot of information about the skilled treatment provided.

Solution: Relate the treatment performed to findings, goals, and the patient’s needs.

Modifiers that Lack Support

An unneeded modifier or the lack of therapy modifiers can lead to processing issues for the claim.

Solution: Verify the current NCCI edits and the use of modifier guidelines before filing a claim.

Duplicate or Overlapping Services

Using the same duration for two different timed therapy codes leads to improper billing.

Solution: Keep each treatment duration separate and resolve the total number of minutes before units are assigned.

Incomplete Therapy Records

An audit risk may be due to the absence of signatures, insufficient progress notes, and failure to have consistent treatment plans.

Solution: Implement a document verification procedure that would identify incomplete documents before submitting claims to the insurance company.

One of the CPT codes recognized by the CMS that requires medical necessity determination using the KX modifier is CPT 97140.

How Much Does Medicare Reimburse for CPT 97140?

The Medicare payment for the procedure code 97140 is determined based on the appropriate Physician Fee Schedule, geographic adjustments, setting of service delivery, and other payment guidelines.

A practice should not assume a single payment across the nation.

There can be a multiple procedure payment reduction (MPPR) applied by Medicare on the practice expense component of some therapies when the physician reports several appropriate services performed on that particular date.

Other than Medicare, insurers can have varied rates because of the varying contract terms and reimbursement rules.

It is important for the billing team to ensure that they confirm payments through the comparison of contract allowances and claim settlement.

How Practices Can Improve CPT 97140 Billing Accuracy

Therapy billing efficiency entails coordination between providers, coders, and revenue cycle staff.

Create templates for standardization of treatment records. The templates should contain the type of intervention, body part, treatment minutes, and progress toward functionality without creating redundant notes.

Review the minutes before you submit claims. Configure your process for review of the claims so that it reviews the minutes of treatment versus minutes billed.

Monitor denial trends. Make sure to differentiate whether denials are due to coding problems, coverage denials, authorization problems, or medical necessity.

Always be aware of payer guidelines. Make sure to keep track of updates to the payer guidelines by Medicare, commercial insurers, and NCCI.

These all will help the practice to identify claim denials that could have been avoided.
