Manual therapy is commonly used in physical and occupational rehabilitation to address pain, restricted mobility, soft-tissue limitations, joint dysfunction, and movement impairments. However, providing the treatment is only one part of the billing process. Providers must also select the appropriate CPT code, document the skilled service, calculate timed units correctly, and follow payer-specific billing requirements.
Indications and examples of manual therapy 97140 is the main code for manual therapy. This code is used when manual therapy techniques are applied to one or more regions, 15 minutes each. Mobilizations or manipulations, manual lymphatic drainage and manual traction are some examples given by the American Medical Association.
Additional therapy codes may be billed on the same episode of care if conducted on different dates of service with appropriate documentation. Some examples are: 97110 (Therapeutic Exercise) 97112 (Neuromuscular Reeducation) 97530 (Therapeutic Activities) and 97535 (Self-Care/Home Management Training).
Understanding the differences between these services is crucial to correct coding, clear claims and adequate reimbursement.
What Is the CPT Code for Manual Therapy?
CPT 97140 is the primary procedure code used to report manual therapy techniques. The code represents manual therapy performed on one or more regions, with each unit representing 15 minutes of service.
Manual therapy can include techniques such as:
- Joint mobilization or manipulation
- Manual traction
- Manual lymphatic drainage
- Other qualifying hands-on techniques supported by the CPT code description
The treatment should be performed as a skilled service based on the patient’s clinical picture, goals and documentation of the treatment. A common mistake is to label a manual therapy because the therapist did conduct hands on contact.
The code stated should be supported by the rationale for the intervention, the technique, the skill, the amount of time, and the therapeutic intent.
This means that for providers, manual therapy coding should connect the procedure to the patient’s documented impairment and plan of care, not merely the name of the treatment.
Common CPT Codes Used with Manual Therapy
Manual therapy may be included within a larger treatment session. Other CPT codes may be appropriate when the therapist is performing separate services that are supported by documentation.
| CPT Code | General Service | Typical Focus |
| 97140 | Manual therapy | Mobilization, manipulation, manual traction, manual lymphatic drainage |
| 97110 | Therapeutic exercises | Strength, endurance, range of motion, flexibility |
| 97112 | Neuromuscular reeducation | Balance, coordination, posture, movement control |
| 97530 | Therapeutic activities | Functional activities and dynamic tasks |
| 97535 | Self-care/home management training | Daily living skills and home-management activities |
The correct code is based on the service performed and the clinical reason recorded by the provider.
For instance, hands-on joint mobilization is usually not the same as strengthening exercises. Likewise, a functional work conducted to improve transfers or other functional performance may support CPT 97530 where documentation meets the appropriate requirements.
For a thorough explanation of therapeutic activities and timed billing, see the site’s guide to CPT Code 97530: Definition, Billing Guidelines, and Documentation Requirements.
CPT 97140 Billing Guidelines
97140 is a timed CPT code and as such documentation of time is critical. Providers should report units per the applicable payer methodology and document the actual time of skilled care.
For Medicare outpatient therapy, CMS applies timed-code regulations that take into consideration the total minutes of treatment when several 15-minute treatments are delivered. CMS guidance further states the total timed treatment minutes must be consistent with the units stated on the claim.
When a therapist performs manual therapy in addition to therapeutic exercise, the paperwork should explicitly specify the time spent on each timed service. The billing team should then apply the payer’s rules when determining the appropriate units.
The 8-Minute Rule
The 8-minute rule is particularly important for Medicare therapy billing. In general, under the standard Medicare timed-code technique, one unit is reported when the necessary conditions are met and at least 8 minutes of a single timed service are performed. Total timed treatment minutes are used to determine the number of units that may be reported for various timed services.
Providers need to know about timed service standards and the 8-minute rule for Medicare treatment claims. CMS guidance on therapy services explains the applicable Medicare billing requirements and timed-service policies.
Consider a session in which a therapist provides:
- 10 minutes of manual therapy
- 15 minutes of therapeutic exercise
- 8 minutes of neuromuscular reeducation
The billing team should not simply assign one unit to every code without reviewing the applicable timing methodology. The total timed minutes and distribution among services need to support the units reported.
Commercial insurers may use different rules. Therefore, providers should verify the requirements of the specific payer rather than assuming that Medicare’s methodology applies to every claim.
Manual Therapy Documentation Requirements
Accurate documentation is one of the most important parts of manual therapy billing.
A strong treatment note should allow a reviewer to understand:
- Why manual therapy was medically necessary
- What technique was performed
- Which body region was treated
- How long the service lasted
- What skilled intervention the therapist provided
- How the patient responded
- How the treatment relates to the plan of care
- What functional limitation or treatment goal was being addressed
A vague comment such as “manual therapy performed for 15 minutes” may not be enough to support the therapeutic reasons underlying the service.
Manual therapy documentation should clearly support the service performed, including the treatment provided, medical necessity, and other required details. CMS outpatient rehabilitation therapy documentation requirements provide additional guidance on documenting therapy services.
The documentation should identify the technique and its goal, rather than . . . For example, the record could contain a description of the treated location, the specific mobilization or manual technique, the patient impairment that the intervention was appropriate for, the skill of the intervention and the patient response.
The paperwork required may vary based on payer, setting, discipline and policy. For this reason, practices should have a uniform approach to documentation and examine payer-specific standards.
Medical Necessity for Manual Therapy
Medical necessity is yet another key element of CPT 97140 documentation standards.
The manual adjustment must be related to a documented disease or functional disability in the record. The therapist must give the purpose of the approach and how it fits the therapy goals with the patient.
For instance, if someone has impaired joint mobility, they may receive manual therapy under the heading of ‘a well-recognized disability which is impairing functional movement’. The note should provide an obvious connection between the impairment, intervention, response and treatment plan.
The diagnosis alone should not dictate medical necessity. The treatment record must document the grounds for that service being appropriate for that patient.
This is where medical coding services that are reputable can assist your practice in providing uniformity throughout your clinical records, choosing the correct CPT, diagnosing codes and submitting claims.
Manual Therapy CPT Code vs. Other Therapy Codes
Whether an outpatient or a professional claim, this is the most common billing mistake.
CPT 97140 vs. CPT 97110
CPT 97140 is used to certify manual therapy techniques, while CPT 97110 is used to characterize therapeutic exercises.
An exercise programmed designed to enhance strength, flexibility, endurance or range of motion is not a physical intervention that involves the use of hands. If both services are provided, the documentation must clearly distinguish between the two services.
CPT 97140 vs. CPT 97112
CPT 97112 covers neuromuscular reeducation for movement, balance, coordination, posture, and proprioception.
If providers bill both 97140 and 97112, the documentation must show that they performed the services independently and used each service for a distinct treatment purpose.
CPT 97140 vs. CPT 97530
CPT 97530 is for therapeutic activities with direct patient contact and functional performance. The service may include activities such as transfers, functional reaching, lifting, carrying, or other goal-directed tasks.
The difference between 97140 and 97530 is therefore based on the service provided and its purpose, not just the fact that both occur during a physical therapy visit.
For additional information, see the site’s guide to Occupational Therapy CPT Codes, which covers several therapy procedure categories and related billing considerations.
Modifiers for Manual Therapy Claims
Modifiers provide additional information about how a service was performed or billed. However, they should not be added automatically.
Depending on the discipline, payer, provider involvement, and claim circumstances, therapy claims may involve modifiers such as:
- GP – Services delivered under a physical therapy plan of care when applicable
- GO – Services delivered under an occupational therapy plan of care when applicable
- CQ – Applicable Medicare reporting for qualifying services furnished by a physical therapist assistant
- CO – Applicable Medicare reporting for qualifying services furnished by an occupational therapy assistant
- 59 – Distinct procedural service when the reporting requirements are met
CQ and CO requirements apply to applicable Medicare Part B therapy services that utilize PTAs and OTAs, as appropriate under the agency’s guidelines, the CMS said.
Don’t report modifier 59 just because several therapy codes are on the same claim. There should be circumstances that would demand reporting the services separately based on applicable coding and payer requirements.
Because commercial payer policies can differ, billing teams should verify the policy’s current status before submitting claims.
Common Manual Therapy Billing Errors
Even if the correct CPT code is used, a claim can be denied for documentation, units, authorization, or payer reasons.
Common manual therapy billing errors include:
Reporting Unsupported Units
Billing multiple units without documenting the time spent with the patient can create discrepancies between the medical record and the claim.
Using 97140 for Every Hands-On Service
Not every hands-on interaction automatically supports 97140. The actual technique and clinical purpose should match the code definition.
Combining Distinct Services Without Support
When billing multiple timed therapy codes, providers must clearly document each service. The documentation should support the time reported for each service.
Adding Modifiers Automatically
Modifiers should reflect actual billing circumstances. Adding a modifier to overcome an edit without documentation supporting its use can create another billing problem.
Ignoring Authorization Requirements
Some payers will require prior authorization or visit limits for therapy services. Verify eligibility and authorization before billing any services when applicable.
Failing to Verify Payer Rules
Medicare procedures don’t translate to the commercial payer. Having a “standard” way to verify insurance eligibility will result in you having the knowledge of payer rules and what benefits and authorizations need to be in place prior to submitting the claim.
How Accurate Coding Affects Manual Therapy Reimbursement
Reimbursement is based on the payer, the contract, the patient’s benefits, medical necessity, authorization, the location, and the payers’ reimbursement rules. Coding does not guaranty payment.
Practices can also use accounts receivable management services to track outstanding therapy claims and follow up on unpaid balances.
A complete billing workflow should connect:
Documentation → Coding → Charge Entry → Claim Submission → Payer Adjudication → Payment Posting → Denial Follow-Up
This is where the billing staff comes in for a therapy office. You can also check these claims to make sure they were properly coded and documented, claims can be submitted, unapplied balances can be seen, and these can be deliberately appealed.
Additionally, practitioners might use a proprietary AR product to track open therapy claims, monitor duplicate payments, or for other reasons.
When Should a Practice Consider Outsourcing Physical Therapy Billing?
Lack of time to manage therapy billing in-house can be even more challenging for your staff – they’re busy billing, coding and submitting claims, managing payor relationships and unpaid balances, obtaining authorizations, and posting payments – all while trying to fend off denials.
Admin outsourcing Consider whether any administrative functions can be outsourced to another provider and be managed by the company.
For practices seeking physical therapy billing support, the process may start with an assessment of the current process. Important areas include:
- CPT and ICD-10 coding accuracy
- Documentation-to-charge consistency
- Authorization tracking
- Claim submission
- Rejection management
- Denial follow-up
- Payment posting
- A/R follow-up
- Payer-specific billing requirements
Manual therapy may also be part of hospital-based rehabilitation services, making hospital billing services relevant when therapy is provided within a facility setting.
If these functions create excessive administrative work, practices should consider medical billing services that can support the revenue cycle from claim filing through payment collection.
Choosing a Medical Billing Partner for Therapy Claims
Therapy practices should consider more than just claim submission when choosing a billing company.
Ask whether the billing team understands:
- Timed CPT codes
- Therapy documentation
- Modifier requirements
- Medicare billing rules
- Commercial payer differences
- Authorization requirements
- Denial management
- A/R follow-up
- Coding audits and claim reviews
Practices can use this workflow when providers work across multiple specialties. Staff program specialty-specific services according to each provider’s specialty. Example specialties are podiatry, family practice, internal medicine, wound care, cardiology, etc.
A billing partner may also support medical credentialing services when therapists need payer enrollment, recredentialing, or ongoing enrollment assistance.
The optimum procedure when outsourcing physical therapy billing will include not just clinical documentation, but also the business end of revenue cycle management.
Final Takeaway
There is more to billing accurately for manual therapy than selecting a procedure code. Manual therapy is most often reported using CPT number 97140.
Provider shall ensure documentation supports the completed clinical intent, time, units, modifiers, diagnosis code and payer requirements in conjunction with the complete documentation.
Other codes may be appropriate if performed separately and if documentation supports them: 97110, 97112, 97530 and 97535 The idea is to define your service to appropriately capture the therapy offered. It’s not just picking a code based on the general type of appointment.
Providers need to know about timed service standards and the 8-minute rule for Medicare treatment claims. CMS guidance says the verified timed treatment minutes should match the units billed.
A systematic billing method allows practitioners to recognize coding issues, monitor payer requirements, follow up on aging claims, and keep the revenue cycle on track with medical billing services in Rhode Island.

Is CPT 97140 a timed code?
Yes. Providers report CPT 97140 in 15-minute units and should follow the applicable payer’s timed-service methodology when determining billable units.
Can CPT 97140 be billed with 97110?
In some cases, providers can bill both codes when they perform the services separately, document them properly, and establish their clinical necessity. Check the rules for coding and bundling that apply to the payer before billing.
What documentation is required for CPT 97140?
The documentation must show that manual therapy was medically necessary and required skilled care. It should describe the treatment performed, the area treated, treatment time, the patient’s response, and how the service relates to the plan of care and functional goals.
Does CPT 97140 always require modifier 59?
No. Providers do not need modifier 59 when billing 97140. Use this modifier only when the service meets the requirements for a distinct procedural service and the documentation supports its use.
Does the 8-minute rule apply to manual therapy?
When providers bill 97140 as a timed service under Medicare outpatient therapy, they must follow Medicare’s timed-code rules. The provider should check the total timed treatment minutes and related unit rules but not put a generic rule for each payer.
How can physical therapy practices improve manual therapy billing?
Automate link documentation, CPT & diagnosis coding, authorizations, submission, posting and denial management to get some time back. If your practice wants a touch more revenue cycle automation, you also have the option of outsourcing some of these responsibilities to an external medical billing service.
