For healthcare providers, the key question is not simply what 97755 means. The real question is when the service supports the code, what must be documented, and how the claim should be handled.
97755 CPT code describes an assistive technology assessment performed through direct one-on-one contact, with a written report, in 15-minute units. CMS links the service to outpatient physical therapy, outpatient occupational therapy, and home health PT/OT coverage policies.
What Does 97755 Cover?
The service is an assessment of assistive technology used to restore, augment, or compensate for an existing function, improve functional tasks, or increase environmental accessibility.
A qualifying assessment may involve:
- Testing different technology components or systems
- Evaluating the best interface between the patient and technology
- Determining whether commercial off-the-shelf components are appropriate
- Considering customized components or systems
- Documenting why the selected technology meets the patient’s functional needs
This is why the 97755 CPT code should not be treated as a general therapy treatment code. The service centers on assessment and selection of assistive technology.
Who Should Bill 97755?
CMS guidance identifies occupational therapists (OTs) and physical therapists (PTs) with appropriate assistive-technology knowledge and expertise as the clinicians who should bill this service. The patient must have a clinical need that supports the assessment.
For a provider, the practical test is simple:
Can the note show that specialized assistive-technology assessment was actually performed, rather than routine therapy or training?
If the service is better described by another therapy code, providers should not use 97755 simply because assistive technology was involved. CMS gives CPT 97535 as an example of a more appropriate code when the service is self-care or home-management training.
When Should a Provider Use 97755?
The code is most appropriate when 97755 CPT code is used for a structured assessment of adaptive technology required because of significant functional limitations.
For example, an OT may assess several access methods for a patient with severe upper-extremity impairment. The therapist may compare interfaces, test components, observe functional use, and determine which option best supports the patient’s daily activities.
CMS describes this service as appropriate for patients requiring adaptive technology because of severe impairment.
The assessment may take more than one visit when the patient’s condition or activity tolerance makes a single session impractical. CMS specifically notes that complex cases may require multiple visits.
What Documentation Is Required?
Documentation is one of the most important parts of a clean claim for 97755 CPT code. The record should support the medical necessity of the assessment and explain the nature and complexity of the assistive technology needed. CMS also requires a written report.
A strong note should make these points clear:
1. Patient’s Functional Problem
Describe the impairment and the activity or accessibility problem it creates.
2. Reason for Assistive Technology
Explain why technology is needed and what function it is intended to restore, augment, or compensate for.
3. Assessment Performed
Document the components, systems, interfaces, or options evaluated.
4. Clinical Findings
Record the patient’s response, functional performance, limitations, and relevant observations.
5. Technology Decision
Explain why the selected option, or recommended option, is appropriate.
6. Plan of Care Impact
Show how the assessment affects the patient’s therapy plan or functional goals.
Simply writing “assistive technology assessed” is not enough. The documentation needs to connect the patient’s functional problem, assessment work, clinical reasoning, and technology recommendation.
CMS specifically states that the written report should explain the nature and complexity of the assistive technology required by the patient.
How Are 15-Minute Units Handled?
97755 CPT code is a time-based service reported in 15-minute units. Providers should record the actual time spent performing the billable assessment and follow the applicable payer rules for unit reporting.
Do not assume that every minute spent around the visit is automatically billable. Time spent on unrelated administrative work should not be converted into therapy units.
The medical record should make the service time and assessment activities easy for a reviewer to understand.
97755 vs 97535: What Is the Difference?
This distinction matters when 97755 CPT code and other therapy codes can appear in the same assistive-technology workflow.
97755 is an assessment service focused on evaluating assistive technology and determining an appropriate solution. By contrast, CPT 97535 is used for self-care or home-management training.
CMS specifically warns that when the service is more clearly described by another CPT code, such as 97535, that code should be used instead.
In simple terms:
| Service | More appropriate code |
| Assistive technology assessment and selection | 97755 |
| Self-care or home-management training | 97535 |
The same patient may receive different services at different points in care, but the documentation must support each billed service.
Can 97755 Be Billed With PT or OT Evaluation Codes?
Providers using 97755 CPT code need to pay close attention to NCCI edits.
CMS’s NCCI policy states that 97755 is not separately reportable on the same date of service with a PT evaluation/re-evaluation code 97161–97164 or an OT evaluation/re-evaluation code 97165–97168 when the services are performed by a single practitioner or by two practitioners of the same specialty.
If two different specialties perform the services, CMS notes that an NCCI-associated modifier may allow separate reporting when the edit requirements are met.
This means a provider should not add a modifier automatically just to bypass an edit. First determine whether the services are genuinely distinct and whether the applicable NCCI policy permits separate reporting.
What Is the 2026 Medicare Reimbursement?
The 2026 Medicare Physician Fee Schedule (PFS) provides the framework for payment. CMS explains that PFS payments use RVUs, conversion factors, and geographic practice cost indices (GPCIs), so the amount associated with a claim can vary by locality and circumstances.
For 2026, published PFS data show a national baseline of $37.74 per 15-minute unit for 97755 before locality adjustments and applicable reductions. The CMS 2026 relative-value files are the underlying source for the fee-schedule data.
CMS says its PFS Look-Up Tool provides Medicare payment information for more than 10,000 services, including pricing, RVUs, and payment policies.
What Can Cause a 97755 Claim to Be Denied?
Common risk areas include:
- Weak or missing written report
- Documentation that does not establish medical necessity
- Billing the code for routine therapy or training
- Failing to describe the technology assessment performed
- Unclear connection between functional limitations and the technology recommendation
- Reporting the service with an incompatible PT/OT evaluation on the same date
- Using a modifier without meeting the applicable NCCI requirements
- Relying on a national reimbursement figure instead of the applicable payer and locality rate
A useful internal claim review asks one question:
Could an outside reviewer understand from the note exactly why this assessment was necessary and what professional work was performed?
Provider Billing Example
Consider a patient with severe functional impairment who cannot use a standard control interface for an important daily activity.
An OT evaluates several assistive technology options. The therapist tests different interfaces, observes functional performance, compares the available options, and determines which configuration best meets the patient’s needs. The therapist then prepares a written report explaining the findings and recommendation.
That documentation supports the assessment nature of 97755 CPT code because the clinical work is centered on evaluating and selecting assistive technology, not simply teaching the patient how to perform a routine task.
What Should Providers Check Before Submitting the Claim?
Use this quick checklist:
- Is the service an assistive technology assessment?
- Was there direct one-on-one contact?
- Is the service reported in 15-minute units?
- Does the record explain the patient’s functional limitation?
- Does the written report explain the technology need and assessment findings?
- Is the provider appropriately qualified under the payer’s rules?
- Does the claim comply with PT/OT coding and NCCI edits?
- Does the payer’s coverage policy apply?
- Was the correct locality-specific fee schedule checked?
Final Takeaway
For 97755 CPT code, accurate documentation is not a formality. It is the evidence connecting the billed service to the patient’s functional need and the provider’s professional work.
A strong claim should clearly show what functional problem existed, why assistive technology was considered, what options were assessed, what the assessment found, and how the recommendation affects care.
That approach gives providers a much stronger basis for accurate coding, defensible documentation, and cleaner reimbursement. At Paymedics, our professional team helps providers avoid the billing, coding related issues and achieve long-term profits without compromising on patient-care quality.
