CPT® Code 97140

Quick Reference: CPT 97140 (Manual Therapy Techniques)

• Code definition: CPT 97140 describes manual therapy techniques (e.g., mobilization/manipulation, manual lymphatic drainage, manual traction), one or more regions, each 15 minutes of direct one-on-one patient contact. Authoritative CPT coding resources confirm inclusion of joint mobilization, soft tissue mobilization, myofascial release, and manual lymph drainage.
• Timed code -- 8-Minute Rule applies: Medicare requires at least 8 minutes of direct treatment to report one unit. When multiple timed services are performed, total timed minutes determine total billable units and must be allocated appropriately.
• Skilled therapy standard: Documentation must show the service required the specialized skills of a licensed therapist and was reasonable and necessary to improve, restore, or maintain function.
• Bundling and distinct services: Manual therapy may be bundled with other services unless performed on a different anatomical region or separate session. Modifier 59 (or X{EPSU}) may be required when documentation supports distinctness.
• Discipline modifiers: Append GP (physical therapy) or GO (occupational therapy) to identify the therapy plan of care.
• Lymphedema application: CPT 97140 is commonly used for manual lymphatic drainage within Complete Decongestive Therapy (CDT) when medically necessary.
• State authorization rules: Some Medicaid programs (e.g., California Medi-Cal) list 97140 as a Treatment Authorization Required (TAR) code.

1. Clinical Definition & CPT Scope

CPT 97140 is defined as: "Manual therapy techniques (e.g., mobilization/manipulation, manual lymphatic drainage, manual traction), one or more regions, each 15 minutes."

This descriptor establishes three core components:

• Manual (hands-on) intervention
• One or more anatomical regions
• Timed, 15-minute increments of direct one-on-one contact

Authoritative CPT guidance clarifies that 97140 includes:

• Joint mobilization (e.g., glenohumeral, tibiofemoral)
• Soft tissue mobilization
• Myofascial release
• Manual lymphatic drainage (MLD)
• Manual traction

Professional coding references distinguish 97140 from massage therapy (CPT 97124). Myofascial release and therapeutic soft tissue mobilization fall under 97140, not 97124, when delivered for therapeutic intent and functional improvement.

The code is used in orthopedic rehabilitation, neurological recovery, post-surgical mobility restoration, lymphedema management, and other conditions where skilled mobilization is required to restore function.

2. CMS Interpretation & Skilled Therapy Standard

CMS coverage policy requires that therapy services be:

• Reasonable and necessary
• Provided under a written plan of care
• Furnished by qualified personnel
• Directed toward functional improvement, maintenance, or prevention of deterioration

Article A56566 (Outpatient PT/OT Services) confirms that CPT 97140 is recognized within Medicare's outpatient therapy benefit and may be used when medically necessary.

Article A53304 further emphasizes that therapy must require the skills of a licensed therapist and cannot be services that could be safely and effectively performed by unskilled personnel.

In practice, this means documentation must show:

• Clinical assessment and reasoning
• Selection of technique based on pathology
• Ongoing evaluation and modification of intervention
• Objective functional progress

Audit trigger: If documentation describes routine massage or generalized soft tissue work without therapeutic objective or measurable outcome, payers may deny 97140 as non-skilled or not medically necessary.

3. Time Rules, Units & 8-Minute Calculation

CPT 97140 is a timed therapy code. Medicare applies the 8-Minute Rule to determine billable units.

3.1 Minimum Time Threshold

At least 8 minutes of direct treatment is required to bill one unit of 97140. If 7 minutes or fewer are provided, the service is not billable as a timed unit.

3.2 Multiple Timed Services

When multiple timed services are delivered (e.g., 97140 and 97110), total timed minutes determine total units. Units must then be allocated based on documented time per service.

Example:

• 97140: 16 minutes
• 97110: 18 minutes
• Total: 34 minutes → 2 units

Allocation must reflect documented minutes, and time must be recorded per CPT code.

3.3 Assistant Participation

When services are provided in whole or in part by a PTA/OTA, appropriate assistant modifiers may apply under CMS policy.

Documentation requirement: Time must be documented by code. "60-minute therapy session" without code-specific minutes is insufficient in audit review.

4. Documentation & Medical Necessity Requirements

CMS requires that documentation demonstrate both medical necessity and skilled intervention.

4.1 Required Documentation Elements

• Diagnosis supporting therapy
• Functional limitation
• Specific manual technique performed
• Anatomical region(s) treated
• Time per service
• Objective measurements (ROM, strength, edema, pain)
• Progress toward goals

Article A56566 outlines expectations for progress notes, including measurable outcomes and linkage to the plan of care.

4.2 Lymphedema Documentation

When billing 97140 for manual lymphatic drainage, documentation should include:

• Lymphedema diagnosis
• Limb circumference or volume measurements
• Stage and severity
• Skin condition
• Compression therapy plan
• Patient education

Aetna's clinical policy bulletin recognizes manual therapy within lymphedema treatment protocols when criteria are met.

5. Medicare & Commercial Coverage Policies

5.1 Medicare

Medicare covers 97140 when medically necessary and provided under a therapy plan of care.

CMS NCCI Policy Manual governs bundling edits and use of modifier 59.

5.2 Commercial Insurance

Commercial insurers often align with Medicare but may impose visit limits or prior authorization requirements.

• Aetna: Lists 97140 in lymphedema treatment coverage when criteria are satisfied.
• UnitedHealthcare: Includes CPT 97140 among covered outpatient rehabilitation services when medically necessary.

6. Modifier Guidance & NCCI Edits

6.1 GP / GO

Required to identify therapy discipline.

6.2 Modifier 59 (Distinct Procedural Service)

May be used when 97140 is performed on a different anatomical region than another service subject to bundling. NCCI policy outlines criteria for appropriate use.

6.3 Modifier 25

Used by physicians for separately identifiable E/M services on the same date. Therapists do not append modifier 25 to therapy codes.

Compliance warning: Inappropriate use of modifier 59 to bypass NCCI edits without true anatomical distinctness is a common recoupment issue.

7. Code Comparison

Professional coding guidance clearly differentiates 97140 from massage and exercise codes.

8. Real-World Clinical Scenarios

Scenario 1: Post-Surgical Knee Replacement

97140 performed for patellar mobilization and scar tissue release (20 minutes). 97110 for quadriceps strengthening (15 minutes). Documentation includes pre/post flexion measurements.

Scenario 2: Cervical Radiculopathy

Manual cervical traction and joint mobilization (97140) provided for 15 minutes. Neuromuscular reeducation (97112) performed for posture correction.

Scenario 3: Breast Cancer-Related Lymphedema

Manual lymph drainage (97140) performed for 30 minutes within CDT plan. Limb volume decreased 2.5 cm over 4 sessions. Skilled documentation supports ongoing therapy.

9. State Medicaid Guidelines

California (Medi-Cal)

CPT 97140 is listed as a Treatment Authorization Required (TAR) code. Prior approval is necessary.

New York

NY Medicaid requires therapy services to restore function and mandates GP/GO modifiers.

Providers should verify individual state visit limits and authorization requirements.
