Physical therapy evaluation: low complexity, 20 minutes
A low complexity physical therapy evaluation requiring 20 minutes of face-to-face time with the patient and/or family. This evaluation typically involves a history with no personal factors and/or comorbidities that impact the plan of care, an examination of 1-2 elements from any of the following areas: body region, body system, or functional status, a clinical presentation with stable and uncomplicated characteristics, and a clinical decision-making process of low complexity. The purpose is to establish a diagnosis, prognosis, and initial plan of care.
Clinical Indications
- Simple musculoskeletal complaints such as minor sprains or strains with a clear mechanism of injury.
- Post-operative assessment for routine, uncomplicated orthopedic procedures (e.g., immediately post-casting for a simple fracture).
- Mild gait disturbance due to non-neurological causes, requiring basic assessment.
- Patients presenting with a single, clearly identifiable physical therapy problem.
- Assessment for basic strengthening, flexibility, or balance programs.
Procedure Steps
- Patient History: Gathering information on the current condition, past medical history, and social history, with a focus on limited personal factors or comorbidities that do not significantly impact the plan of care.
- Systems Review (as indicated): A brief review of physiological systems pertinent to the chief complaint.
- Physical Examination: Performing objective tests and measures, typically focusing on 1-2 body regions or systems (e.g., basic range of motion, manual muscle testing of key groups, palpation, simple functional tests).
- Evaluation and Diagnosis: Analyzing findings to determine the patient's physical therapy diagnosis and prognosis based on low complexity clinical presentation.
- Plan of Care Development: Establishing a low complexity, patient-centered plan of care, including initial interventions, frequency, duration, and discharge planning.
- Documentation: Thoroughly documenting all findings, assessment, and the established plan of care, including the 20 minutes of face-to-face time.
Coding Guidelines
- Time Component: Code 97161 requires a minimum of 20 minutes of face-to-face time with the patient and/or family for evaluation. If the total time significantly exceeds this or the complexity is higher, codes 97162 or 97163 may be more appropriate if all other criteria for those codes are met.
- Complexity Levels: Physical therapy evaluations are tiered into low (97161), moderate (97162), and high (97163) complexity based on four key components: history, examination, clinical presentation, and clinical decision-making. Documentation must clearly support the chosen complexity level.
- Billing Frequency: This code is typically billed once per episode of care for the initial evaluation by a qualified physical therapist. Subsequent evaluations for a new problem or a significant change in condition may warrant another evaluation code.
- Documentation Requirements: Clinical documentation must clearly justify the low complexity of the evaluation, detailing the components of the history, examination findings, clinical decision-making process, and the recorded time.
- Qualified Professional: The evaluation must be performed by a qualified physical therapist. Services performed by a physical therapist assistant are not billable under this code.
