Knowledge Base Article

Earlier this year I wrote about the new CPT codes for physical therapy and occupational therapy evaluations.  Documentation to support therapy services, especially evaluations and plans of care, has always been arduous.  With the new evaluation codes, there is even more to consider – enough to give a therapist a breakdown.  Hopefully this breakdown of the components of the new evaluation codes will help prevent some breakdowns of the psychological type.

CPT is deleting the current PT and OT evaluation and re-evaluation codes (97001-97004) and creating three-tiered codes for the evaluations and one new code per discipline for re-evaluations.  I am including the same evaluation code tables as I posted in my original article and the re-evaluation code descriptions at the end of this article for both physical and occupational therapy.  There are similarities but also differences between the PT and OT evaluation codes.  In general the long descriptions of the new OT codes contain more details of the expected elements.  Both the American Physical Therapy Association (APTA) and the American Occupational Therapy Association (AOTA) have excellent resources on their websites concerning the new code descriptors and required elements.  In this article I want to examine each component of the new physical therapy evaluation codes in more depth.

History

The therapist determines if and if so, how many, personal factors and/or comorbidities the patient has that impact the therapy plan of care (POC).  Personal factors include sex, age, coping styles, social history, education level, profession, lifestyle, character, attitudes, etc.  The therapist will consider the personal factors that could affect the patient’s ability to reach their therapy goals.  Personal factors that exist but do not impact the physical therapy plan of care are not to be considered when selecting an evaluation level.

The patient’s past medical history may identify comorbidities that could impact the patient’s function and ability to progress through a POC.  For example, chronic conditions such as obesity, diabetes, hearing loss, visual deficits, or cognitive deficits could affect the patient’s functional abilities.  A lack of personal factors and/or comorbidities that could impact the POC would be expected in a low complexity evaluation (CPT 97161); 1-2 personal factors and/or comorbidities for a moderate complexity eval (CPT 97162), and 3 or more for a high complexity eval (CPT 97163).

Examination of Body Systems

The therapist uses standardized tests and measures in the examination of body systems.  The evaluation complexity level is associated with the number of elements addressed related to body structures and functions, activity limitations, and/or participation restrictions: 1-2 elements for low complexity; 3 or more elements for moderate complexity; and 4 or more elements for high complexity.  Some important definitions necessary to understand related to the Examination components include:

• Body systems include the circulatory, skeletal, muscular, nervous, respiratory, immune, excretory, integumentary, lymphatic, cardiovascular, reproductive, and digestive systems.  Per information from the APTA website, system reviews for PT evaluations include the following:
• For the cardiovascular/pulmonary system: the assessment of heart rate, respiratory rate, blood pressure, and edema
• For the integumentary system: the assessment of pliability (texture), presence of scar formation, skin color, and skin integrity
• For the musculoskeletal system: the assessment of gross symmetry, gross range of motion, gross strength, height, and weight
• For the neuromuscular system: a general assessment of gross coordinated movement (eg, balance, gait, locomotion, transfers, and transitions) and motor function (motor control and motor learning)
• For communication ability, affect, cognition, language, and learning style: the assessment of the ability to make needs known, consciousness, orientation (person, place, and time), expected emotional/behavioral responses, and learning preferences (eg, learning barriers, education needs)
• Body structures refers to the body’s structural or anatomical parts (e.g., organs or limbs), which are classified according to body systems.
• Body functions are the physiological functions of body systems.
• Activity limitations are difficulty executing tasks, actions or activities.
• Participation restrictions are related to participation in life situations (for example, inability to engage in community social events due to exhaustion).
• The Domains of Activity and Participation as determined by the International Classification of Functioning, Disability, and Health (ICF) include but are not limited to:
• Mobility
• Self‐care
• Domestic life
• Interpersonal interactions and relationships
• Major life areas
• Community, social and civic life

Documentation for the examination of body systems should include objective findings and the expected progression of the patient.  Descriptions of the patient’s specific limitations in activities of daily living (ADLs) also support this element.

Clinical Presentation of the Patient

This addresses the status and mechanism of the patient’s current condition.  Is the clinical presentation of the patient’s condition stable and uncomplicated (low complexity), evolving with changing clinical characteristics (moderate complexity) or evolving with unstable and unpredictable characteristics (high complexity)?

Clinical Decision Making

Based on the composite of the patient’s presentation, the therapist uses his/her clinical judgment to develop the plan of care with goal establishment, prognosis, and probable outcomes.  This component should correlate with the other components already discussed as all of these elements are considered in establishing the POC.  The patients’ condition, personal factors, comorbidities, limitations, and restrictions will relate to how complex the judgment and decision making are that is required to develop a plan and prognosis for the patient. 

Time

Note that this is the “typical time” spent face-to-face with the patient and/or family and is to be used for guidance only.  Low complexity is typically 20 minutes of face-to-face time, moderate complexity 30 minutes and high complexity 45 minutes.  This makes sense as more complex patients should require a longer amount of time to evaluate.

It is also important to note that for now, Medicare does not make a payment difference in the evaluation levels – they are all paid at the same rate.

Good luck to the therapists as they adjust to yet another change in their documentation, coding and billing requirements.  With a successful transition, maybe they will feel like break dancing.

Reevaluation Codes

PT Revaluation

• 97164 - Re-evaluation of physical therapy established plan of care, requiring these components:
• An examination including a review of history and use of standardized tests and measures is required; and
• Revised plan of care using a standardized patient assessment instrument and/or measurable assessment of functional outcome.
• Typically, 20 minutes are spent face-to-face with the patient and/or family.

OT Revaluation

• 97168 - Re-evaluation of occupational therapy established plan of care, requiring these components:
• An assessment of changes in patient functional or medical status with revised plan of care;
• An update to the initial occupational profile to reflect changes in condition or environment that affect future interventions and/or goals; and
• A revised plan of care. A formal reevaluation is performed when there is a documented change in functional status or a significant change to the plan of care is required.
• Typically, 30 minutes are spent face-to-face with the patient and/or family.
