A patient-reported outcome measure of risk-adjusted change in functional status for patients aged 14 years+ with knee impairments. The change in functional status (FS) is assessed using the Knee FS patient-reported outcome measure (PROM) (©2009-2019 Focus on Therapeutic Outcomes, Inc.). The measure is adjusted to patient characteristics known to be associated with FS outcomes (risk adjusted) and used as a performance measure at the patient level, at the individual clinician, and at the clinic level to assess quality. The measure is available as a computer adaptive test, for reduced patient burden, or a short form (static measure)
This outcome measure is to be submitted once per Treatment Episode for all patients with a functional deficit related to the knee. This is an outcome measure, and its calculation requires submitting of the patient’s FS PROM score, as a minimum, at the start (Initial Evaluation or Intake) and again at the conclusion (Discharge) of a Treatment Episode. The Initial Evaluation score is recorded during the first treatment encounter, and the Discharge score is recorded at or near the conclusion of the final treatment encounter. It is anticipated that Merit-based Incentive Payment System (MIPS) eligible clinicians providing treatment for functional knee deficits will submit this measure.
Functional Deficit – Limitation or impairment of physical abilities/function resulting in evaluation and inclusion in a treatment plan of care.
Treatment Episode –A Treatment Episode is defined as beginning with an Initial Evaluation for a functional knee deficit, progressing through treatment without interruption (for example a hospitalization or surgical intervention), and ending with Discharge signifying that the treatment has been completed. A patient currently under clinical care for a knee deficit remains in a single Treatment Episode until the Discharge is conducted and documented by the MIPS eligible clinician.
Initial Evaluation – An Initial Evaluation is the first encounter for a functional deficit involving the knee and includes an evaluation (CPT 97161, 97162, 97163, 97165, 97166, 97167, 99201, 99202, 99203, 99204, 99205, 99212, 99213, 99214, 99215, 98940, 98941, 98942, or 98943), or an Initial Evaluation Status M-code (M1106). A patient presenting with a knee impairment, who has had an interruption of a Treatment Episode for the same functional knee deficit secondary to an appropriate reason like hospitalization or surgical intervention, is an Initial Evaluation.
Discharge– Discharge is accompanied by a treatment finalization and evaluation completion M-Code (M1009) identifying the close of a Treatment Episode for the same knee deficit identified at the Initial Evaluation and documented by a Discharge report by the MIPS eligible clinician. An interruption in clinical care for an appropriate reason like hospitalization or surgical intervention requires a discharge from the current Treatment Episode.
Encounter – A face to face visit between the patient and the provider for the purpose of assessing and/or improving a functional deficit.
Patient Reported – The patient directly provides answers to the FS measure items using a standardized, reliable and valid, computerized adaptive testing or short form (paper and pencil) method. If the patient cannot reliably respond independently (e.g. in the presence of cognitive deficits), a suitable proxy may provide answers.
Measure Submission Type:
Measure data may be submitted by individual MIPS eligible clinicians, groups, or third-party intermediaries. The listed denominator criteria are used to identify the intended patient population. The numerator options included in this specification are used to submit the quality actions as allowed by the measure. The quality-data codes listed do not need to be submitted by MIPS eligible clinicians, groups, or third-party intermediaries that utilize this modality for submissions; however, these codes may be submitted for those third-party intermediaries that utilize Medicare Part B claims data. For more information regarding Application Programming Interface (API), please refer to the Quality Payment Program (QPP) website.

Patients who were presented with the Knee FS PROM at Initial Evaluation (Intake) and at or near Discharge (Status) for the purpose of calculating the patient’s Risk-Adjusted Functional Status Change Residual Score
Patient’s Functional Status Score – A functional status score is produced when the patient completes the functional status patient-reported outcome measure (either by short form or computerized adaptive testing administration). The functional status score is continuous and linear. Scores range from 0 to 100 with higher scores meaning higher functional abilities. The measure is standardized, and the scores are validated for the measurement of function for this population.
Patient’s Functional Status Change Score – A functional status change score is calculated by subtracting the Patient’s Functional Status Score at Admission Initial Evaluation from the Patient’s Functional Status Score at Discharge.
Predicted Functional Status Change Score – Functional Status Change Scores for patients are risk adjusted using multiple linear regression methods that include the following independent variables: Patient’s Functional Status Score at Initial Evaluation, patient age, symptom acuity, surgical history, gender, specific co- morbidities, use of medication for the condition at Initial Evaluation, exercise history, history of previous treatment for the condition and type of post-surgical status. The Patient’s Functional Status Change Score is the dependent variable. For each patient completing a functional status assessment at Initial Evaluation (Intake), the regression model provides a risk-adjusted prediction of functional status change at Discharge.
Risk-Adjusted Functional Status Change Residual Score – The difference between the raw non-risk- adjusted Patient’s Functional Status Change Score and the Risk-Adjusted Predicted Functional Status Change Score (raw minus predicted) is the Risk-Adjusted Functional Status Change Residual Score, which is in the same units as the Patient’s Functional Status Scores, and should be interpreted as the unit of functional status change different than predicted given the risk-adjustment variables of the patient being treated. As such, the Risk-Adjusted Residual Change Score represents Risk-Adjusted Change corrected for the level of severity of the patient. Risk-Adjusted Residual Change Scores of zero (0) or greater (> 0) should be interpreted as functional status change scores that were predicted or better than predicted given the risk- adjustment variables of the patient, and risk-adjusted residual change scores less than zero (< 0) should be interpreted as functional status change scores that were less than predicted given the risk-adjustment variables of the patient. Aggregated Risk-Adjusted Residual Scores allow meaningful comparisons amongst clinicians or clinics.
Performance Met: Risk-Adjusted Functional Status Change Residual Score for the knee impairment successfully calculated and the score was equal to zero (0) or greater than zero (> 0) (G8647)
Performance Not Met: Risk-Adjusted Functional Status Change Residual Score for the knee impairment successfully calculated and the score was less than zero (< 0) (G8648)
Denominator Exception: Ongoing care not indicated, patient seen only 1-2 visits (e.g., home program only, referred to another provider or facility, consultation only) (M1108)
Denominator Exception: Ongoing care not indicated, patient discharged after only 1-2 visits due to specific medical events, documented in the medical record that make the treatment episode impossible such as the patient becomes hospitalized or scheduled for surgery or hospitalized (M1109)
Denominator Exception: Ongoing care not indicated, patient self-discharged early and seen only 1-2 visits (e.g., financial or insurance reasons, transportation problems, or reason unknown) (M1110)
Denominator Exception: Patient refused to participate (G9726)
Performance Not Met: Risk-Adjusted Functional Status Change Residual Score for the knee impairment not measured because the patient did not complete the Knee FS PROM at Initial Evaluation and/or near Discharge, reason not given (G8650)
Functional deficits are common in the general population and are costly to the individual, their family, and society. Improved functional status has been associated with greater quality of life, self-efficacy, improved financial well-being, and lower future medical costs. Improving functional status in people seeking rehabilitation has become a goal of the American Physical Therapy Association. Therefore, measuring change in functional status is important for providers treating patients in rehabilitation and can be used to assess the success of treatment and direct modification of treatment.
Change in functional status represents the Activities and Participation domain of the International Classification of Functioning, Disability and Health. If treatment is designed to improve the functional deficit, it is logical to assess functional status at discharge using a standardized score to determine if treatment improved the functional status of the patient over the treatment episode.
The National Quality Measures Clearinghouse has approved the measurement of change in functional status, using this measure. (NQMC-1873)
Clinical Recommendation Statements
The American Physical Therapy Association (APTA), in their Guide to Physical Therapist Practice, described five recommended elements of patient management: examination, evaluation, diagnosis, prognosis and intervention. The elements were intended to direct therapists in their approach to patient treatment for the purpose of optimizing patient outcomes. The APTA clearly identifies functional status data as one of the major forms of data to be collected for patients receiving rehabilitation. The functional status measures should be used to assist in the planning, implementation and modification of treatment interventions and should be used as measures of outcomes. The current functional status scores can be used by therapists to fulfill the recommended methods of the APTA in the management of patients in rehabilitation.
