For patients age 18 and older who had lumbar discectomy/laminectomy procedure, functional status is rated by the patient as less than or equal to 22 OR a change of 30 points or greater on the Oswestry Disability Index (ODI version 2.1a) * at three months (6 to 20 weeks) postoperatively
* hereafter referred to as ODI
This measure is to be submitted each time a patient undergoes a lumbar discectomy/laminectomy during the denominator identification period. This measure may be submitted by Merit-based Incentive Payment System (MIPS) eligible clinicians who perform the quality actions described in the measure based on the services provided and the measure-specific denominator coding.
NOTE: This measure is a target-based measure with two ways to meet the numerator; either a postoperative ODI score that is less than or equal to 22 OR a change of 30 points or greater from the preoperative to postoperative score. It is expressed as a proportion or rate. Patients having received a lumbar discectomy/laminectomy procedure who are not assessed for functional status postoperatively remain in the denominator and are considered as not meeting the target. The measure intent is that MIPS eligible clinicians will submit all denominator eligible procedures to be utilized for performance calculation.
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.

All eligible patients whose functional status is less than or equal to 22 OR a change of 30 points or greater on the Oswestry Disability Index (ODI version 2.1a) at three months (6 to 20 weeks) postoperatively
Measure Assessment Period (Performance Period) - The period of time following the procedure date that is in which a postoperative ODI functional status score can be obtained.
Preoperative Assessment Oswestry Disability Index (ODI version 2.1a) - A preoperative ODI functional assessment score can be obtained from the patient any time up to three months preoperatively, inclusive of the date of the procedure. Assessment scores obtained more than three months before the procedure will not be used for measure calculation.
Postoperative Assessment Oswestry Disability Index (ODI version 2.1a) - A postoperative ODI functional assessment score can be obtained from the patient three months (6 to 20 weeks) after the date of procedure. Assessment scores obtained prior to six weeks and after twenty weeks postoperatively will not be used for measure calculation. ODI can be obtained below or at the following link https://eprovide.mapi- trust.org/instruments/oswestry-disability-index
Functional Status Target #1 - A patient who is assessed postoperatively at three months (6 to 20 weeks) after the procedure rates their functional status as less than or equal to 22.
Functional Status Target #2 - A patient who does not meet Functional Status Target #1 or =is assessed both preoperatively within 3 months prior to the procedure AND postoperatively at three months (6 to 20 weeks) after the procedure AND the change is greater than or equal to 30 points.
NUMERATOR NOTE: It is recommended that both a preoperative and postoperative be administered to the patient increasing chances that one of the numerator targets will be met. The following situations are those in which the numerator target cannot be reached and Performance Not Met M1049 is submitted.
- ODI is not administered postoperatively at three months (6 to 20 weeks)
- Functional status is measured using a different patient reported functional status tool or ODI version
- Postoperative ODI is administered less than 6 weeks or greater than 20 weeks (3 month window)
- Postoperative ODI is greater than 22 and no valid preoperative ODI to measure change
- Preoperative ODI (to measure change) is administered beyond the three month timeframe prior to and including the date of procedure (e.g. 6 months before procedure)
Performance Met: Functional status measured by the Oswestry Disability Index (ODI version 2.1a) at three months (6 – 20 weeks) postoperatively was less than or equal to 22 OR Functional status measured by the ODI version 2.1a within three months preoperatively AND at three months (6 - 20 weeks) postoperatively demonstrated a change of 30 points or greater (G2144)
Performance Not Met: Functional status was not measured by the Oswestry Disability Index (ODI version 2.1a) at three months (6 - 20 weeks) postoperatively (M1049)
Performance Not Met: Functional status measured by the Oswestry Disability Index (ODI version 2.1a) at three months (6 – 20 weeks) postoperatively was greater than 22 AND Functional status measured by the ODI version 2.1a within three months preoperatively AND at three months (6 - 20 weeks) postoperatively demonstrated a change of less than 30 points (G2145)
Mechanical low back functional status (LBP) remains the second most common symptom-related reason for seeing a physician in the United States. Of the US population, 85% will experience an episode of mechanical LBP at some point in their lifetime. For individuals younger than 45 years, LBP represents the most common cause of disability and is generally associated with a work-related injury. It is the third most common reason for disability for individuals older than 45 years. The prevalence of serious mechanical LBP (persisting > 2 wk) is 14%, while the prevalence of true sciatica is approximately 2%.
Overall, spine surgery rates have declined slightly from 2002-2007, but the rate of complex fusion procedures increased 15-fold, from 1.3 to 19.9 per 100,000 Medicare beneficiaries. Complications increased with increasing surgical invasiveness, from 2.3% among patients having decompression alone to 5.6% among those having complex fusions. After adjustment for age, comorbidity, previous spine surgery, and other features, the odds ratio (OR) of life-threatening complications for complex fusion compared with decompression alone was 2.95 (95% confidence interval [CI], 2.50- 3.49). A similar pattern was observed for rehospitalization within 30 days, which occurred for 7.8% of patients undergoing decompression and 13.0% having a complex fusion (adjusted OR, 1.94; 95% CI, 1.74-2.17). Adjusted mean hospital charges for complex fusion procedures were US $80,888 compared with US $23,724 for decompression alone (Deyo, R. JAMA 2010). The MNCM Spine Surgery Measure development workgroup developed patient reported outcome measures for two populations of patients undergoing different lumbar spine procedures, a more complex procedure (lumbar fusion) and a second procedure that represented the most common procedure CPT code 63030 for the most common diagnosis of disc herniation. In 2018, the development workgroup reconvened and redesigned the measure construct to a target-based measure and additionally expanded the denominator for this measure to include all lumbar discectomy laminectomy procedures
Rationale for measure construct and calculation change:
The target was derived from a study “Determination of the Oswestry Disability Index score equivalent to a "satisfactory symptom state" in patients undergoing surgery for degenerative disorders of the lumbar spine-a Spine Tango registrybased study”. vanHooff, ML et al Spine J. 2016 Oct;16(10):1221-1230. Patient Acceptable Symptom State (PASS), the highest level of symptom beyond which patients consider themselves well. PASS was compared to post-op ODI to determine an equivalent ODI threshold. ODI score less than or equal to 22 indicates the achievement of an acceptable symptom state and can be used as a criterion for treatment success. [AUC]: 0.89 [sensitivity: 78.3%, specificity: 82.1%] for 1 year follow-up]. The OR benchmark of change (30) derived from MNCM data (3 years); the average change in points of patients that did achieve the target of less than or equal to 22.
Rationale for the expansion of the denominator and addition of exclusions:
During the original development of this measure, the intent was to have a homogeneous population procedure that represented the most common procedure CPT code 63030 for the most common diagnosis of disc herniation. This strategy did not translate well from ICD-9 to ICD-10 diagnosis codes and the volume of eligible denominator patients dropped significantly. In 2018, the MNCM development workgroup reconvened for measure construct redesign and adopted a broader denominator population; all applicable discectomy laminectomy procedure codes and not limited by a type of diagnosis (includes all). With this decision, the workgroup decided to adopt the same exclusions for the spine fusion population and added exclusions for spine related cancer, acute fracture or infection, idiopathic or congenital scoliosis.
Clinical Recommendation Statements
Journal of Neurosurgery guidelines indicate that there is no evidence that conflicts with the previous recommendations published in the original version of the guideline. This recommendation is for the use of a reliable, valid and responsive outcomes instrument to assess functional outcome in lumbar spinal fusion patients. It is recommended that when assessing functional outcome in patients treated for low-back pain due to degenerative disease, a reliable, valid, and responsive outcomes instrument, such as the disease-specific Oswestry Disability Index (ODI), be used (Level II evidence).
