High Priority Status: Yes / Outcome

CBE Number: N/A

Measure Description:

Percentage of patients that had a thyroidectomy and/or parathyroidectomy and experienced recurrent laryngeal nerve injury resulting in vocal cord paresis or palsy.


This measure is to be submitted each time a thyroidectomy or parathyroidectomy is performed during the performance period. This measure may be submitted by clinicians based on the services provided and the measure-specific denominator coding.


Patients undergoing a thyroidectomy and/or parathyroidectomy procedure.


Patients that experience a laryngeal nerve injury documented following thyroidectomy and/or parathyroidectomy procedure or no laryngeal nerve function documented post procedure.

Numerator Exclusions:

  1. Patients diagnosed with cancer where a nerve has previously been removed for tumor control.
  2. Patient with a history of nerve injury prior to the thyroidectomy and/or parathyroidectomy.
  3. Patients undergoing concurrent total laryngectomy.

INVERSE MEASURE – A lower calculated performance rate for this measure indicates better clinical care or control. The “Performance Not Met” numerator option for this measure is the representation of the better clinical quality or control. Submitting that numerator option will produce a performance rate that trends closer to 0%, as quality increases. For inverse measures, a rate of 100% means all of the denominator eligible patients did not receive the appropriate care or were not in proper control.
