Thank you for your question regarding CMS139v13. According to the measure steward, the National Committee for Quality Assurance (NCQA), as stated in the measure header, a fall risk screening must assess "whether an individual has experienced a fall or problems with gait or balance. A specific screening tool is not required for this measure, however potential screening tools include the Morse Fall Scale and the timed Get-Up-And-Go test." This is further specified in the measure logic and terminology. Fall risk screenings should be identified through codes in the “Falls Screening” value set ( https://vsac.nlm.nih.gov/valueset/2.16.840.1.113883.3.464.1003.118.12.1028/expansion/eCQM%20Update%202024-05-02 ). Clinically equivalent services may be mapped to the codes in the value set. If mapping is done, you should maintain documentation in case of a CMS audit.
