Thank you for your question aboutCMS157v12 Oncology: Medical and Radiation - Pain Intensity Quantified. The measure has two population criteria: - Population 1: Visits for patients with a diagnosis of cancer who are currently receiving chemotherapy - Population 2: Visits for patients with a diagnosis of cancer who are currently receiving radiation therapy Population 1 is intended to be reported by medical oncologists. The patient-medical oncologist encounter is identified by the CPT E/M and SNOMED-CT office visit codes included in the measure. As specified in the measure logic, for an encounter to be eligible in population 1, there must be a cancer diagnosis that’s active at some point in time during an encounter and chemotherapy administered ("Chemotherapy Administration (OID 2.16.840.1.113883.3.526.3.1027)) on the same day as the encounter or during the 30 days before the date of the encounter AND during the 30 days after the date of the encounter. Population 2 is intended to be reported by radiation oncologists. The patient-radiation oncologist encounter is identified by the radiation treatment management codes included in the measure. These codes are used by the radiation oncologists only "Radiation Treatment Management" (OID 2.16.840.1.113883.3.526.3.1026). To be eligible for the measure, there must be a cancer diagnosis that’s active at some point in time during the radiation treatment management.
