    Clinical & Coding Specifications

    Clinical Context

    A 63-year-old patient with newly diagnosed stage III colorectal adenocarcinoma is enrolled in a practice participating in the Oncology Care Model (OCM). The multispecialty oncology practice bills a monthly enhanced oncology services (MEOS) payment using G9678 for the care coordination and enhanced services furnished to OCM beneficiaries during a given calendar month. The clinical workflow includes the oncologist and designated care team (nurse navigator, social worker, and pharmacist) conducting comprehensive treatment planning, documenting a 13-element care plan, performing medication reconciliation, arranging timely access to systemic therapy, coordinating symptom management and palliative care referrals, and providing 24/7 access to clinicians for acute issues. The practice documents these enhanced services in the patient’s medical record and bills G9678 monthly to reflect the OCM MEOS payment for the enhanced services provided to the OCM beneficiary during that month. Typical sites of service include outpatient oncology clinics, infusion centers, and associated practice locations where care coordination and monthly enhanced services are delivered.
