Clinical Context
A typical patient is a 74-year-old Medicare beneficiary with multiple chronic conditions such as congestive heart failure, chronic obstructive pulmonary disease, and type 2 diabetes mellitus. The patient receives primary care in an outpatient clinic or via a home health program. The provider delegates care coordination tasks to clinical staff (nurse, licensed practical nurse, medical assistant) who spend time each calendar month under the provider’s direction performing activities such as medication reconciliation, monitoring adherence, arranging specialty referrals, communicating with home health or social work, and documenting care plan updates in the electronic health record. The team documents the start and stop times of clinical staff work, ensuring at least 20 minutes of provider-directed staff time in the calendar month to bill 99490. Typical sites of service include outpatient office visits, patient homes, and home health settings where non-face-to-face care management and coordination occur. The workflow includes an initial assessment of chronic condition burden, creation or update of a comprehensive care plan, monthly follow-up contacts (phone, telehealth platform, or chart review) by clinical staff, and escalation to the provider when clinical changes or medication adjustments are needed.
