Clinical & Coding Specifications
Clinical Context
A 78-year-old homebound patient with advanced congestive heart failure and multiple comorbidities resides in a skilled nursing facility. The primary care physician provides oversight of the patient’s home health agency plan of care. The physician reviews nursing and therapy documentation, updates the interdisciplinary plan, discusses medication adjustments with the home health team, and coordinates palliative consultations. The provider spends 30 minutes or more in indirect care activities related to a single patient during the calendar day and documents supervision of the home health agency’s implementation of the plan of care, clinical decision-making, and communications with caregivers and facility staff. The clinical workflow typically includes review of recent vitals and lab trends, telephone or secure electronic communications with the home health nurse, revision of orders or goals, and formal documentation in the medical record that supports billing of 99375. The typical site of service is the patient’s residence or a long-term care facility where home health services are delivered; the service is non-face-to-face and centers on oversight and management rather than direct hands-on procedures.
