Clinical & Coding Specifications
Clinical Context
A home health registered nurse (RN) or a non‑nursing practitioner (for example, a certified home health aide supervisor or licensed practical nurse under scope) performs a visit to assist a patient with activities of daily living (ADLs) and self‑care. A typical patient is an older adult recently discharged from hospital after a fall with hip fracture repair, receiving outpatient rehabilitation, and requiring ongoing assistance with bathing, dressing, toileting, ambulation, and medication reminders. The clinical workflow begins with a referral to home health services, an intake assessment by an RN to document baseline ADL deficits, development of a care plan coordinating therapy and durable medical equipment, scheduled skilled or non‑skilled visits to provide direct ADL assistance and teach self‑care techniques, and periodic reassessment to document progress or changes in function. Visits may include ADL task assistance, caregiver training, safety evaluations of the home environment, coordination with physical or occupational therapy, and documentation of functional status changes to justify continued services.
