Clinical & Coding Specifications
Clinical Context
A homebound adult receiving intermittent home health services after hospital discharge requires assistance with activities of daily living and basic nursing-related tasks. A home health aide visits the patient in the home health or hospice setting to provide direct personal care such as bathing, dressing, toileting, ambulation support, and basic observation of the patients condition. Services are recorded in 15-minute time units and billed using HCPCS Level II code G0156. The workflow includes referral from the home health or hospice plan of care, aide visit documentation of time and services rendered, supervision by a registered nurse or hospice clinician per the plan, and submission of claims with the appropriate modifier when services are provided in group settings or to multiple patients concurrently.
