HCPCS Code T1020: Personal Care Services, Per Diem

Service or procedure code T1020 differs from T1019 in that T1020 is billed per diem (per day) for personal care services provided under an individualized plan of treatment outside of hospitals or nursing facilities, while T1019 is billed in 15-minute increments for similar personal care tasks, allowing for finer time-based billing and documentation. T1020 is intended for one daily charge regardless of hours, and both exclude services by certified nurse assistants or home health aides.

Multiple aides can split the day under T1020 as long as each shift is documented properly and the total care aligns with the plan of treatment; each shift should be billed on a separate claim line or documented according to payer authorization for split shifts, ensuring the aggregate service meets per diem criteria and avoids duplicate billing.

Medical supervision is generally required for personal care services billed with T1020, meaning the care must be coordinated with and overseen by a healthcare professional, with regular monitoring, progress documentation, and coordination to address any medical or health changes.
