Use Code

## **What is the HCPCS code T1020?** HCPCS code T1020 is used for personal care services provided on a per diem basis, typically delivered in the patient's home or community-based settings. However, the code may not be used to identify services provided by home health aide or certified nurse assistant. This includes comprehensive personal care services that may be part of the individualized plan of treatment for patients requiring ongoing support outside traditional hospital nursing facility or institutional settings, such as intermediate care facilities for the mentally retarded (ICF/MR or IMD). T1020 covers assistance such as home health services with personal hygiene, mobility support, meal preparation, medication reminders, and other essential daily activities that enable patients to remain in their preferred living environment beyond settings such as a hospital nursing facility ICF/MR.

## **Documentation requirements** Healthcare providers must establish clear connections between the patient's medical history, current condition, and the specific personal care services being provided. Documentation begins with thorough assessment of the patient's functional abilities, medical condition, and social circumstances. The individualized plan must include: - Detailed evaluation of the patient's ability to perform activities of daily living independently - Assessment of cognitive status and safety awareness in the home environment - Review of medical conditions that impact the patient's ability to maintain personal care - Documentation of family support systems and their capacity to provide assistance This assessment typically involves input from multiple healthcare providers, including registered nurses, social workers, and when applicable, specialists providing physical therapy, respiratory therapy, or speech therapy services. Aside from this, each service period must also be documented with specific details about care provided and the patient's response. Essential documentation elements include: - Established medical necessity - Specific tasks performed during each service period - Patient's physical and emotional status during care delivery - Any changes in condition or functional abilities observed - Communication with family members or other healthcare providers - Safety concerns or incidents that occur during service delivery

## **Billing requirements** T1020 operates under a per diem pricing structure, meaning providers bill for a full day of personal care services regardless of the specific number of hours provided, within reasonable limits established by the payer. The pricing indicator for T1020 typically falls under the "separately priced" category, meaning each unit represents a distinct service day that can be billed independently. However, specific reimbursement rates vary by geographic location, payer requirements, and the level of care intensity required by individual patients.

Frequently asked questions

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.
