Use Code

## **What is Attendant Care?** Attendant care is non-medical, hands-on support that helps people perform activities of daily living and instrumental tasks such as bathing, dressing, grooming, toileting, mobility, meal prep, light housekeeping, and safety checks. Services are typically delivered in the home or community under an individualized plan and fall under various home care services benefits administered by Medicaid or commercial plans. Minimal equipment is required beyond safe-transfer aids and household supplies. S5125 describes one 15-minute unit of attendant care. It is distinct from home health care services and home health services that involve skilled nursing care, wound care, occupational therapy, respiratory therapy, or visits by a registered nurse, licensed practical nurse, or certified nurse assistant under a clinical episode of care. Attendant care focuses on personal care services that maintain independence, reduce risk, and support comfort at home or during palliative care. S5125 is generally not billed in institutional settings such as a nursing facility or an intermediate care facility unless a payer explicitly allows it.

## **S5125 documentation requirements** Accurate, task-level records keep claims clean and support authorization and audits. ### **Eligibility and plan of care** Maintain an individualized plan that specifies functional needs, frequency, caregiver qualifications, and safety precautions. Include payer authorization details and service limits. ### **Visit logs and timekeeping** For every encounter, record date, start/stop times, total minutes, location, and caregiver name or ID. Logs must identify services provided for each unit of time. ### **Task details and outcomes** Document the ADLs/IADLs completed, cues or hands-on help given, and patient response or barriers. Note any training on safe mobility or transfer techniques. ### **Changes in condition and escalation** Record new risks, falls, skin concerns, or symptoms that may require referral to home health care services for skilled nursing care, wound care, occupational therapy, or respiratory therapy. ### **Supervision and signatures** Include supervisory reviews, case-manager notes, and required signatures from the participant or representative verifying services. ### **Proof of service and retention** Capture electronic visit verification when required, retain records for the payer’s timeline, and be ready to furnish documentation on request.

## **S5125 billing requirements** Align each claim with payer policy to prevent denials. ### **Units and rounding** Report S5125 in 15-minute units, totaling minutes per date of service. Apply the payer’s rounding convention and do not exceed authorized units. ### **Coverage and authorization** Attendant care coverage is often limited to specific diagnoses, settings, or hour caps. Confirm benefit criteria and obtain prior authorization when required. ### **Non-duplication with clinical visits** Do not bill S5125 at the same time as home health services that provide skilled nursing care, registered nurse or licensed practical nurse visits, certified nurse assistant visits, or therapy disciplines. ### **Setting rules** Follow payer rules on where the service can be billed. Most plans disallow S5125 in a nursing facility or intermediate care facility unless the policy specifies otherwise. ### **Clean claim essentials** Include rendering provider ID, service address, diagnosis code(s) supporting functional need, authorized units, and the correct payer program identifiers.

## **S5125 applicable modifiers** Modifier use is program-specific. Only append modifiers your payer requires. - **U1–U9**: Payer-defined tiers for acuity, program option, or self-directed care. - **HQ**: Group setting, when the plan explicitly allows shared attendant services. - **GA/GX/GZ**: Liability modifiers used when a payer designates the service as non-covered and beneficiary notification rules apply. - **93**: Synchronous telemedicine service, audio-only, if a payer uniquely permits remote check-ins for limited support tasks. Many payers require no modifier for S5125. Always follow published program guidance.

Verify active status and coverage before billing. - T1019: personal care services, per 15 minutes. - T1020: personal care services, per diem. - G0156: Services of home health aide in home health services or hospice, each 15 minutes. - S9122: home health care services; certified nurse assistant, per hour. - S5130: Homemaker service, per 15 minutes. - S5135: Companion care, per 15 minutes.
