The 6 EVV Data Elements Every Home Health Agency Should Understand

Electronic Visit Verification (EVV) is governed by strict federal standards designed to eliminate billing fraud, prevent phantom visits, and verify that vulnerable patients receive authorized care. Under Section 12006 of the 21st Century Cures Act, Congress amended Section 1903(l) of the Social Security Act to require all state Medicaid programs to verify six specific data points for every in-home personal care and home health care visit.^[1][2]

Missing or inaccurate data on even one of these elements creates an immediate compliance exception, flags the visit in state aggregators like HHAeXchange, and prevents Medicaid claims from clearing pre-payment validation.^[2][3]

Here is an in-depth breakdown of the six mandatory EVV data elements, why each matters for agency reimbursement, and how modern operational workflows keep field staff compliant.

1. Type of Service Performed

The EVV record must electronically capture the specific clinical or supportive service delivered during the visit.^[1]

• Regulatory Requirement: The service logged at the point of care must correspond directly to an authorized Healthcare Common Procedure Coding System (HCPCS) code (e.g., T1000 for specialized nursing, T1002 for RN care, T1003 for LPN care, S9122 for home health aide visits, or G0151 for physical therapy).
• Billing Impact: If a caregiver is scheduled for personal care assistance but accidentally selects skilled nursing in the mobile app, the discrepancy will trigger an authorization mismatch during claim adjudication, causing an immediate denial.
• Documentation Reality: Services must align with the patient’s physician-approved Plan of Care (POC).

2. Individual Receiving the Service

The system must electronically verify the exact identity of the Medicaid recipient who received care.^[1]

• Regulatory Requirement: In Florida, this requires matching the patient's full legal name, date of birth, and unique 10-digit Florida Medicaid Recipient Identification Number.^[3]
• Common Problem: Typographical errors in recipient IDs or assigning a substitute caregiver to an unlinked patient profile are frequent causes of aggregator rejections.
• Cross-Check: The recipient recorded in the EVV visit must match the subscriber listed on the subsequent EDI 837P claim line.^[4]

3. Date of the Service

The system must establish an immutable record of the calendar date on which care was rendered.^[1]

• Regulatory Requirement: The date of service must be system-generated based on network-synchronized clock times, not manually typed or altered by the field worker.
• Overnight Shift Complexity: When a 12-hour continuous care or Private Duty Nursing shift crosses midnight (e.g., 8:00 PM to 8:00 AM), the agency management system must correctly split or allocate the visit across both calendar days to maintain EVV and payroll integrity.

4. Location of Service Delivery

The system must verify the physical location where care was provided.^[1]

• Regulatory Requirement: Electronic verification is typically achieved via GPS geofencing on a mobile device or through Interactive Voice Response (IVR) telephony placed from the patient's registered landline phone.
• Geofence Perimeter: The system captures coordinates upon clock-in and clock-out and cross-references them against the patient’s home address coordinates on file.
• Exceptions: If a caregiver takes a client to an authorized physician visit or community errand, the agency's system must support documented clinical exception overrides with supervisor sign-off.

5. Individual Providing the Service

The system must uniquely identify the employee or contractor who delivered the care.^[1]

• Regulatory Requirement: The EVV profile must correspond to an active, vetted clinician or aide. In Florida, this means the individual must have a verified Level 2 background screening eligibility determination on the AHCA Care Provider Background Screening Clearinghouse.^[5]
• Credential Safeguards: The individual’s professional licensure (RN, LPN) or training certificates (HHA 75-hour certificate, CPR/BLS, OSHA, TB test) must be current. If an expired clinician clocks in, the agency faces severe audit penalties under Florida Administrative Code Chapter 59A-8.^[6]

6. Time the Service Begins and Ends

The system must record precise, tamper-resistant timestamps for both arrival and departure.^[1]

• Regulatory Requirement: Clock-in and clock-out timestamps must be recorded contemporaneously.
• CMS Stance on Timesheets: In its official Informational Bulletin, CMS explicitly warned that retrospective web timesheets or manual self-reporting by aides does not qualify as EVV, stating that "systems that allow employees to enter their hours after the fact do not satisfy the statutory requirements of the Cures Act."^[7]
• Billing Unit Calculations: Accurate start and end times are critical because Medicaid reimburses in 15-minute increments (1 unit = 15 minutes). A 5-minute discrepancy can alter the billable units and cause claim-to-EVV reconciliation failures.

Summary of the 6 Elements

How Voice-to-Ledger Captures the Complete Visit

Capturing the six technical data elements is necessary to pass the EVV gate, but state surveyors and clinical auditors review more than just timestamps. Under Florida survey guidelines, surveyors cross-examine clinical visit documentation against EVV punches to confirm that meaningful, individualized care took place.^[8]

Bickle bridges this operational gap:

• Natural Voice Documentation: Rather than navigating dozens of mobile checklist screens, caregivers speak their clinical notes into their device at the conclusion of the visit.
• Automatic Verification: The system confirms arrival and departure within the authorized geofence, capturing the mandatory six elements cleanly.
• Structured Clinical Ledger: Spoken notes are converted into structured clinical summaries and time records that link directly to the shift, providing ironclad documentation for both Medicaid billing and AHCA survey readiness.
