2. Executive Summary & Scope

2.1 Operational Boundaries

This Standard Operating Procedure (SOP) defines the mandatory lifecycle for structuring, calculating, verifying, and posting Home Nursing Services Charges within the enterprise billing infrastructure. It governs all in-home clinical care episodes, including skilled nursing visits, continuous infusion therapy, wound management, post-operative assessments, and geriatric chronic disease monitoring.

2.2 Regulatory Standards & Compliance

All financial and clinical documentation must strictly comply with:

• Centers for Medicare & Medicaid Services (CMS) Home Health Prospective Payment System (HH PPS) guidelines.
• Health Insurance Portability and Accountability Act (HIPAA) Title II privacy and electronic transaction standards.
• State Board of Nursing scope-of-practice regulations regarding visit duration and acuity coding.
• Generally Accepted Accounting Principles (GAAP) concerning revenue recognition and unbilled accounts receivable (AR).

3. Prerequisites & Tool Requirements

3.1 Software & System Access

• Electronic Health Record (EHR): Enterprise EHR (e.g., Epic Home Health, Cerner, or Kinnser/WellSky) with active clinical documentation modules.
• Practice Management / Billing System: Enterprise Revenue Cycle Management (RCM) platform configured with current HCPCS/CPT codes and payer fee schedules.
• Geospatial & Mileage Verification Tool: Integrated GPS timestamping and routing software (e.g., Alayacare or HHAExchange) to validate visit duration and travel distance.

3.2 Equipment & Safety PPE

• Encrypted, mobile-MDM managed tablet or ruggedized laptop equipped with multi-factor authentication (MFA) tokens.
• Universal Precautions Personal Protective Equipment (PPE) compliant with OSHA standards (for physical audits or concurrent ride-alongs).

4. Roles & Responsibilities (RACI Matrix Table)

• Responsible (R): The role that performs the activity.
• Accountable (A): The sole role with final approval and fiduciary ownership.
• Consulted (C): The role providing advisory input or compliance validation.
• Informed (I): The role updated on operational status and exception outcomes.

5. Step-by-Step Operational Procedure

Phase 1: Intake, Authorization, and Fee Schedule Mapping

• 1.1 Receive and review the primary physician’s signed Plan of Care (POC) and medical necessity documentation within the EHR intake module.
• 1.2 Verify active insurance eligibility, prior authorization limits, and specific contracted or statutory fee schedules (CMS, private payer, managed care) via the RCM clearinghouse portal.
• 1.3 Assign baseline HCPCS and CPT charge codes to the patient profile matching the authorized visit types (e.g., G0299 for RN services, G0300 for LPN services, S9123 for therapeutic nursing per hour).
• 1.4 Validate that the patient’s financial responsibility (copay, coinsurance, or deductible terms) is documented and signed within the Conditions of Admission and Financial Agreement.

Phase 2: Visit Execution and Electronic Data Capture

• 2.1 The Field Clinician logs into the mobile EHR application at the point of care, utilizing GPS timestamping to record arrival coordinates and exact entry time.
• 2.2 Execute clinical assessments, interventions, and patient education in strict accordance with the POC.
• 2.3 Document all delivered care elements, vital signs, clinical notes, and exact departure timestamp within the EHR before leaving the premises.
• 2.4 Synchronize mobile clinical records to the enterprise database, triggering the automated electronic visit verification (EVV) compliance ledger.

Phase 3: Charge Capture, Reconciliation, and Auditing

• 3.1 The Clinical Billing Specialist runs the daily automated charge generation interface between the EHR and the RCM billing engine.
• 3.2 Cross-reference generated charges against EVV logs to verify that documented visit durations match billed time units within allowable variance thresholds ($\pm 5$ minutes).
• 3.3 Audit high-acuity add-on codes, supplies, and mileage charges against itemized clinical documentation receipts and authorized POC limits.
• 3.4 Resolve any flagged discrepancies (e.g., missing clinical notes, unverified visit times) by issuing automated task tickets to the respective Field Clinician.

Phase 4: Claims Generation, Submission, and Posting

• 4.1 Perform final pre-bill scrub in the RCM system to catch common coding errors, NPI mismatches, and invalid diagnostic pointers.
• 4.2 Generate and electronically submit clean claims (CMS-1500 or UB-04 format depending on regulatory classification) to the primary payer clearinghouse.
• 4.3 Post remittance advice (835 Electronic Remittance Advice) upon payer adjudication, reconciling collected amounts against established charge structures.
• 4.4 Route any denied or rejected claims to the exception management workflow for secondary review and resubmission.

6. Quality Assurance & Verification Criteria

6.1 Audit Checklist

• EVV Synchronization Rate: $\ge 98%$ of all home visits must feature automated GPS and timestamp verification matched to billing records.
• Documentation-to-Billing Lag: Clinical notes must be completed, signed, and locked in the EHR within 24 hours of visit completion.
• Coding Accuracy: Quarterly random sampling of 50 patient charts to verify exact correspondence between POC orders, clinical charting, and billed HCPCS/CPT codes.

6.2 Tolerance Thresholds & Acceptance Benchmarks

• Financial Variance: Discrepancies between calculated charges and contractual payer allowable rates must not exceed $$0.00$ for fixed-fee schedules and $\pm 0.5%$ for tiered hourly rates.
• Clean Claim Rate: First-pass clean claim submission rate must meet or exceed 95%.
• Unbilled AR Aging: Total unbilled accounts receivable due to missing clinical notes or charge validation failures must not exceed 4 days of average daily revenue (ADR).

7. Practical Troubleshooting Scenarios

Scenario A: EVV Timestamp Discrepancy / Missing Check-Out

• Trigger: The Field Clinician forgets to log their departure on the mobile app, resulting in an unverified open visit status and suspended charge generation in the RCM system.
• Immediate Corrective Action Protocol:
  1. The billing system flags the record as an "Unverified Visit Exception" within 12 hours.
  2. The Clinical Billing Specialist contacts the Field Clinician and Clinical Supervisor via secure communication channels.
  3. The clinician submits a formal, signed Manual Time Verification Attestation Form, supported by secondary audit trails (e.g., synchronous telehealth check-ins, contemporaneous charting timestamps, or family/patient verbal confirmation logs).
  4. The Clinical Supervisor reviews and approves the attestation in the EHR administrative portal.
  5. The billing specialist manually overrides the EVV flag, attaches the verification form as a system audit attachment, and releases the charge into the active billing cycle.

Scenario B: Payer Authorization Exhaustion Mid-Episode

• Trigger: A patient requires extended skilled nursing visits beyond the pre-authorized limit, causing the RCM system to place subsequent charges on administrative hold.
• Immediate Corrective Action Protocol:
  1. The RCM system generates a "Payer Authorization Exhausted" alert, routing the account to the Patient Access / Intake Coordinator and Revenue Cycle Manager.
  2. The Field Clinician submits an urgent updated clinical summary and request for continued care (RFC) to the physician for re-certification.
  3. The Intake Coordinator submits the expedited re-authorization request to the payer utilization management department within 4 business hours.
  4. Interim Financial Handling: Care delivery must not be abruptly terminated (to prevent patient abandonment liabilities). Charges incurred during the retroactive review window are segregated into a provisional "At-Risk / Pending Retro-Auth" general ledger account.
  5. Upon payer determination, if authorized, charges are moved to standard AR; if denied, the balance is routed for internal write-off review or financial hardship evaluation per institutional charity care policies.
