Medicare-certified home health agencies are routinely subject to medical review through Additional Documentation Requests (ADRs) issued by Medicare Administrative Contractors (MACs). One of the primary MACs conducting these reviews is Noridian Healthcare Solutions, operating under the oversight of the Centers for Medicare & Medicaid Services (CMS).
A Noridian ADR is a formal audit event requiring agencies to submit complete medical records to support claims that have already been paid. The burden of proof lies entirely with the agency. If documentation is incomplete, inconsistent, or fails to demonstrate eligibility and medical necessity, claims are subject to denial and recoupment.
What Is a Noridian ADR?
Noridian ADRs are issued under multiple review programs, including Targeted Probe and Educate (TPE) and post-payment medical review. These requests are typically triggered by billing patterns, utilization trends, or prior denial history.
Unlike surveys, ADRs are claim-specific reviews. Each selected episode must independently meet Medicare requirements.
When an ADR is issued, it will include:
Beneficiary information and dates of service
Specific documentation requirements
Submission deadline
Instructions for record submission
Failure to respond within the timeframe results in automatic denial.
Scope of Home Health Record Review
Noridian evaluates whether the home health episode meets Medicare coverage requirements under 42 CFR §484 and CMS policy guidance. The review focuses on eligibility, physician involvement, and documentation consistency.
The core question is: Was the patient eligible for home health services, and was care medically necessary throughout the episode?
Key areas of review include:
Homebound status
Need for skilled services
Physician certification and oversight
Plan of care compliance
Visit documentation
Ongoing medical necessity
Core Documentation Required
Certification and Plan of Care (POC)
The certification and plan of care are foundational documents in any ADR review. They must demonstrate physician involvement and establish the framework for services.
Documentation must include:
Late or missing signatures are a common cause of denial.
Face-to-Face Encounter (F2F)
The face-to-face encounter is a high-risk area in home health audits. It must clearly connect the patient’s condition to the need for home health services.
To be compliant, it must:
Occur within the required timeframe
Be performed by a qualified practitioner
Include clinical findings (not just diagnoses)
Support:
Be signed and dated
Generic or templated F2F documentation frequently results in denial.
Homebound Status Documentation
Homebound status must be clearly supported in the clinical record. It is not sufficient to state that the patient is homebound.
Documentation must show:
This must be supported consistently across all disciplines.
Skilled Need and Medical Necessity
The record must clearly demonstrate that the patient requires skilled services that cannot be provided by non-skilled personnel.
Documentation should reflect:
If care appears routine or custodial, claims are at high risk for denial.
Visit Documentation (Clinical Notes)
Visit notes must demonstrate the delivery of skilled services and ongoing medical necessity.
Strong documentation includes:
Detailed interventions
Patient response to care
Changes in condition
Clinical decision-making
Notes must be individualized and consistent across disciplines.
OASIS and Assessment Data
OASIS assessments must align with the clinical record and accurately reflect the patient’s condition.
Agencies must ensure:
OASIS data is accurate and complete
Functional limitations are supported in documentation
Coding aligns with diagnoses and services
Inconsistencies between OASIS and clinical notes are frequently cited.
Common Denial Drivers
Noridian ADR reviews often identify recurring documentation issues that lead to claim denials.
Common denial reasons include:
Face-to-face documentation lacking clinical support
Weak or unsupported homebound status
Insufficient documentation of skilled need
Missing or late physician signatures
Inconsistent documentation across disciplines
Generic or templated clinical notes
Even a single deficiency can result in denial of the entire episode.
High-Risk Home Health Scenarios
Certain cases are more likely to be selected for ADR review.
High-risk scenarios include:
Therapy-only cases without nursing involvement
Long episodes with minimal documented progress
Diagnoses that do not clearly support skilled need
Repetitive or cloned documentation
High utilization patterns
Agencies should monitor these cases closely.
How to Respond to a Noridian ADR
A structured and disciplined response is critical. The goal is to present a clear, defensible clinical story.
Step-by-Step Response Approach
Review ADR immediately and confirm deadline
Identify all required documentation
Assign responsibility for chart review
Conduct internal audit of the record
Verify:
Organize records chronologically
Best Practices for Submission
Well-organized submissions significantly improve audit outcomes.
Agencies should:
Submit a complete medical record
Include a clinical summary explaining eligibility
Highlight key documentation supporting:
Homebound status
Skilled need
Ensure consistency across all documentation
Confirm all required signatures and dates
Clear presentation helps reviewers understand the case.
Strategies to Reduce ADR Risk
Agencies must implement proactive systems to reduce future audit exposure.
Effective strategies include:
Conduct routine internal chart audits
Strengthen physician documentation and F2F processes
Train clinicians on Medicare requirements
Align OASIS data with clinical documentation
Monitor high-risk cases
Perform mock ADR reviews
Strong internal controls reduce denial rates.
Alignment with CMS Home Health Requirements
Noridian reviews are based on CMS Conditions of Participation and Medicare policy. Agencies must ensure documentation aligns with these standards.
Strong-performing agencies demonstrate:
Clear and consistent documentation
Strong physician involvement
Accurate and timely records
Effective quality assurance programs
Alignment with 42 CFR §484 requirements
Conclusion
Noridian home health ADRs require agencies to fully support eligibility, medical necessity, and compliance with Medicare requirements. The highest-risk areas include face-to-face documentation, homebound status, and skilled need.
Agencies that implement strong documentation systems, conduct proactive audits, and develop structured ADR response processes are best positioned to reduce denials and maintain compliance.
