CPAP Compliance Documentation: What Medicare Requires

Medicare compliance documentation isn't just administrative work. It's a clinical and legal requirement that protects your patients' coverage and your organization from audits.

Getting it right the first time saves hours of appeals.

The 90-Day Compliance Window

Requirements

For Medicare to continue covering CPAP equipment past month 3:

Usage criteria:

• Average of 4+ hours per night
• On 70% or more of nights
• Measured during a consecutive 30-day period
• Within first 90 days of use

Clinical criteria:

• Face-to-face evaluation with prescribing physician
• Physician documents continued medical need
• Documentation of benefit from therapy

Timeline

• Days 1-90: Initial rental period. Compliance data must be obtained.
• Day 91+: Continued coverage requires compliance documentation on file.
• Month 13: Rental converts to ownership. Must have met compliance at 90 days.

Required Documentation Elements

1. Compliance Data Report

Must include:

• Patient identifier
• Date range of data (consecutive 30 days within first 90)
• Device serial number or identifier
• Average usage hours per night
• Percentage of nights ≥4 hours
• Data source (AirView, Care Orchestrator, etc.)

Format:

• Manufacturer report acceptable
• Third-party compliance platform acceptable
• Manual log NOT acceptable as sole source

2. Face-to-Face Evaluation

Must document:

• Date of visit
• Patient's response to therapy
• Objective benefit (symptom improvement, partner reports, functional status)
• Continued medical necessity statement
• Physician signature and date

Timing:

• Must occur after day 31 and before day 91
• Can be in-person or telehealth (current rules)

3. Physician Order

For continued coverage:

• Signed order for continued CPAP
• Specifies device type and settings
• Dated after face-to-face evaluation

Common Documentation Failures

Failure 1: Wrong Date Range

Problem: Compliance data from days 91-120 instead of within 90-day window

Prevention: Pull data proactively at day 60-70

Failure 2: Missing Signature

Problem: Face-to-face note not signed by qualifying physician

Prevention: Verify signature before filing

Failure 3: Insufficient Detail

Problem: Note says "patient doing well" without specifics

Prevention: Use template with required elements

Failure 4: Data-Order Mismatch

Problem: Data shows compliance but order says "discontinue"

Prevention: Verify consistency before submitting

Failure 5: Wrong Data Period

Problem: Data shows 45 days average instead of consecutive 30

Prevention: Understand how to pull correct report

Documentation Best Practices

Compliance Data Pull

When to pull: Day 60-70 of therapy

Verify:

• Meets 4-hour/70% criteria
• 30 consecutive days within window
• Correct patient, correct device

If not compliant:

• Intervene before day 90
• Document intervention attempts
• Pull updated data if compliance achieved

Face-to-Face Template

Create standard note including:

> CPAP Compliance Evaluation

> Date: [date]

> Days since CPAP initiation: [number]

>

> Compliance data reviewed:

> - Date range: [dates]

> - Average usage: [X] hours/night

> - Usage ≥4 hours: [X]% of nights

> - Meets Medicare compliance: Yes/No

>

> Patient-reported response:

> - Sleep quality: [improved/unchanged/worse]

> - Daytime symptoms: [improved/unchanged/worse]

> - CPAP tolerance: [good/fair/poor]

>

> Objective findings:

> - [specific observations]

>

> Assessment: Patient meets Medicare compliance criteria. Continued CPAP therapy is medically necessary for treatment of obstructive sleep apnea.

>

> Plan: Continue CPAP therapy. Follow-up in [timeframe].

>

> [Physician signature]

> [Date]

File Organization

For each patient, maintain:

• Sleep study
• Initial order
• Delivery documentation
• Compliance data report
• Face-to-face evaluation
• Continued coverage order

Audit Response

When You Receive ADR (Additional Documentation Request)

Step 1: Note deadline (typically 45 days)

Step 2: Gather all required documents

Step 3: Review for completeness before submission

Step 4: Include cover letter summarizing contents

Step 5: Submit via required method (fax, portal, mail)

Step 6: Keep proof of submission
