Complete guide to viewing and searching CMS Medicare Coverage data including National Coverage Determinations (NCDs), Local Coverage Determinations (LCDs), and Billing & Coding Articles.

Overview¶

The Medicare Coverage Data Viewer provides access to CMS coverage policies that determine what Medicare will pay for. These documents provide critical guidance for billing and coding decisions.

Access: Navigate to Coverage Policies → NCD / LCD from the dashboard sidebar.

Data Coverage: - NCDs - National Coverage Determinations (CMS-wide policies) - LCDs - Local Coverage Determinations (regional MAC policies) - Articles - Billing & Coding guidance documents

Understanding Coverage Data¶

National Coverage Determinations (NCDs)¶

NCDs are national policy decisions by CMS that apply consistently across all Medicare Administrative Contractors (MACs). They determine:

• Whether a specific item or service is covered
• Under what conditions coverage applies
• Any specific coding or documentation requirements

Key Fields: | Field | Description | |-------|-------------| | Section | NCD manual section number (e.g., 20.9.1) | | Title | Full title of the NCD | | Effective Date | When the NCD became/becomes effective | | Version | Version number of this NCD |

Local Coverage Determinations (LCDs)¶

LCDs are regional policies issued by MACs that apply only within their jurisdictions. They provide:

• Coverage criteria specific to a geographic area
• Coding guidance and limitations
• Documentation requirements for specific services

Key Fields: | Field | Description | |-------|-------------| | Display ID | LCD identifier (e.g., L35014) | | Title | Full title of the LCD | | Status | Current status (Future, Proposed, Current, Expired, Retired) | | Contractor | MAC that issued the LCD | | Effective Dates | Original and revision effective dates |

Billing & Coding Articles¶

Articles are companion documents to LCDs that provide:

• Detailed coding guidance
• ICD-10 code lists for covered diagnoses
• HCPCS code coverage information
• Documentation requirements

Key Fields: | Field | Description | |-------|-------------| | Display ID | Article identifier (e.g., A57704) | | Title | Full title of the article | | Status | Current status | | Article Type | Type of article content | | Related LCD | Associated LCD, if any |

3. Compare Regional Policies¶

Scenario: Understand coverage differences across MACs

Steps: 1. Search for LCDs by service name 2. Note which contractors have policies 3. Compare coverage criteria between MACs 4. Identify variations in coding requirements

4. Track Policy Changes¶

Scenario: Monitor updates to coverage policies

Steps: 1. Navigate to the LCD or NCD 2. Click View to open the document 3. Review Revision History section 4. Note effective dates for changes

Troubleshooting¶

No Results Found¶

Possible causes: 1. Search term too specific 2. Document uses different terminology 3. Policy doesn't exist for the service

Solutions: - Try broader search terms - Search by code instead of name - Check CMS website for latest data

Document Won't Load¶

Possible causes: 1. HTML file not yet generated 2. Data not loaded

Solutions: - Contact administrator to verify data is loaded - Try refreshing the page - Check if the document exists in search results

Links Not Working¶

Possible causes: 1. External CMS links may be outdated 2. Internal anchors may not match

Solutions: - External links open in new tabs by design - Use table of contents for navigation - Search for updated document versions

Best Practices¶

✅ DO:¶

• Start with LCDs for regional coverage - they're most commonly referenced
• Check NCDs when LCD references national policy
• Review revision history to understand policy changes
• Verify effective dates before applying coverage criteria
• Cross-reference LCDs with related Articles for complete guidance

❌ DON'T:¶

• Assume coverage without reading the full document
• Use retired policies for current billing decisions
• Ignore contractor differences across regions
• Skip documentation requirements listed in policies
