Verity MCP Server

An MCP (Model Context Protocol) server that provides AI agents access to the Verity healthcare API for Medicare coverage policies, prior authorization requirements, and medical code lookups.

Features

• Code Lookup: Look up CPT, HCPCS, ICD-10, and NDC codes with descriptions and RVU values
• Policy Search: Search and browse Medicare LCDs, NCDs, and Articles
• Prior Auth Check: Determine if procedures require prior authorization
• Coverage Criteria: Search specific coverage criteria and requirements
• Jurisdiction Info: Get MAC jurisdiction details and covered states
• Policy Comparison: Compare coverage across different jurisdictions
• Change Tracking: Monitor policy updates and modifications

Installation

Prerequisites

• Node.js 18 or higher
• A Verity API key (get one at verity.backworkai.com)

Setup

1. Clone or download this repository:

   cd verity_mcp

2. Install dependencies:

   npm install

3. Build the server:

   npm run build

Configuration

Claude Desktop

Add the server to your Claude Desktop configuration file:

Windows: %APPDATA%\Claude\claude_desktop_config.json macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "verity": {
      "command": "node",
      "args": ["C:\\Users\\tyler\\OneDrive\\Desktop\\verity_mcp\\build\\index.js"],
      "env": {
        "VERITY_API_KEY": "vrt_live_YOUR_API_KEY_HERE"
      }
    }
  }
}

Replace YOUR_API_KEY_HERE with your actual Verity API key.

Claude Code

claude mcp add verity node C:\Users\tyler\OneDrive\Desktop\verity_mcp\build\index.js

Then set the environment variable:

set VERITY_API_KEY=vrt_live_YOUR_API_KEY_HERE

lookup_code("M54.5")           # Low back pain diagnosis

2. search_policies

Search Medicare coverage policies.

search_policies("ultrasound guidance")
search_policies("diabetes CGM")
search_policies("", { policy_type: "NCD" })  # Browse NCDs

3. get_policy

Get detailed policy information by ID.

get_policy("L33831")
get_policy("A52458", { include: "criteria,codes" })

4. compare_policies

Track policy updates over time.

get_policy_changes()
get_policy_changes({ since: "2024-01-01T00:00:00Z" })
get_policy_changes({ policy_id: "L33831" })

6. search_criteria

Search coverage criteria blocks.

search_criteria("diabetes")
search_criteria("BMI", { section: "indications" })
search_criteria("frequency", { section: "limitations" })

7. list_jurisdictions

Get MAC jurisdiction information.

list_jurisdictions()

8. check_prior_auth

Check prior authorization requirements.

check_prior_auth(["76942"])
check_prior_auth(["76942"], { state: "TX" })
check_prior_auth(["J0585"], { diagnosis_codes: ["M62.81"] })

Example Conversations

User: "Is ultrasound guidance covered for needle placement?"

Agent uses: lookup_code("76942") and search_policies("ultrasound guidance needle placement")

---

User: "What are the prior auth requirements for Botox injections in Texas?"

Agent uses: check_prior_auth(["J0585"], { state: "TX" })

---

User: "Compare coverage for CGM devices across California and Texas"

Agent uses: compare_policies(["E0787"], { jurisdictions: ["JE", "JM"] })

Troubleshooting

"VERITY_API_KEY environment variable is required"

Make sure you've set the API key in your Claude Desktop config or environment.

"API error: 401"

Your API key is invalid or expired. Check that it starts with vrt_live_ or vrt_test_.

"API error: 429"

Rate limit exceeded. Wait a moment and try again, or upgrade your API plan.
