That's it! ChatGPT now has access to all 5 FindICD10 tools.

Available Tools

Once configured, ChatGPT can use these 5 tools:

Example Conversations

Finding Codes

You: What's the ICD-10 code for type 2 diabetes with hyperglycemia?

ChatGPT: Based on my search, the ICD-10 code is:

E11.65 - Type 2 diabetes mellitus with hyperglycemia [Billable]

This code is used when the patient has elevated blood glucose levels with documented type 2 diabetes. You may also need to add:
- Z79.4 for long-term insulin use
- Z79.84 for oral antidiabetic drug use

Getting Code Details

You: Tell me about code E11.65

ChatGPT: Here are the details for E11.65 - Type 2 diabetes mellitus with hyperglycemia:

Clinical Notes:
- Use additional code to identify insulin use (Z79.4) or oral hypoglycemic use (Z79.84)

Excludes1 (cannot code together):
- Drug or chemical induced diabetes (E09.-)
- Gestational diabetes (O24.4-)
- Type 1 diabetes mellitus (E10.-)

Converting ICD-9 to ICD-10

You: What's the ICD-10 equivalent of ICD-9 code 250.00?

ChatGPT: ICD-9 code 250.00 (Diabetes mellitus without complication, type II) maps to:

E11.9 - Type 2 diabetes mellitus without complications

Note: This is an approximate mapping. The ICD-10 system is more specific, so review the documentation to ensure the most accurate code is selected.

Analyzing Clinical Notes

You: Extract ICD-10 codes from this note: "Patient presents with uncontrolled type 2 diabetes, diabetic neuropathy in both feet, and stage 3 chronic kidney disease."

ChatGPT: Based on the clinical documentation, here are the applicable ICD-10 codes:

Note: These codes should be verified against complete clinical documentation. AI analysis is suggestive, not definitive.

GPT Configuration Template

If you're creating your own Custom GPT, use these settings:

Name

ICD-10 Medical Coder by FindICD10

Description

Search 94,000+ ICD-10-CM diagnosis codes from official CMS.gov data. Get clinical notes, convert ICD-9 to ICD-10, and analyze clinical text.

Instructions

You are an ICD-10 coding assistant with access to the FindICD10 database.

When to use each tool:
- searchCodes: User describes a condition or asks "what's the code for..."
- getCodeDetails: User asks about a specific code (e.g., "tell me about E11.65")
- getRelatedCodes: User wants similar codes or to explore options
- convertCode: User mentions ICD-9 codes or asks about conversions
- analyzeClinicalNote: User provides clinical note text

Response formatting:
- Present codes as: **CODE** - Description [Billable/Category]
- Always mention billability status
- Link to findicd10.com: https://findicd10.com/codes/{CODE}

Disclaimers:
- Codes should be verified against clinical documentation
- AI analysis is suggestive, not definitive
- Coding should be done by certified professionals

Conversation Starters 1. "What is the ICD-10 code for type 2 diabetes with kidney disease?" 2. "Convert ICD-9 code 250.00 to ICD-10" 3. "Find codes for pneumonia" 4. "Analyze this clinical note for diagnosis codes"

Claude vs ChatGPT Integration

Choose Claude MCP if you're a developer using Claude Desktop or Claude Code and want local execution.

Choose ChatGPT if you prefer a web-based interface or want to share with non-technical users.

Publishing to GPT Store

To make your Custom GPT available in the GPT Store:

1. Complete your GPT configuration with name, description, and instructions
2. Add a profile picture - Use a medical/coding themed image
3. Set visibility to "Public" in the GPT settings
4. Enable "Publish to store" option
5. Submit for review - OpenAI will review before listing

Once approved, users can find your GPT by searching the GPT Store.

Rate Limits

The FindICD10 API enforces rate limits:

If you hit rate limits, the GPT will receive a 429 error and should wait before retrying.
