A progressive Node.js framework for building efficient and scalable server-side applications.
## Description
Claim Guard Backend - A NestJS application for managing ICD-9 and ICD-10 medical codes with Excel import functionality.
## Features
- **ICD Code Management**: Import and manage ICD-9 and ICD-10 medical codes
- **Excel Import**: Read data from Excel files and store in PostgreSQL database
- **Search & Filter**: Search codes by category, code, or display text
- **REST API**: Full REST API endpoints for accessing ICD data
- **Pagination**: Built-in pagination support for large datasets
## ICD Service Endpoints
### Import Data
```bash
POST /icd/import
```
Imports ICD-9 and ICD-10 data from Excel files in the `test/` directory.
### Search Codes
```bash
GET /icd/search?category=ICD10&search=diabetes&page=1&limit=10
```
Search ICD codes with optional filters:
- `category`: Filter by ICD9 or ICD10
- `search`: Search in code or display text
- `page`: Page number (default: 1)
- `limit`: Items per page (default: 10)
### Get Statistics
```bash
GET /icd/statistics
```
Returns count statistics for ICD codes.
## Database Schema
The application uses PostgreSQL with Prisma ORM. The ICD codes are stored in the `icd_codes` table with the following structure:
```sql
CREATE TABLE "icd_codes" (
"id" TEXT PRIMARY KEY DEFAULT gen_random_uuid(),
"code" TEXT UNIQUE NOT NULL,
"display" TEXT NOT NULL,
"version" TEXT NOT NULL,
"category" TEXT NOT NULL, -- "ICD9" or "ICD10"
"createdAt" TIMESTAMP DEFAULT NOW(),
"updatedAt" TIMESTAMP DEFAULT NOW()
);
```
**ID Format**: The `id` field now uses UUID (Universal Unique Identifier) format like `550e8400-e29b-41d4-a716-446655440000` instead of CUID.
## Setup Instructions
1. **Install Dependencies**
```bash
npm install
```
2. **Database Setup**
Create a `.env` file with your PostgreSQL connection:
```bash
DATABASE_URL="postgresql://username:password@localhost:5432/claim_guard_db?schema=public"
```
3. **Generate Prisma Client**
```bash
npx prisma generate
```
4. **Run Database Migrations**
```bash
npx prisma db push
```
5. **Place Excel Files**
Ensure the following files are in the `test/` directory:
- `[PUBLIC] ICD-9CM e-klaim.xlsx`
- `[PUBLIC] ICD-10 e-klaim.xlsx`
The Excel files should have at least 3 columns:
- Column 1: Code
- Column 2: Display/Description
- Column 3: Version
## Project setup
```bash
$ npm install
```
## Compile and run the project
```bash
# development
