## 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
|
||||
$ npm run start
|
||||
|
||||
# watch mode
|
||||
$ npm run start:dev
|
||||
|
||||
# production mode
|
||||
$ npm run start:prod
|
||||
```
|
||||
|
||||
## Run tests
|
||||
|
||||
```bash
|
||||
# unit tests
|
||||
$ npm run test
|
||||
|
||||
# e2e tests
|
||||
$ npm run test:e2e
|
||||
|
||||

|
||||
$ npm run test:cov
|
||||
```
