> Look up Vietnamese ICD-10 medical diagnostic and procedure codes with detailed information, or browse the complete hierarchy of all available codes in the system. Quickly find the specific clinical codes you need for medical records, billing, or healthcare documentation.

**Category:** Healthcare | **Website:** [icd.kcb.vn/](https://icd.kcb.vn/) | **Docs:** [parse.bot/marketplace/78778160-a7cc-4700-813b-23ae3a9ae9d4/icd-kcb-vn-api](https://parse.bot/marketplace/78778160-a7cc-4700-813b-23ae3a9ae9d4/icd-kcb-vn-api)

Pay-per-use API proxy for Locus Pro. Each call burns credits from your workspace balance.

## Access

**Base URL:** `https://api.paywithlocus.com/api/wrapped/credits/icd-kcb/`
**Auth:** `Authorization: Bearer <LOCUS_CREDITS_SECRET_KEY>` (an `lcr_` secret key or a scoped `lcac_` agent credential)
**Required header:** `Idempotency-Key: <fresh UUID per call>`. A retry with the same key replays the stored result without a new charge.
**Response:** the provider response after any endpoint-specific normalization. `X-Locus-Credits-Charged` carries the charge and `X-Locus-Credits-Balance` the remaining balance. Insufficient credits return `402` before the provider is called.
**Pricing:** estimated costs below are USD. Locus debits the credit equivalent at your workspace rate.

> Using a Pay With Locus wallet key (`claw_` prefix)? Wallet routes are documented separately: https://docs.paywithlocus.com/wrapped-apis/for-agents

## Endpoints

### Query all code

Retrieve a list of ICD-10 codes from the classification tree. By default returns 3-character category codes. Set include_subcategories to true to also retrieve 4-character subcategory codes (significantly slower). Use limit_chapters to restrict traversal scope.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `include_subcategories` | boolean | No | When true, also fetches 4-character subcategory codes under each 3-character category. Significantly increases response time. |
| `limit_chapters` | integer | No | Limit traversal to first N chapters (1-22). Omitting returns all 22 chapters. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/icd-kcb/query-all-code \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"include_subcategories":"<boolean>","limit_chapters":"<integer>"}'
```

### Query code

Get detailed information for a specific ICD-10 code, including disease name, description, and classification hierarchy (chapter, section, parent group). Returns Vietnamese-language disease data. Returns stale_input when the code is not found in the database.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `code` | string | Yes | ICD-10 code to look up (e.g. 'K35.8', 'A00.0', 'J18.9'). Supports both 3-character categories and 4-character subcategories with or without dots. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/icd-kcb/query-code \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"code":"<string>"}'
```
