icd10_code validator
ICD-10-CM `A00` or `A00.0` format, with resolver fallback.
Reference
Format
Matches `/^[A-Z]\d{2}(\.\d{1,3})?$/` after uppercasing. One uppercase letter, two digits, optional dot + 1–3 more digits.
Examples
- E11.9 (Type 2 diabetes without complications)
- I10 (Essential hypertension)
- "asthma" → resolved to J45.909
How it runs
Implementation
Faithful summary of lib/validators.ts. Validators are pure functions and run identically in the worker, the Workbench, and the MCP server.
function validIcd10(value) {
return /^[A-Z]\d{2}(\.\d{1,3})?$/.test(value.toUpperCase())
? OK
: fail('icd10_format', 'expected A00 or A00.0')
}
// Plus the resolver wrapper.Config
Use in a template
Validators attach to a field on a custom template. The cascade runs them after mapping but before commit; failures surface in the per-row validation report.
fields:
- column: icd10_code
type: string

Common gotchas
- We accept ICD-10-CM (US/CH variant). WHO ICD-10 codes that overlap will pass; codes that are CM-only (e.g. `O80`) and codes that are WHO-only behave differently downstream.
- Decimal point is optional, but a trailing dot with no digits (`I10.`) is rejected. The regex requires 1–3 digits after the dot when the dot is present.
- Lowercase input is uppercased before matching. `e11.9` passes.

Pricing
Validators run on every committed row
Validators add no AI cost — they are pure functions. Every map bills a small flat per-map fee from your prepaid token wallet ($10 minimum, shared across our suite); only columns that reach the metered LLM layer, plus any-to-any convert and reshape, bill real AI tokens. See pricing →
