# CIM-10-FR

> French modification of ICD-10 (CIM-10-FR). The standard for diagnosis coding in France

The French modification of ICD-10, maintained by the ATIH. Required for diagnosis coding across French hospitals and the basis for PMSI reporting and T2A reimbursement. Around 16,000 alphanumeric codes (3–5 characters, e.g., `E11.9`).

## Quick start

System identifiers: `cim10fr-inpatient` · `cim10fr-outpatient`

## Encounter type

<Warning>
  **Encounter type is required.** CIM-10-FR coding guidelines differ significantly between inpatient and outpatient settings. For instance, in the outpatient setting, one should only code established diagnoses. In the inpatient setting, one should also include all diagnoses that are uncertain, even those that are ruled out. Use `cim10fr-inpatient` for inpatient cases and `cim10fr-outpatient` for outpatient cases. The correct guideline set is applied automatically based on the suffix.
</Warning>

## Inpatient procedures

<Tip>
  For French inpatient PMSI episodes, CIM-10-FR is paired with [CCAM](/coding/ccam) for procedure coding. Use `cim10fr-inpatient` for diagnoses and `ccam` for procedures in the same request.
