# Welcome to Medera Medical Coding
> ICD-10, CPT, HCPCS, SNOMED CT, LOINC, RxNorm calibrated for behavioral health.
Medera Medical Coding generates accurate, defensible codes from clinical context — every code anchored to a quoted note span and reported with calibrated confidence. The engine is **behavioral-health-aware** — F-code specificity, BH-relevant CPT and E\&M, psychotropic RxNorm — but supports the full coding surface for primary care overlap.
Every code returned by the Medera API includes the documentation span that supports it. Suggestions never auto-post — the coder or clinician confirms.
## Supported code systems
US diagnosis
US inpatient procedure
WHO international
Outpatient procedure / E\&M
Non-physician services
Clinical terminology
Lab + instrument observations
Psychotropic + general medication
## Endpoints
| Endpoint | Surface | Purpose |
| :---------------------------------------------- | :---------- | :---------------------------------------------------------- |
| `POST /api/therapy/suggest-codes` | AI Services | Standalone suggestion from diagnosis + procedure text |
| `POST /api/pa/coding-suggest` | AI Services | Real-time detection during intake — flags PA-required codes |
| `POST /api/therapy/generate-soap-note-enhanced` | AI Services | SOAP with `include_billing_codes: true` |
## Use cases
Assign accurate diagnosis and procedure codes to behavioral-health encounters using documentation-anchored suggestions.
Surface missing specificity, severity qualifiers, and gaps as clinical queries before sign-off.
Sweep panels for missed codes, run retrospective audits, resubmit cleanly.
