Medical coding translates healthcare services, diagnoses, and procedures into standardized alphanumeric codes for billing and data tracking.
🔹 How It Works
- Provider Documentation → Clinicians record patient visits
- Coder Analysis → Assigns:
- CPT®/HCPCS (procedures)
- ICD-10-CM (diagnoses)
- Modifiers (service specifics)
- Claim Generation → Codes populate billing forms
