What's inside

Diagnosis codes

• Don't include patient names or other identifiers in your questions. EyeCode needs only the clinical terms. We count calls per hashed IP address and don't store question text.
• Answers are reference data from public CMS files, not billing or legal advice. Your MAC has the final word.
