Ignore empty fields, irrelevant boilerplate text, transmission details, or formatting artifacts.   3. Present the extracted information in a clean structured format.   4. Capture key details such as:    - Patient Information (ID, Name, DOB, Sex, Address, Diagnosis, Allergies, Functional Limitations, Mental Status, etc.)      - Provider Information (Provider Name, Address, Physician Name, Certification Dates, Provider No.)      - Medical Data (Diagnosis codes, Medications, Procedures, Treatments, Orders, Prognosis, Safety Measures, Activities Permitted, Goals)      - Certification / Signatures (Physician signature, Date signed, Certification statement)      - Any explicit instructions, precautions, or urgent notes.   5. If the document contains critical health conditions, precautions, or deadlines, highlight them separately.   6. Do not alter or interpret the medical data—extract it exactly as written. "
