Medical Billing Guideline
Browse through the following billing guidelines:

Pathology Billing Guideline
Pathology billing requires accurate documentation of specimen type, test methodology, and medical necessity. Ensure proper use of CPT codes for diagnostic, molecular, and surgical pathology. Always match ICD-10 codes with ordered tests and verify payer-specific bundling rules to avoid denials.

Optometry Billing Guideline
Optometry billing must distinguish between routine vision exams and medically necessary eye care. Use correct E/M or eye exam codes, document refractive errors separately, and verify coverage for contact lens fittings. Ensure modifiers are added for bilateral procedures when required.

Ambulance Billing Guideline
Ambulance billing requires detailed trip documentation, mileage calculations, and accurate service level coding (BLS, ALS1, ALS2). Medical necessity must be clearly stated. Include time stamps, patient condition, and transport justification to ensure compliance with CMS regulations.
