Question: I have been getting denials when billing sinus x-rays to Medicare using CPT codes 70220 or 70210. What is the correct way to bill Medicare for this service?
The following diagnosis codes should be paid:
461.0 Acute maxillary sinusitis
461.1 Acute frontal sinusitis
461.2 Acute ethmoidal sinusitis
461.3 Acute sphenoidal sinusitis
461.8 Other acute sinusitis
461.9 Unspecified acute sinusitis
473.0 Chronic maxillary sinusitis
473.1 Chronic frontal sinusitis
473.2 Chronic ethmoidal sinusitis
473.3 Chronic sphenoidal sinusitis
473.8 Other chronic sinusitis
473.9 Unspecified chronic sinusitis
784.0 Headache (facial pain)
Note: Check with your local Medicare carrier for their list of appropriate and payable ICD-9 codes.
