We recently opened a new lab and would appreciate any help from other practices who own their own lab.

Our particular problem is deciding on how to bill out codes 88305 and 88342. We understand that they are billed out in units, but what if there are different diagnosis codes for each unit.

For example: 3 gastric biopsies with one showing chronic gastritis, one showing superficial antral gastritis, and one showing no findings.

Would it be.... one line item of 88305 x3 with one/all findings OR multiple line items of 88305- no findings so use procedure indication; 88305-76 for superficial antral gastritis; 88305-76 for chronic gastritis?

Any help appreciated!
