I have been thought previously, (example) when an excision of RT shoulder mass comes back from pathology as lipoma to bill 23075, and if it's cyst or lesion to bill 11402. Now when I change the code from 11402 to 23075 (procedure done in office) MA's disagree stating that CPT codes 2XXXX like 23075 are only for OR procedures. That if done in the office 114XX CPT codes should be used. I am getting vey confused now on billing mass excisions for OV vs OR procedures. Can anyone please clarify if this is correct? We even had a scenario when I changed the code from 114XX to 2XXXX because it came back as lipoma, the insurance applied higher copay/deductible to patient and they all stated I coded it wrong. Please help me understand this. Am I wrong?
