If a patient was present in our office for a problem focused exam D0140 and it is diagnosed that they have infection and need to return for an extraction or have a RCT performed in another office. They had not done either treatment and returned one month later with infection again with pain in the same tooth. What code should be used for the second visit? No treatment was able to be performed on either visit due to extensive infection and the need for antibiotic treatment prior to extraction or RCT.
Depending on the carrier you may use either D0140 again or D0170. You will need to check with the particular carrier as each have their own utilization review guidelines.
