Wiki Billing HME and PAP on separate dates

[mgarcia400]

A patient came in for her annual preventative visit on one date at her PCP. The visit was billed with appropriate cpt 99396 paired with dx code Z00.00. A PAP was not performed on this date of service. She comes back to PCP three days later to have preventative PAP performed with dx code Z01.419. This visit was billed as 99213 and denied from insurance as inappropriate coding. Can anyone clarify how this should have been billed correctly?

Thank you

For the second visit, what was performed that would justify 99213?? If the patient presented just for PAP (likely no exam since comprehensive exam for preventative visit 3 days prior), I would just bill Q0091 for the PAP collection. If the patient has Medicare (or another insurance that covers it), and there was also a pelvic and breast exam that was not done 3 days prior, then G1010 would also be appropriate.
Just out of curiosity - why was the PAP not taken at the first visit?
