Originally they used Z71.9 unspecified. It was a charged as a second OV with the well visit as the doctor was charging for immunization counseling. I believe the insurance denied for Z71.9 as inappropriate primary dx codeZ71.9 is for 'unspecified counseling' which would indicate that there was no documentation about what the counseling was about. If the records shows that counseling was regarding immunizations, then Z71.89 - other specified counseling - would be more accurate. However, that may or may not resolve the problem - what CPT code was billed and what was the reason given for the rejection or denial of the claim? It's also quite possible that the insurance may just not cover this.
An office visit code would be inappropriate as those are for problem-oriented visits and require a chief complaint so it would be no surprise to see that deny with Z71.9.Originally they used Z71.9 unspecified.
