Wiki Prolonged services

I have a provider who billed a 99358 on 1/12/21 to review a new patient chart then billed 99344 on 1/13/2021 and it was denied as "does not meet new patient requirements". Has anyone encountered this and how was your solution? Thanks for any input you can provide.

Thank you for the info, I will save this for future reference - but I am billing indirect prolonged visit for POS 12.
