Wiki Telephone E/M service coding

[kvought]

What do we do if a telephone e/m service is over 30 min? Are there any prolonged service codes that can be used with 99443?

I do not believe there are any prolonged codes that are accepted by insurances and 30 minutes is the maximum payable time paid for a telephone visit.

I second @nickole805 's answer. I know at some point that exact question was listed in a Medicare FAQ document and the answer was 99443 is the best you can do.
Found the reference from https://www.cms.gov/files/document/03092020-covid-19-faqs-508.pdf:
Question: How should practitioners bill for audio-only services that last longer than 30 minutes?
Answer: During the PHE for the COVID-19 pandemic, Medicare has added to the list of telehealth services CPT codes 99441–99443, which describe audio-only phone visits with practitioners who can independently bill for E/M services, and CPT codes 98966–98968, which describe audio-only phone visits with practitioners who cannot independently bill for E/M services (for example certain therapists, social workers, and clinical psychologists). CPT codes 99443 and 98968 describe 21–30 minutes of medical discussion, respectively for each practitioner type; but there are no CPT codes available to describe medical discussions lasting longer than 30 minutes.
