Codes 99358 and 99359 are used for non-face-to-face prolonged services by the billing physician/NP/PA when provided in relation to an E/M service on the same or different day as an E/M service. If the clinician meets half of the threshold time for the prolonged service without face-to-face contact (31 minutes), use 99358.
And the best part of this announcement: CMS will pay using CPT® codes 99358 & 99359, not HCPCS codes, and follow CPT® coding rules.
