CPT 99358 & 99359: Error Corrected

CPT 99358 & 99359: Error Corrected

With apologies for any confusion, we offer the following correction.

Our February 13 2023 article, clarifying that billing codes CPT 99358 and CPT 99359 remain payable in 2023, featured a previous version of the daisyBill video below. The original video erroneously stated that CPT 99359 is applicable to every 15-minute increment after reporting CPT 99358.

The video has been corrected to reflect that CPT 99359 is used to report each additional 30 minutes beyond the first hour. 99359 may also be used to report the final 15 to 30 minutes of prolonged service on a given date.

Both CPT codes remain payable, as originally stated.

(Updated) Video: CPT 99358 & 99359 in 2023

A February 15, 2023 update to the Official Medical Fee Schedule (OMFS) changed the Status Code of two commonly billed non-face-to-face service CPT codes, CPT 99358 and CPT 99359.

Despite changing the assigned status codes, both procedures remain payable under the OMFS.

The brief video below breaks down precisely what the Status Code changes for CPT 99358 and 99359 mean and why both codes continue to be reimbursable from February 15, 2023, when the updates to California’s Physician Fee Schedule took effect.
