This article covers:
There are two time-based CPT® codes for non-face-to-face prolonged care services. These codes may not be used on the day of an Evaluation and Management (E/M) service, such as an office visit or hospital service. Physicians and other qualified health care professionals who have evaluation and management (E/M) in their scope of practice may use these codes. The Center for Medicare and Medicaid Services (CMS) has assigned a status indicator of invalid to these codes, and stopped paying for them as of 1/1/2023.
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 a different day than an E/M service. CPT® says it “may only be reported when it occurs on a date other than the date of an evaluation and management service.” Their emphasis.
| Code | Description |
| 99358 | Prolonged evaluation and management service before and/or after direct patient care, first hour |
| 99359 | each additional 30 minutes (List separately in addition to code for prolonged services) |
