CPT 99417: Prolonged Office Visit Add-On Code Explained

Jupiter RCM article cover: CPT 99417: Prolonged Office Visit Add-On Code Explained

CPT 99417 is the add-on code for prolonged office or outpatient visits. It is reported for each full 15 minutes of total time beyond the time required for 99205 or 99215, when the visit level was chosen by time. Medicare does not accept 99417 and uses HCPCS code G2212 instead, with different thresholds.

CPT 99417 description

99417 is a prolonged outpatient evaluation and management service, each 15 minutes of total time beyond the required time of the primary service. For office visits, it is added to 99205 (new patient) or 99215 (established patient), and only when the primary code was selected by time, not by medical decision making.

When 99417 starts: CPT vs. Medicare

Total time on the date of the visitMost commercial payers (CPT)Medicare
Established patient99215 at 40–54 min; 99215 + 99417 ×1 at 55–69 min; ×2 at 70–84 min99215 at 40–68 min; 99215 + G2212 ×1 at 69–83 min; ×2 at 84–98 min
New patient99205 at 60–74 min; 99205 + 99417 ×1 at 75–89 min; ×2 at 90–104 min99205 at 60–88 min; 99205 + G2212 ×1 at 89–103 min; ×2 at 104–118 min

Medicare thresholds are from the CMS Evaluation and Management Services guide (MLN006764) (opens in a new tab). The difference exists because Medicare counts prolonged time from the end of the old 99205 and 99215 time ranges rather than from their minimums.

What counts toward the time

The same total time as the primary visit: the practitioner’s time on the date of the visit, face-to-face or not, including:

  • Preparing to see the patient, such as reviewing tests
  • Getting or reviewing separately obtained history
  • Performing a medically appropriate exam
  • Counseling and educating the patient, family or caregiver
  • Ordering medications, tests or procedures
  • Referring and communicating with other professionals (when not separately reported)
  • Documenting in the record
  • Independently interpreting results (when not separately reported) and coordinating care

Clinical staff time and time on other days do not count.

Common 99417 mistakes

  • Billing it to Medicare: use G2212 for Medicare patients.
  • Adding it to 99214 or 99204: it only follows the highest level, 99215 or 99205.
  • Choosing the level by MDM: 99417 requires the primary code to be chosen by time.
  • Partial units: report it only for each full 15 minutes.
  • No time in the note: document the total minutes, and ideally what filled them.
