CPT Code 99213

CPT Code 99213 is designated for office or other outpatient visits involving the evaluation and management of an established patient. This code is applicable when the total time spent on the encounter is between 20 and 29 minutes on the date of the encounter. It's important to note that the time includes both face-to-face and non-face-to-face activities performed by the physician or other qualified healthcare professional.

Typical Patient Description

This code is typically used for established patients presenting with a stable chronic illness or an acute uncomplicated injury. The visit often involves routine follow-up care, medication management, or preventive services.

Care Components

For a visit to qualify for CPT Code 99213, it must meet the following criteria:

  • History: An expanded problem-focused history.
  • Examination: An expanded problem-focused examination.
  • Medical Decision Making (MDM): Low complexity.

Alternatively, if more than half of the visit involves counseling or coordination of care, the visit may be reported based on time.

Time-Based Coding

When using time to select the appropriate code, the total time spent on the encounter should be documented. For CPT Code 99213, this includes:

  • Preparing to see the patient (e.g., reviewing tests)
  • Obtaining and/or reviewing separately obtained history
  • Performing a medically necessary examination and/or evaluation
  • Counseling and educating the patient/family/caregiver
  • Ordering medications, tests, or procedures
  • Referring and communicating with other healthcare professionals (when not reported separately)
  • Documenting clinical information in the electronic or other health record
  • Independently interpreting results (not reported separately) and communicating results to the patient/family/caregiver
  • Care coordination (not reported separately)

It's essential to note that time spent on activities not related to the encounter, such as travel or general teaching not specific to the patient's care, should not be included in the total time calculation.

Documentation Tips

To ensure accurate coding and reimbursement:

  • Clearly document the total time spent on the encounter.
  • Specify the time spent on counseling and coordination of care if more than half of the visit involves these activities.
  • Ensure that the documentation supports the level of service billed.
