CPT Code 99213 Description
CPT Code 99213 is an Evaluation and Management (E/M) code used for office or other outpatient visits requiring a low to moderate level of medical decision-making (MDM) or 15-29 minutes of total time spent on the encounter. This code falls under the established patient category, meaning the patient has been seen by the provider or another provider in the same specialty within the same group within the past three years.
Key Components of CPT 99213
To bill 99213, providers must meet two of the following three key components:
-
Expanded Problem-Focused History – A brief history of present illness (HPI) with a limited review of systems (ROS) and past, family, and social history (PFSH) if relevant.
-
Expanded Problem-Focused Examination – A limited examination of the affected body area or organ system.
-
Low to Moderate Complexity Medical Decision-Making (MDM) – This involves:
-
Number and Complexity of Problems Addressed (e.g., stable chronic illness, acute uncomplicated illness).
-
Amount and/or Complexity of Data Reviewed (e.g., lab tests, imaging).
-
Risk of Complications and/or Morbidity (e.g., prescription drug management, minor procedures).
-
Alternatively, providers can use time-based billing if they spend 15-29 minutes on the encounter, including:
-
Preparing for the visit
-
Reviewing records
-
Ordering tests
-
Counseling the patient

Documenting the visit

CPT Code 99213 Meaning
CPT 99213 is part of the E/M coding system developed by the American Medical Association (AMA). The structure of the code breaks down as follows:
-
“992” – Indicates an office or outpatient visit.
-
“13” – Represents the level of service (1 = lowest, 5 = highest).
Comparison with Other E/M Codes
| CPT Code | Level of Service | MDM Complexity | Time (Minutes) |
|---|---|---|---|
| 99211 | Minimal (nurse visit) | Straightforward | 5-10 |
| 99212 | Problem-Focused | Straightforward to Low | 10-19 |
| 99213 | Expanded Problem-Focused | Low to Moderate | 15-29 |
| 99214 | Detailed | Moderate | 30-39 |
| 99215 | Comprehensive | High | 40-54 |
This table shows that 99213 is a mid-level E/M code, suitable for cases requiring more than a simple check-up but not extensive workup.
CPT Code 99213 Age Restriction
There are no specific age restrictions for CPT 99213. It can be used for:

-
Adults (e.g., hypertension management, diabetes check-ups).
-
Geriatric patients (e.g., arthritis follow-ups, medication management).

-
A 65-year-old with stable hypertension may also qualify if the provider adjusts medications and reviews lab results.
