What Is CPT Code 99212?
CPT Code 99212 is part of the Current Procedural Terminology (CPT) system maintained by the American Medical Association (AMA). It falls under the Evaluation and Management (E/M) category and is used to bill for established patient office visits that require a low level of medical decision-making (MDM) or problem-focused history and examination.
Key Features of CPT 99212
-
Patient Status: Only for established patients (seen within the last three years by the same provider or group).
-
Visit Complexity: Low-level medical decision-making or straightforward problems.
-
Time Requirement: Typically 10-19 minutes spent on the encounter (face-to-face and non-face-to-face time).
This code is commonly used for follow-up visits, minor illnesses, or stable chronic conditions that do not require extensive evaluation.

A problem-focused history
A problem-focused examination
Straightforward medical decision-making.”*
Documentation Requirements
To justify billing 99212, providers must document:
-
History: Brief review of the chief complaint and limited history of present illness (HPI).
-
Examination: Focused physical exam related to the problem.
-
Medical Decision-Making (MDM):
-
Number of Diagnoses or Management Options: Minimal (e.g., one stable chronic condition or acute uncomplicated illness).
-
Amount/Complexity of Data Reviewed: Minimal or none.
-
Risk of Complications: Low (e.g., rest, over-the-counter medication).
-
CPT Code 99212 Requirements
Proper documentation is critical to avoid audits and denials. Below are the minimum requirements for billing 99212:
1. History (Problem-Focused)
-
Chief Complaint (CC): Reason for the visit (e.g., “cold symptoms”).
-
History of Present Illness (HPI): 1-3 elements (e.g., duration, severity).
-
No need for Review of Systems (ROS) or Past/Family/Social History (PFSH) unless clinically relevant.
2. Examination (Problem-Focused)
-
Limited to the affected body area/system (e.g., checking throat for sore throat).
3. Medical Decision-Making (Straightforward)
| MDM Element | 99212 Requirement |
|---|---|
| Number of Diagnoses | 1 minimal problem (e.g., common cold, stable hypertension). |
| Data Reviewed | Minimal (e.g., no tests ordered, may review old records). |
| Risk Level | Low (e.g., prescribing OTC medication, minor illness). |
Providers who fail to meet these criteria may need to use a lower code (99211, often used for nurse visits) or a higher-level code (99213-99215) if more complexity is involved.
CPT Code 99212 vs. 99214: Key Differences
Many providers confuse 99212 with 99214, which is a moderate-level visit. Below is a comparison:

| Patient Status | Established | Established |
| MDM Level | Straightforward | Moderate |
| History | Problem-focused | Expanded problem-focused |
| Exam | Problem-focused | Detailed |
| Time Spent | 10-19 min | 30-39 min |
| Typical Use | Minor illness, stable condition | Chronic disease management, multiple issues |
Example Scenario:
-
99212: A patient with a mild sore throat requiring a quick exam and OTC medication recommendation.
-
99214: A diabetic patient with worsening symptoms needing lab review and medication adjustment.
