CPT Code 99213 Explained: Documentation, Billing Guidelines & Reimbursement Tips

Have you ever thought about how healthcare providers choose the right billing code for a standard office visit and ensure it is properly documented and reimbursed?

While it might appear simple, the process requires evaluating the patient’s medical history, the level of visit complexity, and the time spent during the appointment. Among these, CPT 99213 is one of the most frequently used evaluation and management (E/M) codes for established patients. A clear understanding of this code is essential for reducing claim denials, lowering audit risks, and maximizing revenue.

This detailed guide will break down CPT 99213, covering its documentation requirements, billing rules, and effective reimbursement practices.

Overview of CPT 99213

CPT 99213 is an evaluation and management (E/M) code used for office or outpatient visits with established patients. It applies when the provider performs low-complexity medical decision-making or spends 20–29 minutes with the patient on the date of service.

To bill this code, the patient must have been seen by the same provider—or another clinician in the same specialty group—within the past three years. These visits typically cover follow-up care, management of minor acute problems, prescription adjustments, or ongoing monitoring of stable chronic conditions.

Documentation Requirements

Accurate documentation is essential for billing CPT 99213 correctly. Providers can support this code using either medical decision making (MDM) or time-based reporting, each with its own specific standards:

Medical Decision Making (MDM) Criteria

For CPT 99213, the required level is low-complexity MDM. Documentation must address three main elements:

Problems Addressed

The record should identify the conditions managed during the visit. Examples include:

One or more stable chronic illnesses (e.g., controlled hypertension or diabetes).

An uncomplicated acute condition (e.g., mild asthma episode, UTI, or simple rash).

Data Reviewed

The note should show review of limited clinical information, such as basic lab results, diagnostic tests, or external provider notes.

Risk Level

Documentation must confirm a low risk of complications, morbidity, or mortality. This may involve routine medication refills or straightforward care adjustments.

Time-Based Documentation

If using time instead of MDM, CPT 99213 applies when 20–29 minutes are spent on the date of service. The record should specify tasks performed, which may include:

Reviewing prior records and test results.

Conducting a medically necessary exam.

Documenting findings in the electronic health record (EHR).

Counseling or educating the patient/caregiver.

Ordering tests, prescriptions, or procedures.

Coordinating care with other healthcare providers.

Other Key Documentation Elements

To fully support billing, every note should also include:

Chief Complaint & History – Reason for the visit and brief history of present illness.

Exam Findings – While not always required, including a focused exam strengthens the record.

Assessment & Plan – Summary of diagnosis, treatment strategy, and follow-up instructions.

Encounter Details – Date of service and, if applicable, exact time spent.

Medical Necessity – A clear explanation of why the visit was needed and why CPT 99213 was the correct service level.

Billing Guidelines

Correct billing for CPT 99213 is critical to prevent denials and maintain compliance with payer regulations. Providers can achieve accuracy by following these key guidelines:

Patient Status and Setting

CPT 99213 applies only to established patients—those who have been seen by the same provider or another provider of the same specialty in the same group within the past three years. The service must occur in an office or outpatient setting. Encounters in the ER or inpatient facilities require different E/M codes.

Code Selection Criteria

This code may be chosen based on low-complexity medical decision making (MDM) or time spent.

MDM: Appropriate for stable chronic conditions, minor acute problems, or low-risk treatment decisions.

Time-Based: Billable if the provider spends 20–29 minutes on the date of service. If the visit involves more complexity or exceeds this time, a higher-level code such as 99214 should be used.

Modifiers and Payer Rules

Modifiers may be necessary for accurate billing. For example, modifier 25 should be added when a significant, separately identifiable procedure is performed at the same visit. Telehealth encounters may also qualify, but requirements vary by payer. Always review the latest Medicare, Medicaid, and commercial insurance guidelines before submission.

Claim Submission Essentials

Claims must be complete and properly linked to ICD-10 codes that support medical necessity. Submissions should also include the provider’s credentials, specialty, and verification of the patient’s insurance coverage. In some cases, prior authorization may be needed, so confirming this in advance helps prevent payment delays.

Reimbursement Tips

Medicare typically reimburses CPT 99213 at around $90–$95, while commercial insurance payments vary based on provider contracts. Reimbursement amounts can be improved by focusing on the following strategies:

Leverage Tools for Accuracy

Using EHR templates and checklists helps providers capture all required documentation elements. Templates guide clinical notes, while checklists ensure that decision-making and reviewed data are recorded. These tools promote standardized documentation and correct coding, which ultimately improves reimbursement outcomes.

Implement Ongoing Monitoring and Audits

Regularly reviewing 99213 encounters allows practices to catch errors early and stay compliant. Internal audits can uncover gaps in documentation or coding that may lead to denials. In addition, ongoing training for providers and coders on the latest E/M rules ensures adherence to current standards.

Prevent Coding Errors

Accurate coding is essential—undercoding results in lost revenue, while overcoding increases the risk of audits and penalties. The best practice is to code precisely and ensure documentation fully supports the billed service level.
