Quick Answer: What Is 99203 cpt code?
99203 cpt code is used for a new patient office or other outpatient E/M service. When MDM is used for code selection, the service is low level (when using MDM at the highest level, the service would be low level). For total time, the service needs to be performed by the service provider as an allotted 30-44 minutes of qualifying total practitioner time on the date of the service.
| Field | CPT 99203 Information |
|---|---|
| CPT code | 99203 |
| Code family | Office or other outpatient E/M |
| Patient type | New patient |
| MDM level | Low |
| Time when time is used | 30–44 minutes |
| 2026 work RVU | 1.60 |
| 2026 non-facility total RVU | 3.52 |
| 2026 facility total RVU | 2.14 |
| 2026 non-QP conversion factor | Approximately $33.40 |
| 2026 QP conversion factor | Approximately $33.57 |
CMS has different conversion factors for clinicians who are not QPs and clinicians who are QPs in 2026. Thus, there is no single conversion factor to be used as the universal 2026 Medicare conversion factor.
What Is the 99203 CPT Code Description?
The description of the 99203 CPT code is a new patient office or other outpatient E/M service. Medically appropriate history and examination is required when clinically indicated. Low-level medical decision making is also part of the code if MDM determines the level of the services.
With time as the determinant of the code, the practitioner should be in service for 30-44 minutes on the date of service. The time includes qualifying physician or qualified healthcare professional work connected with the encounter. The code does not require a particular diagnosis. Rather, the meeting has to be clinically required and documented. The documentation should back the service given.
Who Qualifies as a New Patient?
A new patient usually is an individual for whom the same physician or another physician of the same specialty has not provided professional services in the same group within the last 3 years. Student status is important because it is a new patient office E/M code. A code family usually needs to be different for an established patient.
When patient status is not explicitly clear, coders need to validate with the appropriate definition and payer rules. Group practice and specialty relationships may impact determination.
When Should 99203 cpt code Be Used?
If the E/M service is provided to a new patient in his or her office or outpatient setting, then 99203 cpt code should be used. The encounter shall support the low level MDM or the time requirement for the encounter.
The AMA offers an example of a new patient who has a chronic condition that is stable or has an acute uncomplicated injury. This is just an example of the level of service, and does not limit the code to these diagnoses. The final code should be the actual encounter! Never base the E/M level based on diagnosis.
What Are the MDM Requirements for 99203 cpt code?
When medical decision making (MDM) is used to determine the E/M level, the code 99203 cpt code is used for low-level medical decision making.
The MDM framework evaluates three elements:
- Problems addressed
- Data reviewed and analyzed
- Risk of patient management
At least two of these three elements must meet or exceed the required low-level threshold for low MDM.
The level of the E/M service is not based on the diagnosis. Documentation should demonstrate that the problems were addressed and that the appropriate data review, analysis, and management decisions have been made to justify the reported level.
Problems Addressed
The problems element takes into account the number and complexity of the problems solved in the encounter. Any condition mentioned in the medical history is not automatically counted. Clinicians must actually discuss the problem in evaluation, assessment or management.
Data Reviewed and Analyzed
The data element is derived from the categories of data that have been reviewed and/or analyzed within the CPT MDM framework and meet the criteria for inclusion. This can be any combination of tests, documents, external notes, test results, or information from an independent historian, depending upon the type of encounter. Not all content in a patient’s chart is considered the data element.
Risk of Patient Management
The risk factor takes into account the risk involved in the decisions made on patient management during the encounter. The level of risk that is applicable must be supported by the specific management decision and circumstances of the patient. The MDM level does not automatically follow a medication related decision. The Coding Principles for the Management Decision (CPT MDM) approach should be used by the coder on the actual management decision in the record.
99203 cpt code Time Requirement
If total time is specified as the selection, the physician or other qualified health care professional must spend 30-44 minutes on the date of the encounter performing qualifying total time. If MDM is selected and it is documented to support the required level of MDM of 99203, then 30 minutes is not required.
If time is reported, the total should be the amount of qualifying time the physician or QHP spent on the date of the service providing the care. The time spent by Clinical Staff is not just another increment to the practitioner’s time.
Examples of qualifying work may include preparation for the encounter, evaluation and management of the patient, counseling and education, ordering medications or tests, documenting clinical information, interpreting results independently when applicable, and communicating with other professionals when applicable and meets the applicable E/M time requirements.
99203 Time vs MDM: Which Method Should Be Used?
The selection of 99203 cpt code, with either MDM or total time can be used. Physicians and QHPs can select the method that best fits the encounter in the CPT E/M framework.
| Selection Method | CPT 99203 Requirement |
|---|---|
| MDM | Low-level medical decision making |
| Time | 30 to 44 minutes |
| History | Medically appropriate |
| Examination | Medically appropriate |
If the provider provides low MDM, he or she does not have to spend 30 minutes. However, 30 minutes is not enough to document 99203 without proper documentation.
What Documentation Supports 99203 cpt code?
Documentation should indicate medical necessity and support the chosen E/M level. The record should show the problems tackled and clinical decisions made. For MDM-based selection, documentation should support the relevant MDM elements. At least two elements must meet the low-level threshold.
For time-based selection, the record should support qualifying total practitioner time. The documented time should correspond with work performed on the encounter date.
Useful documentation can include:
- Problems addressed during the visit
- Clinical assessment and management decisions
- Relevant data reviewed
- Tests ordered or evaluated
- Treatment recommendations
- Medication decisions when applicable
- Risk considerations
- Medical necessity
- Total time when used for code selection
- Follow-up planning
A longer note does not equal more E/M level. Documentation should provide a description of the actual work completed.
99203 cpt code RVU for 2026
For 2026, CPT 99203 has a work RVU of 1.60. The practice expense RVU is 1.76 (non-facility setting) and 0.38 (facility setting) while the malpractice RVU is 0.16.
| 2026 RVU Component | Non-Facility | Facility |
|---|---|---|
| Work RVU | 1.60 | 1.60 |
| Practice Expense RVU | 1.76 | 0.38 |
| Malpractice RVU | 0.16 | 0.16 |
| Total RVUs | 3.52 | 2.14 |
Facility and non-facility differences in total RVUs are largely driven by the practice expense component. Medicare RVUs are relative resource values that are part of the Medicare Physician Fee Schedule methodology, not a provider’s reimbursement or a patient’s out-of-pocket cost.
99203 cpt code Reimbursement for 2026
Using the 2026 Medicare conversion factor of $33.4009, the illustrative national payment amounts are:
- Non-facility: 3.52 × $33.4009 = approximately $117.57
- Facility: 2.14 × $33.4009 = approximately $71.48
These are illustrative national payment amounts, not guaranteed Medicare reimbursement rates.
Actual Medicare payment can differ because geographic adjustments are applied to the work, practice expense, and malpractice components. In addition, 2026 uses a separate conversion factor for qualifying APM participants (QPs), so the applicable payment can differ based on clinician status.
| Setting | Total RVU | Illustrative Amount Using 2026 Non-QP CF* |
|---|---|---|
| Non-facility | 3.52 | $117.57 |
| Facility | 2.14 | $71.48 |
How Is Medicare Payment for 99203 cpt code Calculated?
Medicare payment generally combines the relevant RVU components with geographic adjustments. The adjusted value is then multiplied by the applicable conversion factor.
The general calculation is:
Payment = [(Work RVU × Work GPCI) + (PE RVU × PE GPCI) + (MP RVU × MP GPCI)] × Conversion Factor
The actual Medicare amount can therefore differ from the national figure. Local GPCI values affect the final payment.
What Is the Cost of 99203 cpt code?
There is no fixed national 99203 CPT code cost for each and every patient. Patient responsibility will be determined by the insurance coverage, deductibles, coinsurance, copayments and the provider’s applicable contract.
The Medicare allowed amount is not necessarily the patient’s responsibility. Under these “rules,” Medicare beneficiaries may be responsible for cost-sharing. Commercial insurance policies can yield various payouts. There are also providers and locations that could charge different prices for self-pay. Thus, the CPT code is not the only factor that will work out what a patient pays.
99203 vs 99202: Key Differences
The two codes, CPT 99202 and 99203, refer to new patient offices or new outpatient E/M services. The main difference is the amount of MDM or qualifying total time.
| Feature | CPT 99202 | CPT 99203 |
|---|---|---|
| Patient type | New | New |
| MDM | Straightforward | Low |
| Time | 15 to 29 minutes | 30 to 44 minutes |
| Service level | Level 2 | Level 3 |
A longer visit does not automatically require 99203 cpt code. The provider can select the code using MDM when that method supports the service. Likewise, a complicated diagnosis does not automatically establish a higher level. The documented work must support the selected E/M service.
99203 vs 99204: Key Coding Differences
99203 is different from 99204 because of the level of MDM or total time. These codes are for new patient offices or new patient E/M services.
| Feature | CPT 99203 | CPT 99204 |
|---|---|---|
| Patient type | New | New |
| MDM | Low | Moderate |
| Time | 30 to 44 minutes | 45 to 59 minutes |
| Service level | Level 3 | Level 4 |
| 2026 work RVU | 1.60 | 2.60 |
The provider should only use 99204 for moderate MDM or the applicable time period as indicated in the documentation. The code should not be based solely on the diagnosis.
What Modifiers Apply to 99203 cpt code?
Modifier is not required on each claim for CPT 99203. The selection of modifiers will be based on the specific situation of the encounter.
Modifier 25: Separately Identifiable E/M Service
If the significant, separately identifiable E/M service is rendered on the same date as a procedure or service, then modifier 25 may apply. The documentation should support the distinct E/M work. The modifier should not be added merely to bypass an NCCI or payer edit.
Telehealth Modifiers: Payer-Specific Requirements
Telehealth claims can involve specific modifier and place-of-service requirements. Medicare and commercial payers may apply different policies. The correct reporting approach should be verified against the current payer guidance. Coders should avoid assuming that one telehealth rule applies to every payer.
Modifier Selection: Match the Actual Encounter
Modifiers should describe the actual circumstances of the service. Unsupported modifiers can create claim problems and audit concerns. Medical records should contain adequate detail to support any modifier which is reported with 99203.
Common 99203 cpt code Billing Mistakes
Mistake 1: Treating Every New Patient as 99203
New patients are not automatically assigned to 99203. The encounter must be performed to meet the required MDM and/or time requirements.
Mistake 2: Counting Diagnoses Instead of Problems Addressed
A long diagnosis list does not automatically establish low MDM. The provider must address the relevant problems during the encounter.
Mistake 3: Assuming Thirty Minutes Is Always Required
Thirty minutes applies when time determines the code. It is not required when MDM independently supports 99203.
Mistake 4: Counting Staff Time as Practitioner Time
Staff time should not simply be added to physician or QHP time. The reported total must represent qualifying practitioner work.
Mistake 5: Automatically Adding Modifier 25
Modifier 25 requires a significant and separately identifiable E/M service. Documentation must support the distinct work performed.
Mistake 6: Using One Reimbursement Amount Everywhere
Medicare payment varies by locality and setting. Commercial reimbursement depends on payer contracts and applicable billing policies.
Mistake 7: Confusing New and Established Patients
Patient status directly affects code family selection. Coders should verify the patient’s relationship with the physician or group.
99203 cpt code Coding Examples
Example 1: Low MDM Supports 99203 cpt code
A new patient presents with an acute uncomplicated illness. The clinician evaluates the condition and establishes an appropriate management plan. The documentation supports the low MDM threshold based on at least two of the three MDM elements.
CPT 99203 may be appropriate, assuming medical necessity and all other applicable requirements are satisfied. The diagnosis itself does not automatically determine the E/M level.
Example 2: Time Supports 99203 cpt code
A new patient receives an office E/M service requiring 36 minutes of qualifying physician or QHP total time on the date of service. The documentation supports the reported total time, and time is used as the method for selecting the E/M level. Because 36 minutes falls within the 30–44 minute range, CPT 99203 may be reported when all other applicable requirements are satisfied.
Example 3: 46 Minutes May Support 99203 cpt code
A new patient encounter requires 46 minutes of qualifying total physician or QHP time on the date of service. If time is used for code selection, 46 minutes falls within the 45–59 minute range for CPT 99204. The code should not be selected based on the length of the clinical note. The documented time must represent qualifying practitioner work performed on the date of service.
CPT 99203 and Medical Necessity
Medical necessity is an important consideration when reporting CPT 99203. The documentation should explain why the patient required the evaluation and management service.
A lengthy note does not automatically establish medical necessity. Multiple diagnoses also do not automatically justify a higher E/M level.
The clinical record should connect the problems addressed with the provider’s assessment and management decisions. This connection helps support accurate coding and audit review.
99203 cpt code Audit Considerations
Auditors may evaluate whether the documentation supports the reported E/M level. They can review patient status, MDM, time, medical necessity, and modifier use. For MDM-based coding, the record should support the applicable MDM elements. For time-based coding, the documentation should support qualifying total practitioner time.
Modifier claims can receive additional review. The record should demonstrate that any reported modifier accurately represents the service circumstances. Consistent documentation helps reduce coding disputes. It also makes internal and external audits easier to support.
How Should Coders Review CPT 99203?
Start by confirming that the patient qualifies as new. Then determine whether MDM or total time supports the reported service. If MDM determines the level, review problems, data, and risk. At least two elements must meet the low-level requirements.
If time determines the level, verify qualifying total practitioner time. Then review medical necessity, documentation, modifiers, place of service, and payer requirements. This process keeps code selection separate from reimbursement expectations. It also helps reduce unsupported level selection.
Key Takeaways About 99203 cpt code
CPT 99203 is the code for new patient office visits and outpatient E/M services. Comparable selection requires medical need and documented complexity of service. If applicable, low MDM can assist in supporting the code. In addition, 30 to 44 minutes can be used as a support for time-based selection. The 2026 work RVU for 99203 is 1.60.
There are different Medicare reimbursements based on location and facility. Modifiers also apply to the specifics of the services provided. Documenting with care will aid accurate coding and minimize claim problems. Before submitting claims, always double-check with Medicare and payers what they are looking for currently.
