CPT® Code 99214

Quick Reference

• Code definition: 99214 covers an established patient office or outpatient E/M visit requiring a medically appropriate history and/or examination with moderate Medical Decision Making (MDM), or total provider time of 30 minutes or more on the date of the encounter.
• Key billing rule: Code level is determined by either moderate MDM (2 of 3 MDM elements at moderate) OR total physician/QHP time of 30 to 39 minutes on the date of service; the provider chooses which method to apply, and the choice must be documented.
• Modifier essentials: Modifier 25 is required when 99214 is billed on the same date as a procedure (present on approximately 72.85% of 99214 claims). Modifier 95 or GT applies for synchronous audio/video telehealth. Modifier 57 applies when the visit results in a decision for major surgery.
• Documentation must-have: For MDM-based selection, the record must document the specific problems addressed, data reviewed/ordered/discussed, and the management decision — especially any prescription drug change — not merely a medication list.
• Top confusion point: Prescription drug management (initiating, modifying, or discontinuing a prescription) satisfies the Moderate Risk element by itself. Documenting a refill without an explicit management decision does not meet this threshold and will not survive audit.
• Payer alert: Medicare allows add-on G2211 for longitudinal care complexity; this is Medicare-only and not reportable with commercial payers. Split/shared visit substantive portion rules apply in facility settings effective January 1, 2023.
• MUE: 2 units per date of service per provider; in practice, 1 unit per encounter per provider is expected.

When to Use This Code

Clinical Indications

99214 applies to established patient encounters where clinical complexity reaches the moderate MDM threshold or where total physician/QHP time reaches 30 minutes. Specific scenarios that support this code:

• Two or more stable chronic illnesses managed at a single visit (e.g., hypertension, hyperlipidemia, and type 2 diabetes addressed together)
• One chronic illness with exacerbation, progression, or adverse treatment effects (e.g., COPD with worsening dyspnea, poorly controlled diabetes with rising A1c, medication side effect requiring a regimen change)
• One undiagnosed new problem with uncertain prognosis (e.g., new onset chest pain requiring workup)
• One acute illness with systemic symptoms, such as fever, vomiting, or dehydration (e.g., pyelonephritis, community-acquired pneumonia)
• One acute, complicated injury requiring management beyond minor wound care

Scope Boundaries

99214 is for established patients only: a patient who has received professional services from the same physician, QHP, or another physician/QHP of the same specialty in the same group within the past three years. New patients at equivalent complexity use 99204.

The 2021 AMA E/M guideline overhaul eliminated history and physical exam level scoring. A medically appropriate history and/or examination must still be documented, but its extent is determined by clinical need rather than a scoring formula.

What falls outside this code:

• Encounters with straightforward or low-complexity MDM use 99213 or 99212
• Encounters with high-complexity MDM or total time of 40 minutes or more use 99215
• New patient encounters at moderate complexity use 99204
• Facility-based encounters (hospital, observation, SNF) fall under separate E/M code ranges

Time-Based Coding

When using total time as the basis for code selection, all time the physician or QHP spends on the date of the encounter counts: preparing to see the patient, taking history, performing exam, reviewing and ordering tests, counseling, documenting, and care coordination. Clinical staff time does not count toward the physician's or QHP's total for level selection purposes.

Time thresholds for established patient office E/M:

Worked example: A provider spends 12 minutes reviewing prior records before the visit, 15 minutes face-to-face with the patient, and 6 minutes documenting afterward. Total = 33 minutes, which supports 99214. The record must state the total time (e.g., "Total time today: 33 minutes").

99417 adds onto 99215 only, beginning at 55 minutes total. It does not extend 99214: once total time reaches 40 minutes, the service codes as 99215.

Code Differentiation Table

The most critical differentiator between 99213 and 99214 is Moderate Risk. When a provider initiates, modifies, or discontinues a prescription medication, that single decision elevates Risk to Moderate. If at least one other element (Problems or Data) also reaches Moderate, the encounter supports 99214. Encounters where the only management is observation, return precautions, or OTC recommendations stay at Low Risk and typically support 99213 or lower.

Billing & Modifier Rules

Modifier 25

Modifier 25 is the most frequently used modifier with 99214 (present on approximately 72.85% of claims). Apply it when a procedure is performed on the same date and the E/M represents a significant, separately identifiable service above and beyond the pre/post-service work bundled into the procedure. Both services must be independently documented. Different diagnoses are not required, but documentation must demonstrate the E/M involved work distinct from the procedure.

Modifier 57

Use modifier 57 when the 99214 encounter results in the initial decision to perform major surgery (90-day global period). This applies when the visit occurs on the day before or the day of surgery. For procedures with 0-day or 10-day global periods on the same date, modifier 25 applies instead.

Telehealth Modifiers

• Modifier 95: Synchronous audio/video telemedicine (AMA); appended when 99214 is delivered via real-time interactive audio/video
• Modifier GT: Medicare-specific synchronous audio/video telehealth equivalent
• Modifier GQ: Medicare: asynchronous (store-and-forward) telemedicine
• Modifier FQ: Medicare: audio-only telehealth when the patient lacks video capability

Congress extended Medicare telehealth flexibilities through 2025, permitting 99214 delivery from the patient's home without originating site restrictions.

Add-On Codes

Bundling Alerts

• MUE = 2: A maximum of 2 units per date of service per provider is considered medically unlikely; in practice, 1 unit per encounter is expected. A second unit requires split/shared documentation or similarly rare justification.
• 99417 does not add on to 99214: Once time-based selection reaches 40 minutes, the service codes as 99215. Then 99417 applies for each additional 15 minutes at 55 minutes or more.
• Same-day preventive visit: 99214-25 may be billed alongside preventive medicine codes (99381-99397) when a separately identifiable problem-oriented E/M is performed and documented.
• Prolonged non-face-to-face (99358-99359): Cannot be billed on the same date as 99214.
• Online/telephone services (99421-99423, 98016): Cannot bill these communication codes on the same day as 99214.

Documentation Essentials

MDM-Based Documentation

All three MDM elements must be addressed in the record. To support 99214, at least two must reach Moderate:

1. Problems Addressed Document each condition addressed with enough specificity to identify complexity level. "Hypertension, stable" and "type 2 diabetes, stable" each count as one stable chronic condition; two together satisfy Moderate Problems. "Type 2 diabetes with A1c rising from 7.2 to 8.5" documents progression and alone satisfies Moderate Problems. Simply listing diagnoses without addressing them at the visit does not count.

2. Amount and Complexity of Data For Category 1 (need three items from any combination):

• "Reviewed today's CMP results: potassium 3.8, creatinine 1.0..."
• "Reviewed cardiology note from [date]: per Dr. Smith, no change in valve status"
• "Ordered HbA1c and fasting lipid panel"

Each unique external source and each unique test counts separately. For Category 2 (independent interpretation), the provider must record their own interpretation, not just "reviewed X-ray report." For Category 3 (external discussion), the provider must document an actual discussion with an external physician, specialist, or pharmacist, including with whom and the substance of the discussion.

3. Risk of Complications For prescription drug management, document the active decision explicitly: "Started metformin 500 mg daily for T2DM," "Increased lisinopril from 10 to 20 mg due to persistent hypertension," or "Discontinued metformin due to declining GFR." A printed or copied medication list without a documented decision does not satisfy this element.

Time-Based Documentation

Record total time in minutes and identify that total time was used for code level selection. Including the activities performed on the date of service (chart review, examination, documentation, care coordination) provides additional support.

Audit Red Flags

• Cloned or copy-pasted notes: Identical or near-identical documentation across multiple visits is a top RAC and TPE audit trigger. Each encounter must reflect the work actually performed that day, individualized to the patient's current status.
• Medication list substituting for MDM Risk documentation: Listing current medications without an explicit management decision does not satisfy Moderate Risk.
• Total time absent when time-based coding used: Without documented time, the claim reverts to MDM as the only available basis, which may support a lower level.
• Inflated data counts: Counting the same item in multiple data categories, or counting reviewing a result and ordering that same result in the same encounter as two items (which is correct) versus counting one item twice (which is not).
• No history or exam documentation: While history and exam are not scored, a completely absent clinical assessment draws medical necessity scrutiny and audit attention.

Medicare, Commercial & Medicaid Payer Rules

Medicare

Split/Shared Visits (Facility Setting): When a physician and an NPP of the same group each contribute to a visit, the provider who performs the substantive portion bills the service. Substantive portion means more than half of total time, or the history, exam, or MDM performed by the billing provider. Each provider's role and time contribution must be documented. This rule applies in facility settings; incident-to rules govern non-facility (office) settings instead.

Incident-to (Non-Facility): An NPP's service may be billed under the supervising physician's NPI at 100% of the Medicare fee schedule when: the patient is established, the supervising physician has personally treated the patient for the same condition and established the plan of care, and the supervising physician is directly supervising (physically present in the office suite and immediately available). Incident-to is unavailable for new problems the supervising physician has not previously managed.

G2211 (Add-on, Medicare Only): For physicians or QHPs providing longitudinal primary or specialty care where the visit represents a continuing focal point for all needed health care, or ongoing management of a single serious or complex condition, Medicare permits add-on G2211 to capture the inherent complexity of that care relationship. G2211 is reportable with 99214 or 99215 and is not billable by commercial payers.

PEPPER Benchmarking: CMS distributes PEPPER reports comparing a practice's E/M level distribution against peers. Practices billing 99214 or 99215 for a substantially higher percentage of encounters than comparators may receive Targeted Probe and Educate (TPE) requests. Systematic upcoding across nearly all established patient visits is among the most common patterns identified by Recovery Audit Contractors.

Telehealth (Through 2025): Medicare waives the originating site requirement through 2025, permitting 99214 delivery from the patient's home. Use modifier 95 or GT for synchronous audio/video; modifier FQ for audio-only when the patient lacks video capability.

Commercial Payers

Most commercial payers have adopted the 2021 MDM framework and accept total time for code selection. Notable variations:

• Automated claims editing systems may downcode 99214 to 99213 when the diagnosis submitted does not algorithmically match expected complexity, even when documentation supports the billed level; appeals with medical record excerpts are often successful
• Some payers apply frequency edits for practices with atypical E/M level distributions relative to specialty peers
• Telehealth coverage for synchronous audio/video (modifier 95) is broadly covered; audio-only reimbursement varies by plan and state

Medicaid

Medicaid managed care plan rules vary by state. Common variations include per-beneficiary frequency limitations not present in Medicare, prior authorization requirements for specialist E/M visits above a certain level, and state-specific modifier or code substitution requirements for telehealth. Verify with each state Medicaid agency or managed care organization.

Common Denials & Prevention

Denial: Documentation Does Not Support Level of Service Root cause: The medical record supports only one MDM element at Moderate (or none), yet 99214 was billed. For example: one stable chronic condition (Low Problems), two data items (Low Data), and only a dietary counseling recommendation (Low Risk). Prevention: Confirm 2 of 3 MDM elements reach Moderate before submitting. An MDM worksheet embedded in the note template reduces this error at the point of documentation.

Denial: Modifier 25 Missing; E/M Bundled into Procedure Root cause: 99214 was submitted without modifier 25 on the same date as a procedure that carries a global period, including 0-day globals. The payer automatically bundles the E/M into the procedure payment. Prevention: Implement charge capture rules that prompt for modifier 25 review whenever any procedure code appears alongside a 99214 on the same claim. Verify the E/M is independently documented before appending the modifier.

Denial: Duplicate Billing Root cause: A second 99214 was submitted for the same patient, same provider, same date without appropriate split/shared documentation. The MUE of 2 provides a technical cap, but most payers deny duplicate E/M units without supporting documentation. Prevention: Bill one E/M per provider per date. In facility split/shared encounters, ensure documentation identifies the substantive portion and the billing provider before submitting.

Denial: Incident-to Requirements Not Met Root cause: An NPP billed 99214 incident-to for a new problem the supervising physician had not previously treated, or the supervising physician was not present in the office suite during the encounter. Prevention: Audit incident-to claims quarterly. New conditions must be billed under the NPP's own NPI at 85% of the fee schedule until the supervising physician personally evaluates the patient and documents an updated plan of care.

Denial: Total Time Not Documented (Time-Based Selection) Root cause: The provider selected 99214 based on time but did not document total time, leaving MDM as the only available basis. If MDM elements support only Low or Straightforward complexity, the claim will be downcoded. Prevention: Standardize note templates to include a required total time field. If using MDM as the basis, document MDM elements explicitly and omit time documentation to avoid conflicting signals.

Coding Scenarios

Scenario: An established patient with hypertension and type 2 diabetes (both stable) presents for a routine 3-month follow-up. The provider reviews the HbA1c result ordered at the last visit and today's in-office blood pressure reading. Both medications (lisinopril and metformin) are continued and refilled.

Correct coding: 99214

Why: Problems: 2 stable chronic illnesses = Moderate. Risk: prescription drug management (continuing 2 prescriptions with an active continuation decision) = Moderate. Two of 3 elements at Moderate supports 99214, even with Data at Low (only 2 Category 1 items reviewed). If total time was also 30 minutes or more, the time basis independently supports the same level.

Scenario: An established patient presents with 2 days of dysuria, frequency, and fever of 38.8°C. The provider takes a history, performs an abdominal exam, reviews the in-office urinalysis result, reviews a prior urine culture from an outside lab, orders a new urine culture, and prescribes trimethoprim/sulfamethoxazole.

Correct coding: 99214 with an appropriate UTI or pyelonephritis diagnosis

Why: Problems: acute illness with systemic symptoms (fever) = Moderate. Data: in-office UA result (1) + outside urine culture (2) + new urine culture ordered (3) = 3 Category 1 items = Moderate. Risk: prescription antibiotic = Moderate. All 3 elements at Moderate; 99214 is clearly supported and 99215 would require High on 2 of 3 elements.

Scenario: The same established patient is also seen for uncontrolled hypertension at the same visit; the provider adjusts the antihypertensive and also removes a sebaceous cyst (CPT 10040) during the encounter.

Correct coding: 99214-25 and 10040

Why: Modifier 25 is required on 99214 because a procedure with a global period is billed on the same date. The E/M (medication adjustment, lab review, blood pressure management) is a significant, separately identifiable service above and beyond the pre/post-service work of the cyst removal. Both must be documented independently.

Scenario: An NPP sees an established patient for a worsening asthma exacerbation. The supervising physician previously treated this patient for asthma and established the care plan. The NPP adjusts the inhaler regimen and orders pulmonary function testing. The supervising physician is physically present in the office suite but did not participate in this visit.

Correct coding: 99214 billed under the supervising physician's NPI (incident-to), or 99214 billed under the NPP's NPI at 85% of fee schedule if incident-to requirements are not confirmed

Why: Incident-to applies when the supervising physician previously managed the same condition and is directly supervising. If the supervising physician was not in the building, or if asthma was a new problem not previously treated by that physician, incident-to fails and the NPP must bill under their own NPI.
