How do 99213, 99214 compare side by side?
The table below compares 99213, 99214 across 16 procurement-relevant dimensions, from service through prolonged services.
Side-by-side comparison
| Dimension | 99213 | 99214 |

| Element 3 — risk | <strong>Low risk</strong> of morbidity from additional diagnostic testing or treatment. CPT gives no example list at this level. | <strong>Moderate risk</strong> of morbidity from additional diagnostic testing or treatment. CPT's <em>examples only</em>: prescription drug management; decision regarding minor surgery with identified patient or procedure risk factors; decision regarding elective major surgery without identified patient or procedure risk factors; diagnosis or treatment significantly limited by social determinants of health. |
| How many elements you need | MDM has three elements — problems addressed, data reviewed and analyzed, and risk. Per CPT, "to qualify for a particular level of MDM, two of the three elements for that level of MDM must be met or exceeded." You never need all three. | MDM has three elements — problems addressed, data reviewed and analyzed, and risk. Per CPT, "to qualify for a particular level of MDM, two of the three elements for that level of MDM must be met or exceeded." You never need all three. |
| The usual tipping point | One stable chronic illness, or one acute uncomplicated problem, with no medication decision and little or no outside data. | A second stable chronic illness, <em>or</em> a prescription drug decision, <em>or</em> an exacerbation of one chronic illness. Any two moderate elements carry the visit. |
| Typical presenting problem | Controlled hypothyroidism on a stable dose; uncomplicated cystitis; a resolving viral URI. | Type 2 diabetes plus hypertension, both stable, medications reviewed and adjusted; asthma with an exacerbation; a new undiagnosed problem with uncertain prognosis. |
| History and examination | Not a factor. Since 1 January 2021 CPT states that "the extent of history and physical examination is not an element in selection of the level of these E/M service codes." A comprehensive ROS cannot raise the level, and a brief note cannot lower it. | Not a factor.

A comprehensive ROS cannot raise the level, and a brief note cannot lower it. |
| What the note must actually show | That the problem was <em>addressed</em> — evaluated or treated, not merely listed. CPT: noting that another professional is managing a problem, without documented additional assessment or care coordination, does not qualify. | The same, plus enough to evidence the second moderate element: the specific drug decision (start, stop, change, or a documented decision to continue), or the named data sources, or the exacerbation. |
| Why it gets downcoded | Rarely challenged — 99213 is the level auditors downcode <em>to</em>. | A problem list pasted forward with no evidence anything was evaluated; "continue meds" with no decision documented; counting an ordered test and its later result as two separate data points. |
| Measured audit exposure (CERT) | Improper payment rate <strong>2.1%</strong> (95% CI 0.2-4.1%), $101m projected. But where 99213 <em>is</em> found improper, <strong>88.4%</strong> of it is incorrect coding — and the established-office category downcodes and upcodes both exist, so a 99213 that should have been a 99214 is also an error. | Improper payment rate <strong>5.0%</strong> (95% CI 3.3-6.6%), $460m projected — the largest dollar figure of any single E/M code after 99233. <strong>62.5%</strong> of that is incorrect coding rather than missing documentation. |
| Which direction the errors run | For office visits, established patients as a category: $854m improper, 5.3% rate. Upcoding accounts for 3.1% and downcoding 0.4% — roughly <strong>7.3:1</strong>. | CMS's ranked root causes for this category put "documentation supports lower level of E/M service than what was billed" first at 120 sampled claims, against just <strong>7</strong> for the reverse. The system is calibrated to find overstatement. |
| If you use time | Document the total time. Counts: preparing to see the patient; obtaining/reviewing separately obtained history; performing the exam/evaluation; counseling and educating patient/family/caregiver; ordering medications, tests, or procedures; referring and communicating with other health professionals (when not separately reported); documenting in the record; independently interpreting results (not separately reported) and communicating them; care coordination (not separately reported). Does <strong>not</strong> count: services reported separately, travel, and teaching that is general and not limited to the management of this specific patient. | Same rules. Only distinct time counts on a split or shared visit — if two people jointly meet with the patient, only one person's time is counted. |
| Prolonged services | Not applicable. | Not at this level. In the office family 99417 attaches only to 99215, from 55 minutes — and only where the primary service was selected on <strong>time alone</strong>. Under Medicare the equivalent is G2212, which starts later still (69 minutes with 99215). |
Common questions
Common questions about 99213 vs 99214
My patient has two stable chronic illnesses and I renewed their medications. Is that a 99213 or a 99214?
+
On those facts alone it is a 99214. "2 or more stable, chronic illnesses" is the moderate descriptor for problems addressed, and prescription drug management is a CPT-listed example of moderate risk. That is two of the three elements at moderate, and two of three is all CPT requires. You do not need the data element, and you do not need a complicated visit — the moderate bar is a description of the clinical work, not a reward for difficulty.
How many minutes is a 99214?
+
The CPT descriptor for 99214 reads "30-39 minutes of total time is spent on the date of the encounter." Thirty minutes is the floor to reach the level; at 40 minutes the visit is a 99215. But time is an alternative to MDM, not an additional requirement — if your MDM is moderate, a 12-minute visit is still a 99214, and you do not need to record the time at all. Only document total time if time is the basis you are using.
Does continuing an existing prescription count as prescription drug management?
+
Generally yes, provided a decision is documented — but be aware this is the most disputed square on the whole table, and your MAC's wording matters. CPT itself never defines "prescription drug management"; the phrase appears only as a moderate-risk example, so every working rule on it is contractor or specialty-society interpretation rather than CPT text. Noridian and Novitas both state that it "does not require a new drug, a new dosage, or a discontinuation of a current prescription," while adding that "an encounter documented as only a prescription refill without documentation of a problem addressed would not suffice." CGS is the most permissive: "A decision to maintain the current medication is sufficient. Credit is given as long as the documentation clearly indicates that decision-making took place in regard to the medication(s)." AAFP sets the highest bar, wanting the refill's purpose, any dosage adjustment, and a brief management statement linking the drug to the problem addressed. Document to the AAFP standard and you are safe everywhere; document to the CGS standard outside CGS's jurisdiction and you are exposed.
Does recommending an over-the-counter medication count?
+
No, not on its own. Noridian and Novitas use identical language: "An order for an over the counter (OTC) drug does not count as prescription drug management. However, managing the patient's prescription drugs in connection with adding an OTC or supplement would show prescription drug management." So telling a patient to start a proton pump inhibitor off the shelf is not the moderate-risk element; adjusting their prescribed regimen around that addition is. Note too that prescription drug management supports only the <em>risk</em> element — you still need a second element at moderate, from problems or data, to reach 99214.
If I order a test and then review the result, is that two data points?
+
No. CPT addresses this directly twice over: "Tests ordered are presumed to be analyzed when the results are reported. Therefore, when they are ordered during an encounter, they are counted in that encounter," and separately, "ordering a test is included in the category of test result(s) and the review of the test result is part of the encounter and not a subsequent encounter." One unique test ordered is one data element, and reviewing that same result later does not create a second. This is the classic double-dip and one of the easiest errors for an auditor to spot. Two related limits: a test whose professional component you report separately cannot be counted as a data element at all, and a clinical laboratory panel such as a basic metabolic panel is a single test, not one per analyte.
Is billing a lot of 99214s an audit red flag on its own?
+
No, and the national data makes that concrete. 99214 has been the most-billed established office visit for years, and its share has been rising: on CMS Medicare utilisation data, 99214 grew from 48.4% of established office visits in 2019 to 53.8% in 2024, while 99213 fell from 42.0% to 36.0%. The inflection is 2021 — the year the MDM and time rules took effect. A distribution weighted toward 99214 is now the norm rather than an outlier. What draws scrutiny is a distribution the panel cannot explain, combined with notes that look identical to one another. CMS's CERT programme puts 99214's improper payment rate at 5.0%, and 62.5% of those errors are incorrect coding rather than missing documentation — meaning the note existed and simply did not carry the level. The defence is never the percentage; it is that each individual note shows two moderate elements.
Is copying forward the last note a problem if the patient genuinely has not changed?
+
Yes, and MACs treat it as a medical necessity failure rather than a coding slip. Palmetto GBA's guidance is blunt: "Cloning occurs when medical documentation is the same from beneficiary to beneficiary. It would not be expected that every patient had the exact same problem, symptoms and required the exact same treatment. This cloned documentation does not meet medical necessity requirements for coverage of services rendered due to the lack of specific, individual information." It goes on to say identification of cloned documentation "will lead to denial of services for lack of medical necessity and recoupment of all overpayments made." CMS separately notes that HHS-OIG has identified record cloning and copy-and-paste among EHR features improperly used to facilitate fraud, waste and abuse. Carrying structure forward is fine; carrying the assessment forward unchanged is what fails.
Can I use MDM for one visit and time for the next?
+
Yes. CPT lets you select the level of each E/M service by either the level of MDM or the total time for that encounter, and the choice is made per encounter. Most clinicians code by MDM by default and fall back to time on the occasional visit where the counselling and coordination were long but the decision making was not complex. The only place it is not a free choice is prolonged services: 99417 may be reported only when the primary service was selected using time alone.
Do I still need a review of systems and a full exam to bill a 99214?
+
No. Since 1 January 2021 the codes require only "a medically appropriate history and/or examination," and CPT states plainly that the extent of history and physical examination is not an element in selecting the level. The treating clinician decides what is medically appropriate. Padding a note with a ten-system ROS adds no support to a 99214 and, when it is obviously templated, actively undermines the note's credibility.
