1. Which CPT® code is reported for this established patient visit based on 35 minutes of total time?
   Answer: 99214 CPT® 99214 describes an established patient office visit with moderate MDM or 30 to 39 minutes of total time — the correct code when the documented total time falls within the 30-39 minute range. The physician documents 35 minutes, which places the encounter in the 99214 time range. The encounter would also support moderate MDM independently: two stable chronic illnesses plus a new acute complaint (three problems, with COPD adjustment via prescription change constituting moderate risk), consistent with 99214 via the MDM pathway as well. Code 99213 applies to 20-29 minutes; 35 minutes exceeds this range. Code 99215 requires 40-54 minutes or high MDM. Code 99212 requires 10-19 minutes. Either MDM or total time may be used to select the E/M level; when both pathways lead to the same code, the documentation is internally consistent and well-supported.
2. Which CPT® code is reported for this new patient office visit based on 50 minutes of total time?
   Answer: 99204 CPT® 99204 describes a new patient office visit with moderate MDM or 45 to 59 minutes of total time — the correct code for a new patient encounter where the physician documents 50 minutes of total time on the date of service. The 2021 E/M guidelines define total time for office-based visits as all time spent on the day of the encounter related to the visit, including pre-service review of records, the face-to-face encounter, and post-service documentation and care coordination. Code 99205 applies to 60-74 minutes for a new patient; 50 minutes does not reach this threshold. Code 99203 applies to 30-44 minutes; 50 minutes exceeds this range. Code 99202 applies to 15-29 minutes. For new patients: 15-29 min = 99202; 30-44 min = 99203; 45-59 min = 99204; 60-74 min = 99205; 75-89 min = 99205 with prolonged service add-on.
3. An established patient reports a breast mass she noticed during self-exam one week ago. The physician examines the mass, orders a bilateral diagnostic mammogram for evaluation within the week, and advises the patient to return for results. No prescription is written and no formal specialist referral is placed at this encounter. Which CPT® code is reported?
   Answer: 99213 CPT® 99213 describes an established patient office visit with low medical decision making (or 20-29 minutes of total time) — the correct code here because only one of three MDM elements reaches the moderate level. The breast mass is a new problem with uncertain prognosis (possible malignancy cannot yet be excluded), which classifies it as a moderate-level problem. However, moderate MDM requires at least two of three elements to meet the moderate threshold. Ordering one diagnostic test (mammogram) represents one Category 1 data element — limited data, which satisfies the low but not the moderate data threshold. No prescription is written, and no formal referral is placed, so risk is at the low level. Only one of three MDM elements is at moderate (the problem), so overall MDM is LOW, selecting 99213. Code 99214 requires two or more MDM elements at moderate; only the problem qualifies here. To reach 99214, the scenario would additionally need either moderate-risk management (such as a prescription) or moderate-level data (such as independent interpretation of an external test or extensive data review). Code 99215 requires high MDM; a breast mass without characterization does not yet represent a life-threatening condition.
4. Which CPT® code is reported for this established patient visit based on straightforward medical decision making?
   Answer: 99212 CPT® 99212 describes an established patient office visit with straightforward medical decision making (or 10-19 minutes of total time) — the correct code when the encounter involves one self-limited or minor problem, minimal or no data reviewed, and minimal management risk. A minor laceration managed with steri-strips, no prescription, and no data review satisfies all three elements at the minimal/straightforward level. Code 99213 requires low MDM; one self-limited problem without prescription drug management or meaningful data review does not meet the low threshold. Codes 99214 and 99215 require moderate and high MDM respectively, not applicable here. Straightforward MDM (99212 established, 99202 new) applies to encounters with single minor problems, minimal data, and no significant risk. Separately, the laceration management itself may be reportable with a wound repair code, with modifier 25 appended to the E/M if it is a significant, separately identifiable service.
5. Which CPT® code is reported for this initial hospital care visit based on moderate medical decision making?
   Answer: 99222 CPT® 99222 describes initial hospital inpatient care with moderate medical decision making (or 55-69 minutes of total time) — the correct code for an admission note that meets the moderate MDM threshold. Two stable chronic conditions being managed constitute moderate-level problem complexity. Reviewing at least one Category 1 data element (chest X-ray result) contributes to the data assessment. Initiating an IV antibiotic prescription constitutes moderate risk. Two of three MDM elements at moderate selects 99222. Code 99221 describes initial hospital care with low MDM (40-54 min), requiring only one stable chronic illness without significant management risk. Code 99223 requires high MDM (70-84 min), such as a life-threatening presentation with extensive data review and high-risk interventions; community-acquired pneumonia in a stable patient does not meet this threshold. Code 99231 is a subsequent hospital care code, not an initial admission code.
6. A new patient presents with 4 weeks of facial pressure, purulent nasal discharge, and headache. The physician cannot clinically exclude early orbital cellulitis from bacterial sinusitis based on examination alone. CT sinuses and a nasal culture are ordered, and an empiric antibiotic is prescribed. Which CPT® code is reported?
   Answer: 99204 CPT® 99204 describes a new patient office visit with moderate medical decision making (or 45-59 minutes of total time) — the correct code here because two of three MDM elements meet the moderate threshold. When sinusitis cannot be clinically distinguished from early orbital cellulitis, the problem represents a new problem with uncertain prognosis (the differential includes a potentially serious complication), which is the moderate-level problem category under the 2021 MDM table. Prescribing an empiric antibiotic constitutes prescription drug management, which is moderate-risk management. Two of three MDM elements at moderate — problem (new problem with uncertain prognosis) and risk (prescription drug management) — selects moderate MDM overall, supporting 99204. Code 99203 requires only low MDM; an uncertain diagnosis that includes the possibility of orbital cellulitis exceeds the straightforward acute uncomplicated illness threshold. Code 99202 is for straightforward MDM. Code 99212 is an established patient code; this is a new patient.
7. Under the 2021 E/M guidelines, 'total time' for office/outpatient visit level selection includes:
   Answer: All time related to the encounter on the date of service, including pre-service preparation, face-to-face time, and post-service work such as documentation and care coordination Under the 2021 AMA E/M guidelines, total time for office and other outpatient services is defined as all time personally spent by the reporting physician or qualified health professional on the day of the encounter, including: pre-visit preparation (reviewing prior records, test results, and correspondence); the face-to-face encounter with the patient; and post-visit activities (documentation, ordering tests, reviewing results, communicating with other providers, and care coordination). Time spent by clinical staff does not count toward the physician's total time unless the physician is personally supervising or participating. This expanded definition of time replaced the prior face-to-face only time standard, allowing physicians to account for the full scope of cognitive and coordinative work. When using time as the basis for level selection, the physician must document the total time spent and the activities performed.
8. An established patient arrives for a scheduled monthly B12 injection. The nurse reviews the patient's medication list, asks about any new symptoms, takes blood pressure and pulse, documents stable findings in the record, and administers the injection. The physician is not involved in this encounter and does not conduct a separate evaluation. Which CPT® code is reported?
   Answer: 99211 CPT® 99211 describes an office or other outpatient visit for an established patient that may not require the presence of a physician or other qualified health care professional — the appropriate code when clinical staff perform a minimal but distinct evaluation and management service without physician involvement. The nurse here performs a brief assessment (medication review, symptom check, vital signs, documentation) constituting a distinct, though minimal, E/M service beyond the injection itself. Code 99211 is the appropriate code for this kind of clinical staff encounter. Codes 99212-99215 require physician or qualified health care professional participation in medical decision making or personal time investment. Importantly, 99211 should not be reported for an injection alone without any accompanying E/M element; the brief nursing assessment documented here is what makes the E/M reportable. If no assessment is performed and only the injection is given, only the injection administration code should be reported.
9. Which CPT® code is reported for this subsequent hospital care visit based on moderate medical decision making?
   Answer: 99232 CPT® 99232 describes subsequent hospital care with moderate medical decision making (or 35-44 minutes of total time) — the correct code for an inpatient progress note that meets moderate MDM criteria. Two stable chronic illnesses constitute a moderate-level problem. Reviewing ordered lab or imaging results satisfies at least one Category 1 data element (limited data). Prescription antibiotic management constitutes moderate risk. Two of three MDM elements at moderate selects 99232. Code 99231 applies to low MDM (25-34 min), requiring only one stable chronic illness with minimal data and low risk. Code 99233 applies to high MDM (45-59 min), requiring a high-level problem such as severe exacerbation or life-threatening illness; this patient is recovering without complications. Code 99221 is for initial hospital care, not a subsequent visit. Subsequent hospital care codes (99231-99233) are used for daily progress notes after the initial admission.
10. An established patient with essential hypertension presents with persistently elevated blood pressure despite current medication. The physician reviews the patient's recent metabolic panel from this office, adjusts the antihypertensive prescription, and documents suboptimal blood pressure control. Which CPT® code is reported?
    Answer: 99214 CPT® 99214 describes an established patient office visit with moderate medical decision making (or 30-39 minutes of total time) — the correct code here because two of three MDM elements meet the moderate threshold. Hypertension with suboptimal control (a chronic illness with progression or inadequate management) constitutes a moderate-level problem. Adjusting the antihypertensive prescription constitutes moderate-risk management (prescription drug management). Two of three MDM elements at moderate — problem and risk — selects moderate MDM overall, supporting 99214. Code 99213 requires low MDM; a chronic condition with progression and a prescription adjustment exceeds the single-stable-condition model for low. Code 99212 requires straightforward MDM; this encounter involves prescription modification for a worsening condition, which is above straightforward. Code 99215 requires high MDM; no high-risk element (intensive toxicity monitoring, hospitalization decision, or life-threatening condition) is present. Reviewing in-office lab results adds one Category 1 data element, consistent with limited data (low), which, combined with two moderate elements in the other categories, still yields moderate overall MDM.
11. Which CPT® code is reported for this new patient office visit based on 65 minutes of total time?
    Answer: 99205 CPT® 99205 describes a new patient office visit with high medical decision making or 60 to 74 minutes of total time — the correct code for a new patient encounter where the physician documents 65 minutes of total time on the date of service. Code 99204 applies to 45-59 minutes for a new patient; 65 minutes exceeds this range. Code 99203 applies to 30-44 minutes. Code 99215 is an established patient code; this is a new patient requiring the 9920x series. When a new patient visit exceeds 74 minutes, code 99205 is still reported but prolonged services add-on code 99417 may be appended for each additional 15 minutes. For new patient visits, the time ranges are: 99202 (15-29 min), 99203 (30-44 min), 99204 (45-59 min), 99205 (60-74 min). The MDM for this encounter (poorly controlled type 1 DM, hypertensive urgency, and multiple active conditions from multiple prior providers) would also independently support 99205 via the high MDM pathway.
12. Which CPT® code is reported for this subsequent hospital care visit based on low medical decision making?
    Answer: 99231 CPT® 99231 describes subsequent hospital care with low medical decision making (or 25-34 minutes of total time) — the correct code for a routine, uncomplicated post-operative progress note addressing one stable condition, with no significant data review and low-risk ongoing management. One stable post-operative status (progressing as expected) constitutes a low-level problem; minor wound checks and no prescription changes satisfy low-risk management. Code 99221 is an initial hospital care code, not for subsequent daily progress notes. Code 99232 requires moderate MDM (35-44 min), such as management of multiple active problems or initiation of new prescriptions; routine post-operative monitoring does not meet this threshold. Code 99233 requires high MDM (45-59 min), indicating an unstable, severely exacerbated, or life-threatening condition. Routine post-operative daily progress notes for stable patients are classically reported with 99231.
13. A new patient reports that a prior provider mentioned an incidental thyroid nodule on a recent neck ultrasound. No imaging is available at this visit. The physician takes a focused history, orders a dedicated thyroid ultrasound, and recommends endocrinology follow-up. No prescription is written. Which CPT® code is reported?
    Answer: 99203 CPT® 99203 describes a new patient office visit with low medical decision making (or 30-44 minutes of total time) — the correct code here because only one of three MDM elements reaches the moderate level. The thyroid nodule is a new problem with uncertain prognosis (possible malignancy cannot yet be excluded), which classifies the problem at the moderate level under the 2021 MDM table. However, low MDM requires at least two of three elements to meet at least the low threshold, while moderate MDM requires at least two of three to meet the moderate threshold. With data at the low level (one test ordered = one Category 1 element = limited data, which satisfies the low but not the moderate data threshold) and risk at the low level (endocrinology referral without prescription drug management), only the problem element reaches the moderate threshold — the other two elements remain at low. Only one of three MDM elements is at moderate, so the overall MDM level is LOW, selecting 99203. Code 99204 requires two or more MDM elements at moderate; only the problem qualifies here. Code 99202 is for straightforward MDM; a new problem with uncertain prognosis exceeds straightforward.
14. Prescribing a drug that requires intensive monitoring for toxicity (such as clozapine, warfarin, or methotrexate) represents which level of risk in the 2021 MDM framework?
    Answer: High risk Under the 2021 AMA E/M MDM framework, drug therapy requiring intensive monitoring for toxicity is classified as HIGH risk. Examples include clozapine (mandatory CBC monitoring for agranulocytosis), warfarin (regular INR monitoring), methotrexate (liver and bone marrow toxicity monitoring), lithium (renal and thyroid monitoring), and certain chemotherapy agents. When high risk is present in the management category, that element alone satisfies the high-risk threshold; combined with one other MDM element at high level, the overall MDM is high. Minimal risk applies to over-the-counter medication management. Low risk applies to prescription drug management without intensive monitoring requirements. Moderate risk applies to prescription drugs generally, new prescription diagnoses, and minor surgery with risk factors. High risk specifically requires the intensive toxicity monitoring criterion or other high-risk actions such as hospitalization, DNR discussion, or decision not to escalate care due to poor prognosis.
15. Which CPT® code is reported for this new patient visit based on high medical decision making?
    Answer: 99205 CPT® 99205 describes a new patient office visit with high medical decision making (or 60-74 minutes of total time) — the correct code for a new patient encounter meeting high MDM criteria. Suspected subarachnoid hemorrhage is an acute illness posing an immediate threat to life (high problem). Independent interpretation of a CT angiogram from an outside provider (Category 2: 1 unique test) combined with discussion with an external physician (Category 3: 1 unique discussion) together satisfy the extensive data requirement (two data categories = extensive). The decision to arrange emergency hospital transfer constitutes high risk. Two or more MDM elements at high selects high overall MDM, requiring 99205. Code 99204 requires only moderate MDM; a life-threatening neurological emergency exceeds moderate. Code 99203 is for low MDM (new patient). Code 99202 is for straightforward MDM. High MDM for a new patient (99205) is selected by exactly the same MDM criteria as for an established patient (99215); the only difference is the new-vs.-established status.
16. Which CPT® code is reported for this new patient office visit based on straightforward medical decision making?
    Answer: 99202 CPT® 99202 describes a new patient office or other outpatient visit with straightforward medical decision making (or 15-29 minutes of total time) — the correct code for a new patient encounter in which the physician addresses one self-limited or minor problem, reviews minimal or no data, and the risk of complications is minimal. A single self-limited problem (acute URI), no data reviewed, and OTC management satisfy the straightforward MDM criteria. Code 99203 is used for low MDM (requiring at least one low-level problem element, limited data, and low risk); the encounter here does not meet the two-of-three low MDM threshold. Codes 99212 and 99213 are established patient codes; this is a new patient, requiring the 9920x series. Under 2021 E/M guidelines, history and examination no longer drive level selection; MDM or total time determines the appropriate level.
17. Which CPT® code is reported for this established patient office visit, supported by both high MDM and total time?
    Answer: 99215 CPT® 99215 describes an established patient office visit with high medical decision making (or 40-54 minutes of total time) — the correct code supported by both the MDM and total time pathways. Via MDM: an acute exacerbation of COPD with hypoxia posing a threat to bodily function is a high-level problem; the decision to hospitalize constitutes high-risk management. Two of three MDM elements at high selects high MDM, requiring 99215. Via total time: 52 minutes falls within the 40-54 minute range for 99215 for established patients. When both MDM and total time independently support the same code level, the documentation is strongly defensible; the physician may choose either pathway, but only one pathway is needed. Code 99214 requires only moderate MDM (30-39 min); the exacerbation and hospitalization decision exceed this threshold. Code 99212 is for straightforward MDM (10-19 min). Code 99213 is for low MDM (20-29 min).
18. Which CPT® code is reported for this hospital discharge management service?
    Answer: 99239 CPT® 99239 describes hospital discharge day management involving more than 30 minutes of the physician's total time on the date of discharge — the correct code when the discharging physician spends more than 30 minutes on all discharge-related activities including examination, counseling, discharge instructions, prescription management, referral coordination, and documentation of the discharge summary. Code 99238 describes discharge management of 30 minutes or less; the physician's documented time of 38 minutes exceeds this threshold, requiring 99239. Code 99235 describes same-day admission and discharge with moderate MDM or 70 minutes; the patient was not admitted and discharged on the same day. Code 99236 describes same-day admission and discharge with high MDM or 85 minutes. The sole differentiator between 99238 and 99239 is the time threshold: 30 minutes or less for 99238, more than 30 minutes for 99239.
19. Which CPT® code is reported for this emergency department visit?
    Answer: 99285 CPT® 99285 describes the highest-level emergency department visit, representing a presenting problem of high severity that poses an immediate threat to life or physiologic function, requiring immediate evaluation and management. Cardiac arrest with active CPR, emergent intubation, defibrillation, and pharmacologic resuscitation represents the most severe and resource-intensive ED presentation, clearly meeting the criteria for 99285. Code 99284 describes a high-severity problem not posing an immediate threat to life but requiring urgent evaluation; cardiac arrest poses an immediate life threat, requiring 99285. Code 99283 describes a moderately severe problem. Code 99282 describes a low-to-moderate severity problem with manageable risk. ED E/M codes (99281-99285) are not subject to the 2021 MDM revisions in the same way as office codes and are typically assigned based on the severity of the presenting problem and the intensity of resources required.
20. Which of the following is NOT one of the three elements of medical decision making under the 2021 E/M guidelines?
    Answer: Level of physical examination documented in the medical record Under the 2021 AMA E/M guidelines, medical decision making (MDM) is composed of exactly three elements: (1) number and complexity of problems addressed at the encounter; (2) amount and/or complexity of data reviewed and analyzed; and (3) risk of complications and/or morbidity or mortality of patient management. The level of physical examination is NOT a component of MDM. Physical examination must be performed and documented as medically appropriate, but it does not contribute to the determination of the MDM level or the E/M code selection under the 2021 framework. This represents a significant change from prior documentation guidelines (1995 and 1997), in which the number of examination organ systems or body areas directly drove the E/M level. Removing history and examination from the level-selection formula was intended to reduce administrative burden and focus credit on the cognitive work of diagnosis and management.
