How is E&M level selected for a cardiology visit in 2026?

Since 2021, office E&M codes (99202-99215) are selected by either medical decision making (MDM) or total time on the encounter date. History and physical exam no longer drive level selection though they remain required for clinical documentation. Cardiology visits are typically MDM-driven because problem complexity, data review, and risk components stack naturally with chronic cardiac conditions.

What counts toward MDM data review in cardiology?

Data review counts: reviewing prior test results (stress tests, echos, cath reports, ECGs), reviewing external notes from other providers, ordering new tests, independent interpretation of a test performed by another provider (not separately billed), and discussion with another physician or qualified health professional. Each element contributes to the data category of MDM per the 2021 CPT tables.

What visit qualifies as high-complexity MDM in cardiology?

High-complexity MDM (99205, 99215) requires two of three high-level elements: at least one chronic illness with severe exacerbation or acute illness posing threat to life or bodily function; extensive data review; and high risk of morbidity from additional testing or treatment. A cardiology visit for a patient with decompensated heart failure requiring hospitalization decision, with cath and echo review, and initiating high-risk medication typically qualifies.

When should time-based coding be used?

Time-based coding applies when the physician's total time on the encounter date exceeds the threshold for the desired level. Total time includes chart review, patient encounter, order entry, documentation, care coordination, and counseling — all performed on the encounter date. Time-based coding often benefits complex cardiology visits with extensive coordination that would otherwise underscore on MDM alone.

Cardiology E&M Coding: 2026 Level Selection

TL;DR

Cardiology E&M coding in 2026 follows the 2021 CPT revisions that eliminated history and physical exam from level selection for office visits (CPT 99202-99215). Level selection is driven by medical decision making (MDM) or by total time on the date of the encounter. MDM has three elements: problems addressed, data reviewed, and risk of complications or morbidity. Time-based selection uses the total minutes the physician spent on the encounter date on care activities. Cardiology visits frequently qualify for higher-level codes because complex chronic conditions, extensive data review (prior stress tests, echos, cath reports), and moderate-to-high risk medication management stack across the three MDM elements.

The 2021 E&M revision and what it changed

The 2021 CPT revisions restructured office and outpatient E&M coding (CPT 99202-99215). History and physical examination no longer drive level selection. Documentation of history and exam remains clinically necessary but does not determine which code level is billed. Level selection is by:

Medical decision making (MDM), or
Total time on the encounter date

Either pathway can qualify a code level; the physician selects whichever produces the appropriate level based on the encounter's actual complexity and time.

The MDM framework

MDM has three elements. Level selection requires meeting or exceeding the criteria for two of the three elements.

Element 1: Number and complexity of problems addressed

Minimal: one self-limited or minor problem
Low: two or more self-limited problems, or one stable chronic illness, or one acute uncomplicated illness
Moderate: one or more chronic illnesses with exacerbation, two or more stable chronic illnesses, one undiagnosed new problem with uncertain prognosis, one acute illness with systemic symptoms
High: one or more chronic illnesses with severe exacerbation or progression, one acute or chronic illness posing threat to life or bodily function

Cardiology chronic conditions (coronary artery disease, heart failure, atrial fibrillation, hypertension with complications) commonly qualify at the moderate or high level when exacerbation or progression is present.

Element 2: Amount and complexity of data

Data review counts across categories:

Reviewing prior test results (stress tests, echos, cath reports, ECGs, labs)
Reviewing external notes from other providers
Ordering new tests
Independent interpretation of a test performed by another provider (not separately billed by this provider)
Discussion with another physician or qualified health professional

The 2021 CPT tables specify how many elements from each category are required for each level. A cardiology visit reviewing a recent stress test, an outside cardiology consult note, and ordering a follow-up echo typically qualifies at moderate data complexity.

Element 3: Risk of complications and morbidity

Minimal: minimal risk
Low: low risk (OTC medications, minor procedures)
Moderate: moderate risk (prescription drug management, elective major surgery decisions, social determinants affecting diagnosis or treatment)
High: high risk (drug therapy requiring intensive monitoring, decision for major surgery with risk factors, decision not to resuscitate or de-escalate care)

Most cardiology medication regimens (anticoagulants, antiarrhythmics, guideline-directed heart failure therapy) qualify at moderate or high risk because they require monitoring for drug interactions, bleeding, arrhythmia effects, or renal function.

The time-based alternative

Time-based coding uses the total time the physician spent on the encounter date on care activities. Activities included:

Preparing to see the patient (chart review)
Obtaining and reviewing separately obtained history
Performing the medically appropriate examination
Counseling and educating the patient, family, or caregiver
Ordering medications, tests, or procedures
Referring and communicating with other health care professionals (when not separately reported)
Documenting clinical information in the electronic or other health record
Independently interpreting results (not separately reported)
Care coordination (not separately reported)

Time thresholds for 2026 (verify against current CPT for exact minute ranges as CMS finalizes annually):

99202: approximately 15-29 minutes total time
99203: approximately 30-44 minutes
99204: approximately 45-59 minutes
99205: approximately 60-74 minutes
99212: approximately 10-19 minutes
99213: approximately 20-29 minutes
99214: approximately 30-39 minutes
99215: approximately 40-54 minutes

Complex cardiology visits (heart failure exacerbation, arrhythmia management with device interrogation review, medication reconciliation across multiple providers) often exceed MDM-based level thresholds when calculated by time.

Common cardiology E&M patterns

New patient consultation for chest pain

Typical MDM: moderate complexity (undiagnosed problem with uncertain prognosis, moderate data review with prior testing, moderate risk from further diagnostic workup). Typical level: 99204.

Established patient with stable coronary artery disease and hypertension

Typical MDM: low to moderate (two or more stable chronic illnesses, minimal to low data review, moderate risk from prescription management). Typical level: 99213-99214.

Established patient with decompensated heart failure requiring hospitalization discussion

Typical MDM: high (chronic illness with severe exacerbation, extensive data review of recent studies, high risk from drug therapy requiring intensive monitoring). Typical level: 99215.

Post-procedure follow-up within 90-day global period

Bundled into the global payment. Not separately billable as E&M unless the visit addresses an unrelated problem (modifier 24 required with documentation).

Documentation supporting the selected level

Regardless of pathway (MDM or time), the encounter note should support the level selected:

If MDM-based: the note should clearly identify problems addressed, data reviewed, and risk factors influencing the visit
If time-based: the note should document total time and reflect the activities that occupied that time

Audit exposure concentrates on visits where the documentation shows a low-complexity encounter but the code billed is high-complexity. Consistent underdocumentation of complex visits leaves revenue on the table; consistent overdocumentation of low-complexity visits triggers audit review.
