Cardiology, coding reference.

99214 is the workhorse of primary care and most outpatient subspecialties. Use it when at least one of these is true: two or more chronic problems with progression, treatment changes, or side effects; one undiagnosed new problem with uncertain prognosis; one acute illness with systemic symptoms; or prescription drug management at any complexity. Prescription drug management on its own satisfies the moderate-risk element, which is why straightforward chronic disease follow-ups with a med adjustment routinely clear the 99214 bar. Time-based alternative is 30 to 39 minutes of total time on the date of the encounter. Pick the method that supports the strongest note: encounters with prescription changes are usually cleaner under MDM; encounters with extensive counseling or care coordination are usually cleaner under time.

Select this level when at least two of the three MDM elements meet high complexity, or when qualifying total time reaches 40 minutes. A diagnosis, medication, or high-risk decision alone does not establish the overall level. For Medicare prolonged services with this time-selected base code, the first G2212 unit requires 69 minutes. Payers recognizing CPT 99417 use different thresholds.

Consider the ongoing responsibility for the patient's care: either a continuing focal point for needed services or ongoing care of a serious or complex condition. It is not automatic for a diagnosis or specialty.

Global EKG in your office: you own the machine and provide interpretation. Use 93005 if technical only, 93010 if interpretation only.

Professional component — you interpret a tracing acquired elsewhere (ED, inpatient, outside clinic).

Complete TTE with both spectral and color Doppler. The default outpatient TTE code.

Professional/technical split stress echo, typically in a hospital outpatient setting. In-office global use 93351.

Global in-office stress echo. Includes resting and post-stress TTE, supervision, interpretation.

Hospital outpatient or other setting where you supervise but don't own the equipment.

Interpretation of a stress test you supervised elsewhere.

48-hour Holter monitor performed in the office (you own the device).
