CPT 99215: Established Patient Office Visit, High Complexity

CPT 99215 is the highest-level office or outpatient visit for an established patient. It requires a high level of medical decision making, or at least 40 minutes of the provider’s total time on the date of the visit. It fits visits for severe flare-ups, threats to life or bodily function, and decisions such as hospital admission.

CPT 99215 description

99215 is an established patient office or other outpatient visit with a medically appropriate history and/or examination and a high level of medical decision making. When time is used to choose the level, 40 minutes must be met or exceeded. History and exam do not set the level.

99212	Straightforward	10 minutes or more
99213	Low	20 minutes or more
99214	Moderate	30 minutes or more
99215	High	40 minutes or more

High medical decision making: what supports 99215

Two of the three elements must reach high. This is the step up from 99214:

Element	Moderate (99214 / 99204)	High (99215 / 99205)
Problems addressed	1 or more chronic illnesses with exacerbation, progression or side effects; or 2 or more stable chronic illnesses; or 1 undiagnosed new problem with uncertain prognosis; or 1 acute illness with systemic symptoms; or 1 acute complicated injury	1 or more chronic illnesses with severe exacerbation, progression or side effects of treatment; or 1 acute or chronic illness or injury that poses a threat to life or bodily function
Data reviewed and analyzed	At least 1 of 3 categories: any 3 data items (notes, test results, tests ordered, independent historian); or independent interpretation of a test; or discussion with an external physician or other appropriate source	At least 2 of the same 3 categories
Risk of patient management	Moderate, for example prescription drug management	High, for example drug therapy requiring intensive monitoring for toxicity, a decision about hospitalization or escalation of care, or a decision about emergency major surgery

Typical 99215 visits

• Heart failure with a severe exacerbation, where the provider decides whether to admit the patient.
• Chest pain or another new symptom that could threaten life, with tests ordered, external records reviewed and the case discussed with a cardiologist.
• A patient on a drug that requires intensive monitoring for toxicity, with results reviewed and the dose managed.

Prescription drug management on its own is moderate risk, which supports 99214, not 99215.

Billing 99215 by time, and prolonged visits

Count the practitioner’s total time on the date of the visit, including:

• Preparing to see the patient, such as reviewing tests
• Getting or reviewing separately obtained history
• Performing a medically appropriate exam
• Counseling and educating the patient, family or caregiver
• Ordering medications, tests or procedures
• Referring and communicating with other professionals (when not separately reported)
• Documenting in the record
• Independently interpreting results (when not separately reported) and coordinating care

When time goes well past 99215, an add-on can be reported for each additional 15 minutes. CPT uses +99417. Medicare does not pay 99417 and uses its own code, G2212, which starts only after the 99215 time range is exceeded by 15 minutes: per the CMS Evaluation and Management Services guide (MLN006764) (opens in a new tab), 99215 plus one unit of G2212 needs 69 to 83 minutes of total time.

Documentation that supports 99215

• The severity of each problem, in words that show it is severe or threatens life or function
• Each data item: the notes reviewed, results reviewed, tests ordered, interpretations and discussions
• The high-risk decision and why, such as the reason for admission or the monitoring plan
• Or the total time, if time is used

Frequently asked questions

Is 99215 more likely to be audited?

Payers watch for providers whose share of 99215 is far above their peers. A well-documented 99215 is appropriate; the defense is a note that shows the severity and the decision.

What is the new patient equivalent of 99215?

99205, which also needs high MDM, or at least 60 minutes.
