What 99213 covers
This visit covers an established patient seen in an office, clinic, or other outpatient setting. Examples include follow-up for one stable chronic condition, such as controlled hypertension, or assessment of an uncomplicated urinary tract infection or sinusitis. Physicians, nurse practitioners, and physician assistants report it across primary care and specialty practices. The encounter may include a medically appropriate history and examination, but those activities do not set the visit level.
Select the level by medical decision making or total billing practitioner time on the encounter date. Low decision making requires two of three elements at the low level: problems addressed, data reviewed or analyzed, and management risk. Limited data may be met by an independent historian or the required combination of distinct record reviews, test reviews, and test orders; an over-the-counter treatment recommendation may indicate low risk. Alternatively, at least 20 minutes supports 99213, including qualifying review, documentation, and care coordination, but excluding clinical staff time. Document the problems and decision-making elements, or the practitioner's total time. A patient is established after professional services from the practitioner or a same-specialty, same-subspecialty group member within three years. Medicare assigns lower practice expense RVUs in a facility than in an office.

99213 billing questions
What separates 99213 from 99214 when billing by decision making?
99214 requires moderate decision making in two of three elements. Prescription drug management can indicate moderate risk, but another decision-making element must also reach moderate.
How much time is needed to bill 99213 based on time?
At least 20 minutes of billing practitioner time on the encounter date supports 99213; 30 minutes supports 99214 when selecting by time. Count qualifying face-to-face and non-face-to-face work, not clinical staff time or time spent on separately reported services.
Can 99213 be billed on the same day as a minor procedure?
Yes, if a significant, separately identifiable evaluation beyond the usual pre-procedure assessment is documented; append modifier 25 to 99213. The decision to perform the minor procedure alone does not justify a separate visit.
Can G2211 be added to 99213 for Medicare patients?
Yes, when the practitioner provides ongoing care as the continuing focal point for the patient's care or ongoing care for a single serious or complex condition. G2211 reflects visit complexity arising from that continuing relationship.
Are history and examination required to select 99213?
No. Perform and document them as medically appropriate; the level is selected by medical decision making or total billing practitioner time.
