Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 99203 covers

A new patient has received no professional services from a physician or other qualified health care professional of the same specialty and subspecialty in the group during the preceding three years. Physicians, nurse practitioners, and physician assistants perform this office or outpatient evaluation in clinics and hospital outpatient departments. Presenting problems can include an uncomplicated acute illness or injury or a stable chronic condition, but the diagnosis alone does not establish low medical decision making (MDM). The clinician assesses the problem and develops a care plan.

Report 99203 when the visit meets low MDM or the physician's or qualified professional's total time on the encounter date reaches 30 minutes. MDM requires two of three elements at the low level: problems addressed, data reviewed and analyzed, and management risk. Count face-to-face and eligible non-face-to-face work, such as record review and documentation, but not clinical staff time or separately billed services. Record a medically appropriate history and examination when indicated; neither determines the level. If a minor procedure occurs that day, append modifier 25 only for a significant, separately identifiable E/M service beyond the usual procedure work.
