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

What 99310 covers

This is the highest level in the subsequent nursing facility E/M series. It covers a follow-up visit to a skilled nursing facility or long-term nursing facility resident after the initial evaluation. A practitioner might assess suspected sepsis, new respiratory failure, or a severe heart failure or COPD exacerbation and decide whether hospital transfer or a major change in treatment is needed. Attending physicians, geriatricians, nurse practitioners, and physician assistants commonly provide these visits during facility rounds.

Select 99310 when medical decision making is high or the reporting practitioner's qualifying time on the date of service reaches 45 minutes. High MDM requires two of three elements—problems, data, and management risk—at the high level; a hospitalization decision alone does not establish the overall level. Time may include examining the resident, reviewing records, coordinating with facility staff, and documenting, but excludes staff time and work counted toward another reported service. Document the supporting MDM elements or total qualifying time. If the visit is selected by time and Medicare's prolonged-service threshold is met, G0317 may be reported for eligible additional time.
