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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

99310 billing questions

How do I decide between 99309 and 99310?

Use 99310 for high MDM or at least 45 minutes of qualifying time. Use 99309 for moderate MDM or at least 30 minutes when 99310's criteria are not met; a hospitalization decision can support high management risk but does not, by itself, establish high MDM.

Can 99310 be reported for a resident's first visit by our group?

Choose the code based on the service performed, not simply whether the resident is new to the group. Initial nursing facility codes 99304-99306 describe an initial evaluation; 99310 describes subsequent care.

What counts toward the 45 minutes?

Count the reporting practitioner's qualifying work on the date of service, such as examining the resident, reviewing records, coordinating care, ordering, and documenting. Exclude facility staff time and time spent on separately reported services.

How is prolonged time billed for Medicare with 99310?

When 99310 is selected by time and Medicare's threshold for prolonged nursing facility care is met, report G0317 for eligible additional 15-minute increments rather than CPT 99418. Document the total qualifying time.

Which place of service is used?

Use POS 31 for a skilled nursing facility stay and POS 32 for a nursing facility. Visits to assisted living residents fall under home or residence visit codes instead.

Can I bill 99310 and a discharge code for the same service?

No. When the service is nursing facility discharge management, report 99315 or 99316 according to the time spent on that service instead of 99310.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
