What 99308 covers
Physicians, nurse practitioners, and physician assistants report 99308 for a subsequent evaluation of a resident in a skilled nursing facility or nursing facility. The encounter may address ongoing conditions, a new uncomplicated illness, or a change in care needs. Managing two stable chronic illnesses can support the problem element of low medical decision making (MDM), but the overall MDM level depends on at least two of its three elements. Work may include reviewing nursing observations, examining the resident, discussing care with facility staff, and updating treatment orders.
Select 99308 when the documented MDM is low or the reporting practitioner spends at least 20 minutes on qualifying work on the encounter date. Count the practitioner's face-to-face and non-face-to-face E/M work, including chart review, staff discussions, orders, and documentation; exclude facility staff time and time spent on separately reported services. Document the problems and management decisions supporting MDM or the total time supporting time-based selection. Medicare uses the facility rate for place of service (POS) 31, skilled nursing facility, and the nonfacility rate for POS 32, nursing facility.

99308 billing questions
How do I choose between this code and 99309?
Use 99308 for low MDM or at least 20 minutes of qualifying time. Use 99309 for moderate MDM or at least 30 minutes; prescription drug management alone does not establish moderate MDM.
Can a nurse practitioner bill this visit?
Yes. Nurse practitioners and physician assistants may report subsequent nursing facility visits under their own NPI, subject to Medicare and state scope-of-practice requirements.
What time counts toward the 20 minutes?
Count the reporting practitioner's qualifying work on the encounter date, such as reviewing records, examining the resident, speaking with nursing staff or family, entering orders, and documenting. Exclude facility staff time and time spent on separately reported services.
Which place of service do I use?
Use POS 31 for a skilled nursing facility and POS 32 for a nursing facility. Medicare uses the facility rate for POS 31 and the nonfacility rate for POS 32.
Can I bill this on the day the resident is discharged from the facility?
When the practitioner performs discharge-day management, report 99315 or 99316 for that work rather than 99308. Select the discharge code based on the time spent on discharge management.
Can prolonged service time be added to this level?
No. Medicare's prolonged nursing facility E/M service for subsequent care pairs with 99310 when its time requirements are met, rather than with 99308.
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.
