Billing tips
Document the specific moderate complexity MDM elements: at least three problems addressed, moderate data reviewed (such as independent review of external records or ordering tests), or moderate risk to patient
Impact: Proper MDM documentation prevents downcoding to 99308, which pays $30-40 less per visit
Bill only once per calendar day per provider, even if multiple visits occur; combine all face-to-face time and select the highest level of service supported
Impact: Prevents denials for duplicate billing and ensures maximum appropriate reimbursement
For 2025, time-based selection is allowed if total time on date of encounter is documented; 99309 requires 30-39 minutes of total time spent on the patient's care that day
Impact: Time documentation provides alternative pathway when MDM is borderline, potentially capturing full $104.16 reimbursement
Avoid billing 99309 within the SNF Part A global period unless the service is unrelated to the condition for which the patient was admitted to the SNF
Impact: Services related to SNF admission during Part A stay are bundled; unbundling causes recoupments
For patients with Medicare Part B only (not Part A SNF benefit), 99309 is billable for all medically necessary visits without frequency limitations
Impact: Ensures consistent monthly revenue stream for long-term care management averaging $400-500 per patient monthly
Document any orders reviewed, test results interpreted, or communication with other healthcare professionals to substantiate moderate complexity data review
Impact: Strengthens audit defense and supports the 3.22 RVU differential between 99308 and 99309
Common denials
Medical necessity not established - documentation does not support moderate complexity MDM
How to appeal: Submit appeal with detailed explanation of MDM elements present: number and complexity of problems addressed, amount/complexity of data reviewed with specific examples, and risk assessment. Reference 2021 E/M guidelines grid showing moderate level met.
Service included in SNF Part A consolidated billing - bundled payment denial
How to appeal: Verify patient's Part A status on date of service. If Part B only, submit remittance showing no Part A coverage. If service was unrelated to SNF admission diagnosis, append modifier and provide documentation showing distinct condition managed.
Frequency limitation - multiple visits per day by same provider
How to appeal: Demonstrate that only one E/M service was billed per calendar day. If visits were by different providers in same group, clarify in appeal and reference individual NPI and specialty differences if applicable.
Insufficient documentation - visit note does not meet required elements
How to appeal: Submit complete medical record showing interval history since last visit, examination findings, assessment of conditions, and plan of care. Highlight MDM components and time spent if using time-based coding. Add attestation statement if elements are present but not clearly delineated.
Frequently asked questions
What is the Medicare reimbursement rate for CPT 99309 in 2025?
The 2025 Medicare national average reimbursement rate for CPT 99309 is $104.16 for both facility and non-facility settings. This is based on 3.22 total RVUs (1.92 work RVU, 1.17 PE RVU, 0.13 MP RVU) multiplied by the 2025 conversion factor of 32.3465.
How often can you bill CPT 99309 for nursing facility patients?
For Medicare Part B patients, 99309 can be billed as frequently as medically necessary and documented. CMS does not impose specific frequency limits, though medical necessity must be established for each visit. For patients under SNF Part A consolidated billing, services related to the SNF stay are bundled and not separately billable.
What is the difference between CPT 99309 and 99308?
CPT 99309 requires moderate complexity medical decision-making and typically 30 minutes, while 99308 requires low complexity MDM and typically 20 minutes. The key distinction is the MDM level: 99309 involves more complex problems, more extensive data review, or higher risk management compared to 99308.
Can nurse practitioners bill CPT 99309 in nursing facilities?
Yes, nurse practitioners and physician assistants can bill CPT 99309 for nursing facility visits within their scope of practice and state regulations. Medicare reimburses NPs and PAs at 85% of the physician fee schedule rate ($88.54 for 99309 in 2025) when billing under their own NPI.
What documentation is required to support CPT 99309?
Documentation must include interval history, problem-focused examination, and moderate complexity medical decision-making meeting 2 of 3 criteria: moderate number/complexity of problems addressed, moderate amount/complexity of data reviewed, or moderate risk of complications. Alternatively, documentation of 30-39 minutes total time spent on the patient's care that day supports 99309.
Can CPT 99309 be billed with other E/M codes on the same day?
No, only one E/M service per provider per patient per day is allowed in nursing facility settings. If multiple encounters occur, combine the work and bill the single highest appropriate level. However, 99309 can be billed with procedures or other non-E/M services when modifier 25 is appropriately applied.
Is CPT 99309 covered for telehealth nursing facility visits?
Telehealth coverage for nursing facility visits varies by payer and current regulations. During the COVID-19 public health emergency, Medicare allowed telehealth for these services with modifier 95 or GT. Check current CMS telehealth policies and state regulations, as permanent coverage rules continue to evolve post-PHE.
