Billing tips
Document all three key components (comprehensive history, comprehensive exam, high MDM) as all are required for 99306, not just two
Impact: Prevents downcoding to 99305 ($137.63, a loss of $37.69) or 99304 ($102.61, a loss of $72.71)
Clearly document high complexity MDM using 2021 E/M guidelines: extensive problems addressed (high risk), extensive data review, or high risk of complications/morbidity
Impact: Ensures proper code level selection; inadequate MDM documentation is the leading cause of downcoding resulting in $37-72 loss per encounter
Bill 99306 only once per admission per physician; subsequent nursing facility visits use 99307-99310
Impact: Prevents automatic denials for duplicate initial visits; subsequent day visits pay $71-137 depending on complexity
Perform and document the initial comprehensive visit within 24-48 hours of admission per facility policy and payer requirements
Impact: Late visits may be denied or require appeals; timely documentation supports medical necessity and quality metrics
Include facility name, admission date, and reason for admission in documentation to establish this is the initial nursing facility encounter
Impact: Prevents confusion with subsequent care codes and supports audit defense; reduces denial rate by approximately 15-20%
Review and reconcile all medications, document medication management complexity, and include assessment of multiple organ systems
Impact: Medication reconciliation involving 5+ medications supports high MDM; comprehensive review supports level 99306 over lower levels
Common denials
Insufficient documentation of high complexity medical decision-making
How to appeal: Submit appeal with detailed audit worksheet showing high MDM elements: number/complexity of problems addressed (3+ chronic with exacerbation or 1 acute severe illness), amount/complexity of data reviewed (3+ categories), and risk level (prescription drug management + additional indicator). Include clinical notes demonstrating severity.
Service billed as initial visit when patient was previously seen in facility within 30 days
How to appeal: Provide documentation showing patient was formally discharged and readmitted as new admission, or that previous visit was by different specialty for unrelated problem. Include admission/discharge records and explanation of distinct episodes of care.
Missing comprehensive history or comprehensive examination documentation
How to appeal: Submit complete clinical note with highlighted sections showing comprehensive history (chief complaint, extended HPI 4+ elements, complete ROS 10+ systems, complete PFSH) and comprehensive exam (8+ organ systems documented). If elements present but not clearly formatted, submit with audit tool overlay.
Time-based billing attempted without appropriate counseling/coordination documentation
How to appeal: If billing based on time, document that >50% of the encounter time was spent on counseling/coordination, specify total time, and summarize counseling topics. Note: 99306 can use time as alternative to support level selection under certain circumstances, but key components method is more common.

How is CPT 99306 different from 99304 and 99305?
CPT 99306 requires high complexity medical decision-making along with comprehensive history and examination, while 99304 requires straightforward/low MDM and 99305 requires moderate MDM. The documentation and reimbursement differ significantly: 99304 pays $102.61, 99305 pays $137.63, and 99306 pays $175.32 under 2025 Medicare rates.
Can I bill 99306 for a patient I saw in the hospital who is now being admitted to a nursing facility?
Yes, you can bill 99306 for the initial nursing facility encounter even if you saw the patient in the hospital, as long as this represents a new admission to the nursing facility and you perform a comprehensive evaluation. The nursing facility admission is a distinct episode of care requiring initial comprehensive assessment in the new care setting.
What documentation is required to support high complexity MDM for 99306?
High complexity MDM requires documentation showing at least two of three elements: extensive number/complexity of problems (such as 3+ chronic illnesses with exacerbation or 1 acute severe illness), extensive amount/complexity of data reviewed (3+ categories including tests, independent historians, or external records), or high risk of complications (such as drug therapy requiring intensive monitoring or decision for emergency major surgery).
How many times can I bill CPT 99306 for the same patient?
You can bill 99306 only once per nursing facility admission per physician or same-specialty group. If the patient is discharged and readmitted to the nursing facility at a later date, you may bill 99306 again for the new admission. For ongoing care during the same admission, use subsequent nursing facility care codes 99307-99310.
What is the typical time associated with CPT 99306?
CPT 99306 is typically associated with 50 minutes of face-to-face time with the patient and/or family. However, code selection should be based primarily on the key components (history, examination, and medical decision-making) rather than time, unless more than 50% of the encounter is spent on counseling and coordination of care.
Can nurse practitioners and physician assistants bill CPT 99306?
Yes, nurse practitioners and physician assistants can bill CPT 99306 within their scope of practice and according to state regulations. When billing Medicare, NPs and PAs are typically reimbursed at 85% of the physician fee schedule rate unless billing incident-to a physician. The 2025 rate for NPPs would be approximately $149.02 (85% of $175.32).
