Billing tips
Document total time on date of encounter when using time-based coding (60-74 minutes required)
Impact: Time-based coding can be easier to document than MDM and capture the $215.75 payment when extensive counseling/coordination occurs; underdocumented time leads to downcoding to 99204 ($168.31) - a $47.44 loss
Ensure medical decision-making meets high complexity criteria: extensive problems, extensive data reviewed/ordered, or high risk
Impact: Must meet 2 of 3 MDM elements at high level; failure results in downcoding to 99204 (moderate complexity) with $47.44 loss per visit
Verify patient is truly new (no professional service from same specialty in past 3 years)
Impact: Billing 99205 for established patient will be denied and downcoded to 99215 ($163.92), resulting in $51.83 recoupment plus potential audit flags
Bill non-facility rate ($215.75) for office settings and facility rate ($175.64) for hospital outpatient departments
Impact: Correct place of service (POS 11 vs 22) ensures proper payment; incorrect POS causes $40.11 underpayment or overpayment with recoupment risk
Support high complexity with documentation of prescription drug management, independent historian, or interpretation of tests
Impact: Specific data elements (ordering/reviewing external records, independent interpretation) strengthen high complexity justification and reduce audit vulnerability
Use problem-focused examination documentation rather than comprehensive system review when time is not the basis
Impact: 2021 guidelines eliminated comprehensive exam requirement; focused documentation saves physician time without reducing payment eligibility
Common denials
Insufficient documentation of medical necessity for high complexity visit
How to appeal: Submit appeal with detailed documentation showing 2 of 3 MDM elements at high level: number/complexity of problems (extensive), data reviewed/analyzed (extensive Category 1-3 elements), or risk of complications (high). Include medical records, diagnostic results, and treatment complexity rationale.
Patient not meeting new patient definition (seen within past 3 years by same specialty)
How to appeal: Verify patient status in practice management system; if truly new, submit records proving no encounter in past 36 months from same specialty/subspecialty. If established, accept recoding to 99215 and adjust future billing protocols.
Time not adequately documented when used as basis for code selection
How to appeal: Provide contemporaneous documentation showing total time on date of encounter (minimum 60 minutes for 99205). Include start/stop times or attestation of total time with breakdown of activities. Implement time-tracking template for future visits.
Downcoded to 99204 due to only moderate complexity MDM documented
How to appeal: Review documentation for underreported elements; many providers fail to document extensive data review or independent interpretation performed. Submit addendum clarifying data analyzed, external records reviewed, discussion with external providers, or independent visualization of imaging. Request payment difference of $47.44.
