Billing tips
Document exact start and stop times to verify the 21-30 minute threshold; billing 99448 for 20 minutes requires downcoding to 99447
Impact: Incorrect time documentation results in $15-20 underpayment if downcoded or denial if overcoded
The consultant must prepare a written report that is placed in the patient's medical record and communicated to the treating provider
Impact: Missing written report is the #1 denial reason, resulting in 100% payment loss ($51.43)
Bill only once per 14-day period per patient for the same or similar issue; subsequent consultations within 14 days are bundled
Impact: Violating the 14-day rule results in automatic denial and potential audit flags
Ensure the treating provider documents the request for consultation and medical necessity in their own records
Impact: Audits frequently request both sides of documentation; lack of treating provider request increases recoupment risk by 40%
Do not bill 99448 if you have seen the patient in a face-to-face visit within the previous 14 days for the same condition
Impact: Violates CMS guidelines and results in denial; use different E&M code instead
Verify patient consent for interprofessional consultation is documented before billing
Impact: Some payers require documented patient consent; missing consent may trigger denial on audit
