Billing tips
Document exact start and stop times for the consultation to support the 21-30 minute time requirement
Impact: Missing time documentation is the #1 denial reason; proper time logs protect the full $51.43 reimbursement
Ensure the treating provider's written request for consultation is documented in the medical record before billing
Impact: Lack of documented request results in denials; request should specify clinical question and reason for consultation
Bill only once per 14-day period per patient, even if multiple discussions occur with the treating provider
Impact: CMS policy limits billing frequency; violating this can trigger audit and recoupment of $51.43 per occurrence
Do not bill 99448 if the consultation leads to a transfer of care or face-to-face encounter within 14 days
Impact: Use appropriate E&M code instead; billing both results in denial and potential recoupment of duplicate payment
Include both verbal discussion and written report in documentation; both components are required
Impact: Missing written report component may reduce reimbursement or cause denial; ensure EHR note or letter is filed
Verify that the patient has an established relationship with the treating provider before billing 99448
Impact: Code requires established patient; new patient consultations should use different codes or may be denied entirely
Common denials
Insufficient documentation of time spent on consultation (less than 21 minutes documented or no time stamps)
How to appeal: Submit detailed time log with start/stop times, breakdown of review time and discussion time. If time was 21-30 minutes but poorly documented, provide attestation and contemporaneous notes showing time spent. Consider policy references to CPT guidelines defining time-based codes.
No documented request from treating provider in medical record
How to appeal: Provide copy of consultation request (email, EHR message, phone note) from treating provider. Include clinical question posed and reason consultation was medically necessary. Reference CMS guidelines requiring interprofessional nature of service.
Billed more than once within 14-day period for same patient
How to appeal: If second consultation addressed entirely different clinical issue, provide documentation showing separate medical necessity. Otherwise, accept denial as policy-based. Consider bundling multiple discussions into single consultation with combined time if clinically appropriate.
Face-to-face encounter occurred within 14 days, making interprofessional phone/internet code inappropriate
How to appeal: If face-to-face visit was unplanned/emergent and distinct from telephone consultation, document separation and appeal with timeline. If visits were related, accept denial and ensure proper code (office visit CPT) was used for face-to-face encounter instead.

What is the difference between CPT 99448 and 99447?

The billing provider must have specialized knowledge relevant to the clinical question and must provide both verbal and written consultation.
How many times can you bill 99448 for the same patient?
CPT 99448 can be billed only once per patient per 14-day period, regardless of how many discussions occur with the treating provider during that time. Multiple consultations within 14 days should be combined into a single reportable service with total accumulated time documented.
What documentation is required to bill CPT 99448?
Required documentation includes: written request from treating provider, documented start/stop times totaling 21-30 minutes, record review details, clinical assessment using specialized knowledge, specific recommendations, written report to treating provider, and confirmation of verbal discussion. Missing any element risks denial.
Is CPT 99448 covered by commercial insurance?
Coverage varies by payer. While Medicare covers 99448 at $51.43, commercial payers may have different policies.
