Many clinicians are already doing the work of an eConsult: reviewing a case, gathering the right clinical context, asking a specialist for input, incorporating that recommendation into the care plan, and documenting the next steps for the patient.
The question is whether the practice is getting paid for that work.
For practices that bill insurance, eConsults may create reimbursement opportunities in two ways:
First, through interprofessional consultation codes when payer rules are met. Second, by supporting higher E/M complexity when the specialist input is part of the same-day medical decision making for a patient visit.
1. eConsults may be billable as interprofessional consultations
CMS recognizes CPT codes 99446–99449, 99451, and 99452 for interprofessional consultations conducted by phone, internet, or EHR, where a treating clinician requests specialist input without the patient seeing the specialist face to face. (CodingIntel)
The structure usually looks like this:
The consulting specialist may bill:
- 99446: 5–10 minutes, verbal and written report
- 99447: 11–20 minutes, verbal and written report
- 99448: 21–30 minutes, verbal and written report
- 99449: 31+ minutes, verbal and written report
- 99451: 5+ minutes, written report only
The treating or requesting clinician may bill:
- 99452: 16–30 minutes spent preparing for the referral and/or communicating with the consultant
These codes are designed for clinicians who can independently bill E/M services, including physicians and other qualified health care professionals. (Highmark)
2. Specialist input can also support E/M complexity
There is another important billing angle: eConsults can support the complexity of a same-day E/M visit.
Office and outpatient E/M code selection can be based on either total time or medical decision making. MDM is determined by the number and complexity of problems addressed, the amount and/or complexity of data reviewed and analyzed, and the risk of patient management decisions. Two of the three elements generally need to be met for a given MDM level. (ACAAI Member)
When a clinician reviews outside information, discusses management with another clinician, or incorporates specialist guidance into the patient’s care plan, that work may support the data and/or risk elements of MDM, depending on the facts of the encounter and payer rules. The AMA’s E/M FAQ notes that review of materials from a unique source can count toward MDM, and examples from specialty coding guidance show that discussion with another provider can contribute to higher MDM when the rest of the case supports it. (American Medical Association) (Infectious Diseases Society of America)
In practical terms: if a primary care clinician sees a patient, uses an eConsult the same day to clarify diagnosis or management, and documents how the specialist input affected the plan, that work may support a higher-complexity E/M code when appropriate.
That does not mean every eConsult automatically increases the visit level. It means the work should not be invisible. If it meaningfully affects medical decision making, it should be documented.
3. Documentation matters
To support billing, documentation should clearly show:
- The clinical question being asked
- The patient-specific information reviewed
- The specialist’s written recommendation
- The time spent, when billing time-based interprofessional consultation codes
- The requesting clinician’s work, when billing 99452
- How the recommendation affected diagnosis, treatment, risk assessment, medication decisions, referrals, or follow-up
For Medicare, patient or family consent must be obtained and documented for interprofessional consults because the patient is not present and cost-sharing may apply. Commercial payer consent rules may vary. (ACAAI Member)
4. Know when not to bill
There are important limitations.
Interprofessional consultation codes generally should not be used when the communication is simply arranging a transfer of care or scheduling a face-to-face specialist visit. They also may not apply if the patient has recently seen the consultant face to face or is scheduled for a related face-to-face visit soon after. Some payer guides also include frequency limits, such as not reporting consultant codes more than once per patient within seven days and not reporting 99452 more than once per patient within 14 days. (Highmark)
Payer policies vary, and practices should check their contracts, Medicare Administrative Contractor guidance, commercial payer policies, and billing team workflows before submitting claims.
5. The practical takeaway
For practices that bill insurance, eConsults can help ensure clinicians are paid for work they are already doing: coordinating care, reviewing patient information, consulting specialists, and making more informed treatment decisions.
If this all sounds like a lot to manage, you can work with Thea Health instead. We help pull the documentation together, organize the specialist recommendation, and support a cleaner record for the practice. And if you do not have the right specialist locally, Thea Health gives you access to more than 135 subspecialties.
This is not billing, coding, or legal advice. Thea Health is not a billing company, and practices should work with their billers, coders, compliance teams, and payer representatives to determine what is appropriate for their specific situation.
