    Curbside consults for nurse practitioners: when to use one, when to switch to eConsult

    A curbside is a fast verbal sanity check with a specialist. Here's how NPs use it without over-attributing the opinion in the chart.

    TL;DR

    A curbside is an informal verbal question to a specialist; it isn't documented and isn't billable. For NPs, a curbside is right when you mostly already know the answer. If the specialist's reasoning will change your plan or belongs in the chart, convert to a documented eConsult (CPT 99451/99452). Curbside access sits on top of your collaborating physician relationship — it doesn't replace it.

    What a curbside consult is (and isn't) for an NP

    A curbside consult is a fast, informal, verbal question to a specialist. The specialist doesn't see the patient, doesn't document, and isn't taking responsibility for the case. For a nurse practitioner, a curbside is a sanity check — "am I missing anything obvious?" — not a specialty opinion of record.

    The moment the specialist's opinion becomes attributable in the chart, the encounter is no longer a curbside. It's an eConsult, and it should be documented and billed as one under CPT 99451 and 99452.

    When a curbside is the right tool

    • You mostly already know the answer and want a fast confirm.
    • The question is narrow and doesn't require chart context.
    • The plan won't change substantially based on the answer.
    • You don't need the specialist reasoning in the record.

    When to convert it into an eConsult

    • The specialist's input is going to change your plan.
    • You'd otherwise refer the patient out.
    • You want the reasoning defensibly documented.
    • The next clinician will need context you don't want to re-explain.

    For the mechanics, see CPT 99451 & 99452 explained and how an eConsult actually gets billed.

    Documentation guardrails for NPs

    • Document your own reasoning, not the specialist's. Language like "spoke with cardiology" attributes the opinion and moves the encounter out of curbside territory.
    • If the specialist input is going in the chart, run the encounter as an eConsult so both sides document and bill appropriately.
    • Keep your collaborating physician relationship intact. A curbside or eConsult with an outside specialist doesn't replace the CP role your state requires.

    Curbside plus collaborating physician

    Curbside access is a specialty-reasoning layer on top of your CP relationship, not a replacement for it. Your CP satisfies the state-scope requirement. The specialist curbside answers the specialty-specific question your CP may not have expertise in. Both are running at the same time; neither cancels the other. For the CP side, see the NP collaborating-physician guide.

    Frequently asked

    Can a nurse practitioner ask a curbside consult?

    Yes. A curbside is a fast informal verbal question to a specialist. It doesn't create a specialist-of-record relationship, isn't documented, and isn't billed. It's the right tool for a quick sanity check, not for specialist input the record should reflect.

    How is a curbside different from an eConsult?

    A curbside is verbal and undocumented; the specialist doesn't see the patient or write anything. An eConsult is asynchronous and documented — the specialist returns a written opinion that becomes part of the chart and is billable under CPT 99451 (specialist) and 99452 (treating provider) when time and documentation thresholds are met.

    Does a specialist curbside replace my collaborating physician?

    No. Your CP relationship (where state law requires one) satisfies scope of practice. A specialist curbside is a specialty-reasoning layer on top of that — the two run alongside each other.

    When should I convert a curbside into an eConsult?

    When the specialist input changes your plan, when you'd otherwise refer the patient out, when the reasoning should be defensibly documented, or when the next clinician on the case will need context you don't want to re-explain.
