What a curbside is for a PA
A curbside consult is a fast, informal, verbal question to a specialist for a quick sanity check. The specialist doesn't see the patient, doesn't document, and isn't taking responsibility. For a physician associate, that makes a curbside useful for narrow reasoning questions — not for anything the record needs to reflect.
As soon as the specialist's opinion belongs in the chart, the encounter has crossed into an eConsult (CPT 99451/99452) and should be documented and billed that way.
Curbside vs. supervising physician input
A specialist curbside doesn't replace the supervising or collaborating physician relationship your state requires. That relationship covers scope-of-practice; the specialist curbside covers a specialty question your SP may not have expertise in. Run both.
When curbside is right — and when to switch to eConsult
- Curbside — you mostly already know the answer, the case is straightforward, the plan won't change materially, and the specialist reasoning doesn't need to be in the chart.
- eConsult — the answer will change your plan, you'd otherwise refer, the reasoning should be defensibly documented, or the next clinician on the case needs the context.
For the coding mechanics, see CPT 99451 & 99452 explained.
Documentation guardrails
- Document your own reasoning, not the specialist's, when the encounter is a curbside.
- If you write "spoke with cardiology" you've attributed the opinion to the specialist and moved the encounter out of curbside territory — convert it to an eConsult and bill accordingly.
- Keep the SP relationship intact. A specialist curbside is a specialty-reasoning layer, not a scope-of-practice one.
Practical use in rural and community settings
Most PAs practicing in rural primary care, RHCs, and community hospitals end up using a mix of curbside and eConsult access every week. The curbside answers the "am I missing anything" question in minutes; the eConsult puts the specialist reasoning in the chart for the cases that need it. See specialist support for rural PAs for the setting-specific playbook.
Frequently asked
Can a PA ask a curbside consult?
Yes. A curbside is a fast informal verbal question to a specialist. It isn't documented and isn't billed. It's appropriate for a quick sanity check, not for specialist input the record should reflect.
Does a specialist curbside replace my supervising physician?
No. Your SP relationship (where state law requires one) satisfies scope of practice. A specialist curbside is a specialty-specific reasoning layer on top of that — both run in parallel.
When should I switch from a curbside to an eConsult?
When the answer will change your plan, when you'd otherwise refer, when the reasoning should be defensibly documented, or when the next clinician needs context. At that point the encounter has crossed into an eConsult and should be billed as one under CPT 99451 and 99452.
Can I document 'discussed with cardiology' in a curbside?
That language attributes the opinion to the specialist and moves the encounter out of curbside territory. If you want the specialist's reasoning in the record, run it as an eConsult so both sides document and bill appropriately.
