Supervision When the Dentist Leaves the Building
At 9:05 a.m. in a two-chair general practice in Manchester, the dentist is called to the hospital because his spouse was in a car accident. He tells the hygienist, 'I'll be back by noon-keep the schedule moving and text me if anything comes up.' The hygienist has three patients: Mr. R, 68, on warfarin with an INR drawn yesterday of 3.2, scheduled for periodontal scaling and root planing; Maya, 9, a new patient scheduled for sealants; and Ms. T, 34, who wants 'whitening before a wedding this weekend.' The front desk has already collected copays and tells the hygienist not to reschedule because 'the dentist always says yes.' The hygienist has current local anesthesia certification but no standing order for it. There is no other dentist on the premises. The office's written supervision policy is in a binder in the dentist's private office, which is locked.
1. Can the hygienist proceed with each of the three appointments? Analyze the supervision and scope issues for each patient.
Read the worked answer
Treat each patient separately because the dentist's absence changes what supervision is available.
- Mr. R: Scaling and root planing is periodontal treatment, and this patient is anticoagulated with an INR of 3.2. Even if SRP is otherwise within hygiene scope, it requires the dentist's clinical evaluation, a medical risk decision (possibly a physician consult), and whatever supervision level the Board requires for SRP. With no dentist on the premises and no written standing order, do not begin. Reschedule and contact the dentist.
- Maya: Sealants require a dentist's diagnosis that they are indicated and authorization to proceed. If the dentist examined her and the applicable supervision level permits, the hygienist may proceed; a new patient who has not been examined should not receive sealants on the front desk's say-so.
- Ms. T: Whitening is not automatically a hygiene procedure; it may be outside hygiene scope or require dentist authorization. A wedding deadline and tooth sensitivity are not clinical authorization. Do not start.
The governing principle is that when supervision or scope is unclear, the hygienist is personally accountable and must stop-not rely on office custom or the front desk's confidence.
2. The office manager says, 'Just bill Mr. R's SRP under the dentist's provider number; he authorized it last week.' How should the hygienist respond?
Read the worked answer
Refuse. Billing is not a workaround for supervision. Submitting a claim for SRP under the dentist's provider number when the dentist did not perform or supervise the service as required can be insurance fraud and a professional-conduct violation. 'He authorized it last week' does not satisfy a rule requiring the dentist's presence or evaluation at the time of a complex procedure, and it does not make the service billable. The hygienist should tell the manager in writing that she will not bill for services she is not permitted to perform, document the exchange, and ask the dentist to confirm the plan in writing. If the office pressures her to proceed, she should escalate to the dentist and consider seeking guidance from the Board. Fear of retaliation does not justify a false claim.
3. What should the hygienist document before noon, and what should she tell the patients?
Read the worked answer
Document contemporaneously and factually: the time the dentist left, the text or phone attempts, each patient's presenting issue, the decision made, who was notified, and the reschedule. Avoid charting 'dentist unavailable' as a criticism; chart 'dentist off premises for emergency; procedure deferred pending dentist evaluation.' For Mr. R, record the INR, the warfarin dose if known, and that the procedure was deferred for medical and supervision reasons. Tell patients a neutral truth: 'Dr. X was called away for an emergency; we need to reschedule this treatment so he can review it.' Do not disclose the nature of the emergency. Do not let the front desk tell patients the hygienist 'refused' care. If a patient insists, offer to have the dentist call.
