11.2 Referring Patients: Competence, Medical Consultation, Professional Networks, and Referral Payments
Key Takeaways
ADA Code Section 2.B obliges dentists to seek consultation whenever the patient's welfare will be safeguarded or advanced by someone with special skills, knowledge, and experience.
California B&P § 650 makes offering or paying anything of value for patient referrals a crime, with up to one year in jail, a $50,000 fine, or both for a first conviction.
ADA Advisory Opinion 4.E.1 treats paying a marketing vendor a share of patient fees as prohibited fee splitting.
The AHA's 2021 statement limits antibiotic prophylaxis before dental procedures to patients at highest risk of infective endocarditis, such as those with prosthetic heart valves or previous endocarditis.
ADA's 2015 guideline says antibiotic prophylaxis is generally not recommended for patients with prosthetic joints before dental procedures.
The duty to refer (K2081)
Nonmaleficence includes "knowing one's own limitations and when to refer to a specialist or other professional" (ADA Section 2). Section 2.B obliges dentists to seek consultation, if possible, "whenever the welfare of patients will be safeguarded or advanced" by those with special skills, knowledge, and experience. The CDA Code, Section 9, adds that when care needs diagnostic or treatment methods beyond the dentist's scope of services, the dentist must inform the patient of all options and refer to a qualified provider.
Signals that a referral is due include:
- A procedure beyond your training or experience, such as a complex molar endodontic retreatment, an impacted canine exposure, or an implant in a site needing a sinus lift.
- A case that is not going as expected, such as persistent pain after endodontic treatment or a failing implant.
- A patient who needs sedation beyond your permit (Section 7.2).
- A suspicious lesion needing biopsy or specialist evaluation.
The law agrees: B&P § 125.6(b)(2) says a licensee is never required to perform a procedure they are not qualified to perform. Negligence and incompetence are grounds for discipline under § 1670.
Medical conditions that need information or referral (K2082)
A dentist must know when the medical history calls for a physician's input before treatment:
| Finding | Why it matters | Typical action |
|---|---|---|
| Severely elevated blood pressure (commonly cited at 180/110 mm Hg or higher) | Stroke and cardiac risk during stress and with epinephrine | Defer elective care; refer promptly, or urgently if symptomatic |
| Anticoagulant or antiplatelet therapy | Bleeding after surgery | Consult the prescriber; most minor oral surgery proceeds with local hemostasis. Never tell the patient to stop anticoagulants on your own |
| Antiresorptive or antiangiogenic drugs such as bisphosphonates or denosumab | Medication-related osteonecrosis of the jaw | Review history; coordinate with the physician; prefer non-surgical options where reasonable |
| Highest-risk cardiac conditions: prosthetic valves, previous endocarditis, certain congenital heart disease, cardiac transplant with valve disease | Infective endocarditis | AHA 2021 recommends prophylaxis only for these conditions, for procedures involving gingival manipulation, the periapical region, or perforation of the oral mucosa |
| Prosthetic joints | Worry about joint infection | ADA 2015 guideline: prophylaxis generally not recommended; consult the orthopedic surgeon when the history is complicated |
| Uncontrolled diabetes, immunosuppression, head and neck radiation | Healing, infection, osteoradionecrosis | Consult the physician before surgical care |
| Signs of systemic disease found in the mouth, such as suspected eating disorders, sleep apnea signs, or oral lesions of possible systemic origin | Early diagnosis | Refer to the physician, with the patient's consent |
Under ADA Advisory Opinion 4.A.1, decisions about treatment or referral for medically compromised patients must be made on the same basis as for other patients, not used as a pretext to avoid them.
A network of professional support (K2083)
Referring well requires relationships built in advance:
- Specialists in each discipline, including options in the patient's insurance network (CDA Section 9).
- Physicians for medical consultation, and an urgent care or emergency department for airway-threatening infections.
- Emergency coverage colleagues for after-hours care and for the dentist's absences (Section 11.5).
- Laboratories and pathology services for biopsies.
- Peer mentors or study clubs for case discussion, and the professional assistance resources of the dental society.
California law builds this idea into the RDHAP license: an RDHAP must document a relationship with at least one dentist for referral, consultation, and emergencies (B&P § 1930).
Offering compensation for referrals (K2084)
B&P § 650(a) makes it unlawful for a licensee to offer, deliver, receive, or accept "any rebate, refund, commission, preference, patronage dividend, discount, or other consideration" as compensation or inducement for referring patients. A first conviction can bring up to one year in county jail, a fine up to $50,000, or both (§ 650(i)). The Dental Practice Act adds § 1680(g) (commissions or rebates as unprofessional conduct) and § 1680(aa) (group advertising and referral services that violate § 650.2).
| Arrangement | Status |
|---|---|
| Paying a general dentist $100 for each patient referred | Illegal (§ 650) and unethical fee splitting (ADA 4.E) |
| Paying a marketing company a percentage of each new patient's fees | Fee splitting (ADA 4.E.1); lawful under § 650(b) only if the payment is for services other than referral and is commensurate with their value |
| Social-coupon deals | Allowed under § 650(g) only if the advertiser does not recommend or select the dentist, the fee is commensurate with the advertising, a consultation and full refund if ineligible are disclosed, and the regular price is shown (Section 3.1); see also CDA 11.A.1 |
| Internet directories and booking platforms that do not recommend or endorse a specific dentist | Not a referral payment (§ 650(h)) |
| Paying fair rent or fees for services, not tied to referrals | Allowed (§ 650(b)) |
Referral rewards to patients, such as gift cards for each friend referred, fit the broad language of "other consideration" and should be avoided. A thank-you note is always safe.
A general dentist finds a large, non-healing ulcer on the lateral border of a patient's tongue. He has never performed a biopsy. What is the ethical obligation?
Watch the lesion for six months before deciding
Attempt the biopsy to avoid inconveniencing the patient
Refer the patient promptly to a qualified provider, such as an oral surgeon or oral pathologist, for evaluation and biopsy
Tell the patient it is probably nothing to avoid causing anxiety
An oral surgeon offers a general dentist a $150 gift card for each implant patient referred. What is the correct analysis?
Accepting is lawful if the gift cards are reported as income
Accepting would be unlawful under B&P § 650 and unethical fee splitting under ADA Section 4.E
Accepting is lawful if the patients consent to the arrangement
Accepting is lawful if the total stays under $1,000 per year
A patient with a prosthetic knee replaced three years ago asks whether she needs antibiotics before her cleaning. Under the ADA's 2015 guideline, what is the general answer?
Antibiotic prophylaxis is always required for patients with any prosthetic joint
She must wait until the joint is five years old before any dental care
Antibiotic prophylaxis is generally not recommended for patients with prosthetic joints before dental procedures
Only chlorhexidine rinse is required, by California law
