6.3 Laws and Regulations Regarding Excessive Treatment and Over-Billing (BPC § 725)

6.3 Laws and Regulations Regarding Excessive Treatment and Over-Billing (BPC § 725)

In modern dental hygiene practice, clinical judgment must be exercised free from economic distortion, production quotas, or third-party reimbursement incentives. The delivery of unnecessary, excessive, or unindicated healthcare services harms patients physically and financially, inflates system-wide healthcare expenditures, and erodes public trust. To combat these practices, the California Legislature enacted rigorous statutory prohibitions governing excessive treatment and fraudulent billing.

The Statutory Prohibition of Excessive Treatment (BPC § 725)

California Business and Professions Code (BPC) § 725 establishes a comprehensive statutory prohibition against overtreatment across all healing arts licensees:

"Repeated acts of clearly excessive prescribing or administering of drugs or treatment, repeated acts of clearly excessive use of diagnostic procedures, or repeated acts of clearly excessive use of diagnostic or treatment facilities as determined by the standard of the local community of licensees is unprofessional conduct for a physician and surgeon, dentist, podiatrist, psychologist, physical therapist, chiropractor, or optometrist..."

California reinforces the § 725 rule with two dental-hygiene-specific provisions that candidates should be able to name. BPC § 1950.5(n) makes "the clearly excessive administering of drugs or treatment, or the clearly excessive use of treatment procedures, or the clearly excessive use of treatment facilities, as determined by the customary practice and standards of the dental hygiene profession" unprofessional conduct, and attaches the same criminal penalty — a fine of not less than $100 nor more than $600, imprisonment for not less than 60 nor more than 180 days, or both. BPC § 1956 reaches the office policy behind the conduct: it is unprofessional conduct to require, directly or through an office policy, or knowingly permit, the delivery of dental hygiene care that discourages necessary treatment, or that permits clearly excessive, incompetent, unnecessary, or grossly negligent treatment, or repeated negligent acts, as determined by the standard of practice in the community. Note the symmetry the exam likes to test: § 1956 penalizes under-treatment driven by office policy just as squarely as it penalizes over-treatment. Furthermore, BPC § 725 carries a distinct legal consequence: it creates dual legal liability involving both administrative discipline and criminal prosecution.

Specific Criminal Penalties Under BPC § 725

Under BPC § 725(b), any licensee who violates the statute is guilty of a misdemeanor:

• Punishable by a criminal fine of not less than one hundred dollars ($100) nor more than six hundred dollars ($600);
• Imprisonment in a county jail for a term of not less than 60 days nor more than 180 days; or
• Both such fine and imprisonment.

These criminal sanctions operate independently of administrative disciplinary actions initiated by the Dental Hygiene Board of California (DHBC), which may separately suspend or revoke the practitioner's license.

Clinical Manifestations of Overtreatment in Dental Hygiene

Excessive treatment in dental hygiene typically manifests in three distinct clinical areas:

1. Unwarranted Scaling and Root Planing (SRP)

Scaling and root planing (CDT codes D4341 and D4342) is an invasive therapeutic intervention designed to remove subgingival calculus, endotoxins, and diseased cementum. Clinical indications require objective diagnostic evidence of active periodontitis:

• Clinical attachment loss (CAL) confirmed by periodontal probing depths ≥ 4mm with active bleeding on probing (BOP);
• Subgingival calculus detectable by tactile exploration; and
• Radiographic confirmation of alveolar bone loss.

Performing 4 quadrants of SRP on a patient with generalized plaque-induced gingivitis (pseudopockets without attachment loss or bone resorption) constitutes clearly excessive treatment under BPC § 725. Subjecting healthy root surfaces to unnecessary root planing causes irreversible loss of cementum and dentin, leading to severe thermal hypersensitivity and increased susceptibility to root caries.

2. Indiscriminate Placement of Locally Delivered Antimicrobials

Locally delivered antimicrobials (such as minocycline hydrochloride microspheres [Arestin], CDT code D4381) are therapeutic adjuncts indicated strictly for localized, persistent or recurrent deep pockets (≥ 5mm) with bleeding upon probing following thorough mechanical debridement. Routinely placing antimicrobials across entire arches or in healthy 3mm to 4mm sulci without localized clinical justification—frequently driven by corporate production incentives—violates BPC § 725 and professional standards.

3. Excessive Diagnostic Radiographs

Exposing radiographic surveys must be based on individualized clinical examinations and historical risk assessments pursuant to FDA/ADA radiographic guidelines. Exposing full-mouth series (FMX) or panoramic radiographs at arbitrary calendar intervals (e.g., "every 3 years regardless of symptoms") without diagnostic justification violates BPC § 725 by subjecting patients to unnecessary ionizing radiation.

The Counterpart Danger: Substandard Under-Treatment

While overtreatment is illegal, delivering substandard under-treatment (commonly termed "supervised neglect") is equally unlawful under California law. When a patient diagnosed with generalized Stage III periodontitis demands "just a regular routine cleaning" (CDT D1110) because their insurance only covers cleanings or they wish to avoid out-of-pocket costs, the dental hygienist faces a severe legal trap:

• Gross Negligence and Incompetence: Performing a superficial coronal polish in the presence of active periodontitis provides no therapeutic benefit, leaves toxic subgingival pathogens undisturbed, and allows irreversible bone loss to progress silently.
• Legal Duty to Refuse: A patient cannot legally consent to substandard treatment. Performing a prophylaxis on active periodontitis misleads the patient into believing their oral disease is managed.
• Proper Protocol: The clinician must refuse to deliver substandard care, educate the patient on the hazards of non-treatment pursuant to Truman v. Thomas (1980) 27 Cal.3d 285, execute an informed refusal document, and offer safe alternatives or periodontist referral while providing emergency coverage to avoid abandonment.

Third-Party Billing and Insurance Fraud

Billing fraudulent claims for dental hygiene services violates both civil contracts and state criminal laws (California Penal Code § 550 and Insurance Code § 1871.4):

• Upcoding: Billing a routine adult prophylaxis (D1110) as quadrant scaling and root planing (D4341) to obtain higher insurance reimbursement.
• Unbundling: Disaggregating unified procedural components into separate codes to bill multiple fees for what should be a single global service.
• Date and Provider Misrepresentation: Altering treatment dates to fit insurance eligibility windows, or listing the dentist as treating provider when the hygienist performed the service unsupervised.
• Routine Copayment Forgiveness: Routinely waiving copayments or deductibles without notifying the insurer, which falsely inflates the actual fee charged.

Employment Pressures, Professional Autonomy, and Whistleblower Rights

In corporate or high-volume private practice, dental hygienists may face pressure from practice managers or employer dentists to meet monthly production quotas by overtreating patients or upcoding claims.

• Individual Licensure Accountability: In California, a professional dental hygiene license is personal. "I was only following the employer's policy" or "the office manager directed me to bill this code" is never a legal defense before the DHBC or in a criminal proceeding.
• Duty to Refuse: An RDH has an affirmative legal obligation to refuse unlawful directives that compromise patient safety or commit billing fraud.
• Whistleblower Protections: Under California Labor Code § 1102.5, an employer cannot retaliate, demote, suspend, or terminate an employee for disclosing information to a government agency (such as the DHBC or Department of Insurance) or refusing to participate in an activity that violates state or federal statutes.
