Washington Tribal Dental Therapist Chart Notes: Privacy Laws Checklist

This checklist focuses on dental therapists licensed under Washington law who work in tribal health settings. Washington rules expressly allow licensed dental therapists to practice at tribal federally qualified health centers (FQHCs), as well as FQHCs and look-alikes, and require them to follow the state dental-therapy rules. If a clinician instead practices under a separate tribal or federal credential, confirm which requirements apply to that role with the clinic’s compliance team or legal counsel. See WAC 246-819-010.

What privacy laws apply to tribal dental therapist chart notes in Washington?

The Washington Uniform Health Care Information Act (UHCIA), chapter 70.02 RCW, governs health care information held by covered Washington health care providers. The Act defines health care information broadly as identifiable information related to a patient’s health care and defines a health care provider to include a person authorized by Washington law to provide health care. See chapter 70.02 RCW.

HIPAA applies when the clinic or provider meets the federal definition of a covered entity or business associate. A dental provider is a HIPAA-covered health care provider when it transmits health information electronically in connection with a transaction for which HHS has adopted a standard. Tribal ownership alone does not establish whether HIPAA applies; check the clinic’s covered-entity status and any business-associate relationships. See HHS guidance on covered entities and business associates.

For Washington-licensed dental therapists, state dental-record and practice-plan rules apply in the settings identified by the state rules. Clinic policy, tribal requirements, federal program obligations, and applicable agreements may add procedures. Identify the clinic’s governing policies and follow any more protective requirements that apply.

What information must each dental chart note include?

Washington requires a dental therapist licensed under chapter 246-819 WAC to follow the dentist record-content rules. The clinical record must be legible, complete, and accurate; the overall patient record includes both clinical and financial records. See WAC 246-819-100 and WAC 246-817-305.

For each visit, document the date; relevant subjective complaints and objective examination findings; assessment or diagnosis; treatment plan; diagnostic aids such as images, radiographs, and test results; and a complete description of treatment or procedures provided. Record the patient’s current dental and medical history insofar as it may affect dental treatment.

Also document medications administered, prescribed, or dispensed—including the date, patient, medication name, dosage, amount, and refills—and referrals and communications with other health care providers. Note communications with the patient or the patient’s parent or guardian, including informed-consent discussions about risks, benefits, and alternatives; post-treatment instructions; treatment-related concerns or complaints; and termination of the provider-patient relationship when applicable. Retain a copy of each laboratory referral for the period specified in the rule.

How should entries identify the author and treating practitioner?

Each clinical entry must identify its author by signature, initials, or electronic verification. If treatment was provided, the record must separately identify who provided it. Where the person documenting the note and the treating practitioner differ, make both roles clear rather than leaving the treatment provider implicit. See WAC 246-817-305.

For electronic chart-note authentication, use the system’s electronic verification in a way that identifies the person making the entry. Do not erase or delete clinical entries. For electronically signed records, maintain an audit trail showing the date and time history of deletions, edits, and corrections. The rule does not prescribe a particular software product or require a supervising dentist to co-sign every note.

For a handwritten error, draw a single line through the incorrect information; date and initial the correction. Preserve the original entry so the record shows what was changed and when.

What must the dental therapist practice plan say about patient records?

A dental therapist must practice under a supervising dentist and a supervising dentist written contract, also called a practice plan contract. The contract must describe procedures for creating and maintaining records for patients treated by the therapist. It must also include a quality assurance plan that covers patient-care review, referral follow-up, and quality-assurance chart review. See RCW 18.265.060.

Make the plan operational: specify where notes are entered, who completes and authenticates them, how corrections and audit trails are handled, and how records are protected and made available to authorized care-team members. These practical details help implement the statutory recordkeeping requirements; they do not replace the required written contract or expand the therapist’s authorized scope of practice.

Washington rules also require the contract to be signed by the supervising dentist and therapist and submitted to the secretary at license renewal, with substantive revisions submitted within 30 days. See WAC 246-819-080.

How do record retention and patient access requirements apply?

Washington-licensed dental therapists must follow the same dental patient record retention and accessibility requirements as dentists. Keep patient records readily accessible for at least six years from the date of the last treatment. See WAC 246-819-110 and WAC 246-817-310.

Respond to a patient’s written request to examine or copy a record within 15 working days after receiving it. The record-access rule also requires compliance with chapter 70.02 RCW and applicable HIPAA privacy and destruction requirements. Patients may request an explanation of codes or abbreviations used in their information under RCW 70.02.080.

The six-year period is a minimum under the dental rule. Check for other applicable requirements, clinic policies, or pending matters before destroying records.

What chart-review steps belong in the quality assurance plan?

Washington requires the practice plan’s quality assurance plan to include patient-care review, referral follow-up, and a dental quality assurance chart review. The statute identifies those elements but does not prescribe a universal chart-sampling rate, review frequency, or scoring method. See RCW 18.265.060.

To make the plan usable, set out who performs reviews, how often reviews occur, how cases are selected, what findings are escalated, and how corrective actions are tracked. Review whether notes identify the author and treating practitioner, document examination and treatment, support care within the therapist’s authorized scope, record consent and medication details, and show referral follow-up and any required corrections.

Protect identifiable records used in review. Washington permits certain disclosures for quality assurance and related health care operations without patient authorization only on a need-to-know basis and with appropriate safeguards; an outside auditor may also have to agree in writing to limits on identification and further disclosure. See RCW 70.02.050 and RCW 70.02.200.

What limits apply to disclosure of dental health information?

As a general rule, a provider, an individual assisting in care, or a provider’s agent or employee may not disclose identifiable health care information without the patient’s written authorization unless a law permits or requires the disclosure. A valid health care information disclosure authorization must be written, dated, and signed; identify the information, patient, disclosing provider, and recipient; and include an expiration date or event. Keep the authorization or revocation with the relevant information. See RCW 70.02.020 and 70.02.030.

Washington law allows or requires some disclosures without authorization, subject to the applicable conditions. Examples include information needed by another provider for care, payment, certain health care operations or quality assurance, legally required public-health reporting, specified licensing or professional-conduct investigations, and disclosures needed to address a serious and imminent threat. For permitted need-to-know disclosures, share only what the recipient needs and use appropriate safeguards. See RCW 70.02.050 and RCW 70.02.200.

Do not treat a request, tribal affiliation, family relationship, or internal role by itself as permission to release a chart. Confirm the specific legal basis, recipient, and scope before disclosing information, and check for additional protections where the record contains specially protected information.

In short, keep each note complete and attributable, preserve records for at least six years after the last treatment, build required recordkeeping and review procedures into the practice plan, and disclose identifiable information only with valid authorization or under a specific legal exception.

FAQs.

Do Washington privacy laws apply to dental therapist chart notes at tribal clinics?

For a dental therapist licensed under Washington law and practicing at a tribal FQHC, Washington’s dental-therapy and patient-record rules apply. Those rules require compliance with dentist record-content and retention requirements. HIPAA applies if the clinic or provider meets the federal covered-entity or business-associate definition. A clinician practicing under a separate tribal or federal credential should confirm which requirements govern that role. See WAC 246-819-010, WAC 246-819-100, and HHS HIPAA guidance.

What must a dental therapist include in each chart-note entry?

Identify the note author by signature, initials, or electronic verification; identify the practitioner who provided treatment; and date the entry. Document relevant examination findings, assessment or diagnosis, treatment plan and care provided, along with applicable diagnostic aids, medications, referrals, consent discussions, instructions, and patient communications. See WAC 246-817-305.

How long must dental therapists retain patient records?

At least six years from the date of the last treatment, with records kept readily accessible. Dental therapists licensed under Washington’s chapter 246-819 WAC follow the dentist retention rule. See WAC 246-819-110 and WAC 246-817-310.

When may dental chart information be disclosed without patient authorization?

Only when a law permits or requires the disclosure and its conditions are met—for example, certain disclosures for treatment, payment, quality assurance or other health care operations, legally required public-health reporting, or a serious and imminent threat. Otherwise, obtain a valid written authorization that identifies the patient, information, recipient, disclosing provider, and expiration date or event. See chapter 70.02 RCW.
