When an Associate Dentist Leaves: Patients, Records and Notice

Start with the contract, not the state board.

The notice a departing associate owes you is a term of your associate agreement: how much notice they must give, what happens to patients mid-treatment while it runs, who holds the records, and who buys tail.

Read it before the exit conversation, because it settles the notice, records and tail questions below.

The records clause is the one you most want settled at hire rather than at exit.

Texas shows why: dental records there are the sole property of the dentist who performed the service, but ownership of original records may be transferred under the board's rule, and a transfer-of-records agreement may be made at any time in an employment relationship and can cover future dental records.

In other words, an associate agreement in Texas can assign record ownership to the practice owner — in writing, at the start of the relationship, so the departure never has to argue about it.

Settle tail coverage in the agreement the same way, for the same reason; we come back to it below.

And if this is the second associate resignation in a year, the contract is the symptom rather than the disease — our guide to associate retention covers the keep-side of the problem.

Patient notification is the step of a departure with a rulebook of its own: state dental board rules, state statutes and the American Dental Association's ethics code — and it is state-specific.

The state law this page carries is board rules from Texas and Florida plus statutes in California, Maryland and Colorado.

Rules in other states were not part of this page's research, so treat them as unknown until you check with your own board.

The baseline is the ADA's Code of Professional Conduct: once a dentist has undertaken a course of treatment, the dentist should not discontinue it without giving the patient adequate notice and the opportunity to obtain the services of another dentist.

The Code is an ethics code for ADA members (revised to March 2023), not state law — the state law below is what carries legal force.

• California. Business and Professions Code 1680(u) makes it unprofessional conduct for a licensee to abandon a patient — without written notice that treatment is to be discontinued, and before the patient has had ample opportunity to secure another dentist or hygienist.
• Texas. Board rule 22 TAC 108.5 bars abandoning a patient without reasonable cause: once treatment is undertaken, the dentist must give at least 30 days' written notice of intent to discontinue it, hand-delivered or sent by certified mail, return receipt requested. The notice must describe the patient's current status and treatment plan, present and future needs, and the consequences of non-treatment, recommend continuing care with another dentist — and the dentist stays reasonably available for emergency treatment for up to 30 days from the notice date.
• Florida. When a dentist terminates practice or relocates outside the local telephone directory service area, a notice must be published — in a newspaper or prominently on a website, weekly for 4 weeks — within one month, telling patients how to obtain copies of their records.
• Maryland. On a patient's request, the employer of a licensed direct-patient-care employee earning over $350,000 must provide notice of the new location where the former employee will be practicing.
• Colorado. SB 25-083 deems a covenant to restrict the practice of dentistry if it prohibits or materially restricts a provider from telling patients they treated about their continuing practice, their new contact information, or the patient's right to choose a provider — and Colorado voids non-competes and customer non-solicits restricting the practice of dentistry regardless of the provider's income, for covenants entered into or renewed on or after the act's effective date. That is Colorado's rule; the states this page did not research were not checked, so whether a muzzled goodbye puts a covenant at risk elsewhere is a question for your state's law.

For your own letters, the required contents on the Texas list — status, plan, future needs, consequences of non-treatment, a recommendation to continue care, emergency availability — are a sound outline anywhere.

What you cannot borrow is another state's deadline.

Record custody is decided by state rule and by your contract, so fix both in writing at the exit.

In Texas, a dentist who leaves a location or practice — whether by retirement, sale, transfer, termination of employment or otherwise — must maintain their dental records, make a written transfer of records to the succeeding dentist, or make a written agreement for the maintenance of records, and must notify the State Board of Dental Examiners in writing within 15 days of a transfer or maintenance agreement.

If your departing associate owns their charts under your state's rule, the written transfer or maintenance agreement is the document that leaves the charts — and the continuity of care — with the practice.

Texas also shows what holding the records obliges a dentist there to: keeping them at least five years from the last treatment — for a minor, until age 21 or five years, whichever is longer — furnishing requested copies within 30 days, and not withholding them over a past-due account.

Florida reaches the same place from the other side.

A practitioner terminating or relocating a practice there must retain the records personally or through an authorized agent — the rule names a successor-owner dentist as a possible agent — and make them available to patients for 4 years from the date the patient was last examined or treated.

That agent language is how a practice ends up as custodian: the departing dentist names you.

The federal clock that applies everywhere HIPAA does is the patient's right of access.

A covered entity must act on a records request no later than 30 days after receiving it, with one extension of up to 30 more days if it gives the patient a written reason within the first 30 — and it may charge only a reasonable, cost-based fee for copies.

Your practice's own permissions do not change with the departure, either: a covered entity may use or disclose protected health information for its own treatment, payment and health care operations, and the ADA's Code separately calls for providing, under applicable law, information that will benefit a patient's future treatment when a patient or another dental practitioner asks.

For every state this page did not research, custody is an open question — check your board's rule before you sign the custody agreement.

Before the associate's last day, list every patient with a treatment plan the associate started but did not finish.

Someone has to complete that work — you, another associate, or a referral — and the ADA's Code says a dentist who has undertaken a course of treatment should not discontinue it without adequate notice and the opportunity to obtain another dentist.

Concretely: call the mid-treatment patients, rebook them with the clinician who will finish, and document the handoff in the chart so the next clinician knows where the plan stands.

Who collects the receivable on the associate's work is a term of your associate agreement — check it before the last day.

Either way, patients owe for work already delivered, and that is exactly why records cannot become a collections tool.

Texas bars withholding records over a past-due account.

Florida bars conditioning copies on payment of an unpaid or disputed fee, with copies generally due within 30 days.

The ADA's advisory opinion 1.B.1 says records useful to future treatment should go to the patient or the new dentist gratuitously or for nominal cost, whether or not the patient's account is paid in full.

Run the accounts-receivable and treatment-plan reports the day notice lands.

Unfinished plans and unpaid balances are both part of what the departure costs you, and both belong in the exit conversation — not discovered a quarter later.

Federal law does not require you to hand a departing employee their final paycheck immediately — faster deadlines are state law.

The states this page sourced:

• California. If you discharge the associate, all earned and unpaid wages are due and payable immediately. If the associate quits without a fixed-term contract, wages are due within 72 hours — or at the time of quitting if they gave at least 72 hours' previous notice.
• Texas. A discharged employee must be paid in full no later than the sixth day after discharge; an employee who leaves any other way must be paid by the next regularly scheduled payday.

The deadline table for every role, in the states this site verified, is in our final paycheck rules guide.

For a production-based associate, the final check is where the reconciliation happens: draw against production, production actually delivered, collections on the associate's work, lab bills the agreement assigns to either side, and any balance remaining in either direction.

Compute each line from your practice-management report and agree the numbers in writing before the last day.

One caution — do not net a disputed adjustment out of the check on your own authority.

California makes it unlawful to collect or receive back any part of wages already paid, and Texas bars withholding or diverting wages unless a court ordered it, the law authorizes it, or the employee authorized it in writing for a lawful purpose.

If the money is genuinely disputed, ask employment counsel about your state's process before touching the check.

Tail coverage only matters if the associate's policy is claims-made.

The Massachusetts Division of Insurance explains the two forms this way: an occurrence policy covers injury that occurs during the policy period regardless of when the claim is actually made, while a claims-made policy generally covers a claim only if it is made during the policy period or an extended reporting period.

That extended reporting period — the tail — lets an insured report a claim after the claims-made policy expires, and its terms should be specified in the policy itself.

Our research found no statute that settles who buys tail when an associate leaves: tail responsibility is a negotiated contract term, which is why the associate agreement should name it while relations are good.

Our guide to malpractice and tail coverage for associates covers the clauses in detail.

Registrations outlive the employment, so the departure is a reporting event.

A Medicare-enrolled practitioner must report a change, addition or deletion of a practice location to their Medicare contractor within 30 days, and other enrollment changes within 90 days — and dentists enrolled in Medicare fall under that reporting rule.

When your associate leaves, their practice location at your address is a deletion to report on that 30-day clock.

Private dental payer credentialing is contract territory.

Each payer agreement sets its own notice provisions for panel and roster changes, and those private terms were not part of this page's research — read the panel-maintenance section of each contract and diary whatever notice it requires.

DEA registration is location-specific: federal rules require a separate registration for each principal place of professional practice where controlled substances are dispensed, and a registrant changes the name or address on a registration by requesting a modification from the DEA Registration Unit, in writing or online.

If the associate holds a registration tied to your address, resolve what happens to it while they are still reachable — the modification is easier to file during the notice period than after the forwarding address exists.

A departure touches contracts, pay, insurance and compliance in the same week.
