Dissolving a Medical or Dental Practice in Washington State: Patient Records & Asset Liquidation

Current as of: October 4, 2026 Business Dissolution & Liquidation Washington State
Closing a medical or dental clinic in Washington requires strict regulatory compliance. Providers must legally maintain patient records, secure malpractice tail coverage, and formally notify the Washington Department of Health to avoid charges of patient abandonment.

Shutting down a healthcare practice is vastly different from closing a standard retail business. Doctors, dentists, and clinic owners in Washington face a minefield of federal HIPAA laws and state healthcare regulations. If you abruptly lock the doors to your clinic in Seattle, Spokane, or Vancouver without proper planning, you could face severe disciplinary action from state medical boards for 'patient abandonment.' Safely winding down a practice requires months of preparation, from liquidating heavy medical equipment to securely archiving thousands of confidential files. We strongly recommend using our directory to locate an attorney who specializes in Washington healthcare law to guide you through this high-stakes process.

Legal Requirements for Storing Patient Records in WA

One of the most critical aspects of dissolving a practice is handling Protected Health Information (PHI). Record retention mandates vary by license type. Under Wash. Admin. Code § 246-817-310, licensed dentists must retain patient records for at least 6 years from the date of the last treatment. For private medical doctors, while state statutes lack a single general timeline, the Washington Medical Commission Retention of Medical Records Guideline advises maintaining adult records for at least 10 years from the last contact and pediatric records for 21 years from the patient's date of birth. For hospitals, Wash. Rev. Code § 70.41.190 requires records to be preserved for a minimum of 26 years. Furthermore, Wash. Rev. Code § 70.02.080 dictates that you must provide patients with clear access to their health information upon request. When closing, you must designate a secure records custodian-often a specialized medical archiving company-and send a formal written notice to all active patients detailing exactly how they or their new physicians can request their charts in the future.

Liquidating Specialized Medical & Dental Equipment

Medical and dental clinics are full of expensive, highly regulated equipment, such as X-ray machines, MRI scanners, and dental chairs. Selling these assets is not as simple as listing them online. Buyers must often be licensed professionals or certified medical resellers. More importantly, before any computer, diagnostic machine, or server leaves your facility, you must ensure it undergoes a certified data wipe. Under the federal HIPAA Security Rule, codified at 45 C.F.R. § 164.310, failing to destroy PHI on a discarded medical device can lead to massive federal fines. Hiring a certified medical liquidator who provides a Certificate of Data Destruction is absolutely essential.

Handling Malpractice Tail Coverage During Dissolution

Most healthcare providers in Washington carry 'claims-made' medical malpractice insurance. This type of policy only covers lawsuits if the policy is active both when the alleged incident occurred and when the lawsuit is filed. Because patients might discover a misdiagnosis years after you close your clinic, you must purchase 'tail coverage' (an extended reporting endorsement). Tail coverage ensures you remain protected against malpractice claims that are filed long after your clinic is dissolved. Depending on your specialty (e.g., neurosurgery vs. general dentistry), purchasing a tail policy can cost anywhere from 100% to 300% of your final year's standard premium. Budgeting for this expense is a mandatory part of your financial wind-down strategy.

Notifying the WA Department of Health

State agencies must be formally notified of your closure to deactivate your licenses and facility registrations. You must coordinate with the Washington State Department of Health, Olympia and your specific licensing board, such as the Washington Medical Commission, Tumwater or the Dental Quality Assurance Commission, Tumwater, by submitting formal written notification of practice closure and updating your practitioner credential status. Additionally, if your practice possesses controlled substances, you must legally transfer or destroy the medications under the strict supervision of the DEA and the Washington State Pharmacy Quality Assurance Commission, Tumwater, submitting all required final inventory logs.

Frequently Asked Questions (FAQ)

Can I just give patients their original medical records?

No. You must maintain the original records (or secure digital copies) for the applicable retention period (6 years for dental records or at least 10 years for medical charts) to defend yourself in case of a future malpractice claim. You should only provide patients or their new doctors with authorized copies.

What is considered 'patient abandonment' in Washington?

Patient abandonment occurs when a physician terminates the doctor-patient relationship without giving the patient reasonable notice and an opportunity to find a qualified replacement provider, potentially putting the patient's health at risk.

Who pays for copying records when a clinic closes?

Under Washington law, a provider may charge a reasonable, state-regulated fee for copying records. However, as a courtesy during a closure, many clinics absorb the cost to ensure a smooth transition of care.

Do I need to notify Medicare or Medicaid?

Yes. If your practice bills federal or state healthcare programs, you must formally withdraw your enrollment from Medicare and Washington Apple Health (Medicaid) to avoid any future billing fraud liabilities.

How should we handle unearned patient prepayments?

Any funds paid by patients for services that were not ultimately rendered (such as prepaid orthodontic work or elective surgery deposits) must be promptly refunded to the patient or their insurance company before the business accounts are closed.
