PIP, Medical Liens & Reimbursement in Washington
Medical bills after a Washington crash can involve several different payment systems. Personal injury protection can pay qualifying medical expenses and other benefits without waiting for a fault determination. Medical providers can acquire statutory liens against a tort recovery. And an insurer that paid benefits may later assert reimbursement or subrogation rights. These systems overlap, but they are not the same.
Washington PIP is first-party insurance for crash-related losses
Personal injury protection—PIP—is coverage purchased under an automobile policy for specified losses sustained by an insured because of an automobile accident.
This allows qualifying medical bills and certain other losses to be addressed while the liability claim may still be under investigation or litigation.
PIP
The injured insured seeks contractual benefits under an applicable automobile insurance policy.
Liability claim
The injured person seeks tort damages from the driver or other entity legally responsible for causing the collision.
PIP coverage follows Washington's statutory definition of “insured”
RCW 48.22.005 includes several categories.
An insured can include:
- the named insured;
- a qualifying resident relative;
- a resident ward, foster child or stepchild;
- a person injured while occupying or using the insured automobile with permission; and
- a pedestrian accidentally struck by the insured automobile.
Owned and regularly used unlisted vehicles can create important exceptions
RCW 48.22.090 permits specified PIP exclusions where the named insured or a relative is occupying another vehicle that is owned by or regularly available to that person but is not listed on the declarations page of the policy under which PIP is claimed.
Other statutory exceptions include intentional self-injury, qualifying racing activity and injury arising from the insured's use of an automobile in committing a felony.
Washington's minimum PIP package contains four benefits
Under RCW 48.22.095, insurers must offer at least:
$10,000
Medical and hospital benefits for each insured.
$2,000
Funeral expense benefit.
$10,000
Income continuation, subject to a $200 weekly limit.
$5,000
Loss-of-services benefits, subject to a $200 weekly limit.
Washington requires a higher PIP option on request
RCW 48.22.100 requires an insurer, when requested by the named insured, to offer higher limits:
| Benefit | Minimum option | Higher option |
|---|---|---|
| Medical / hospital | $10,000 | $35,000 |
| Funeral | $2,000 | $2,000 |
| Income continuation | $10,000 / $200 week | $35,000 / $700 week |
| Loss of services | $5,000 / $200 week | $14,600 total |
Medical benefits cover reasonable and necessary accident-related care
RCW 48.22.005 defines medical and hospital benefits as payment of reasonable and necessary expenses for qualifying health care resulting from the automobile accident.
Covered services can include:
- licensed health care services;
- ambulance service;
- hospital care;
- professional nursing;
- pharmaceuticals;
- prosthetic devices; and
- eyeglasses.
Income continuation has a waiting period and statutory coordination rule
Washington's PIP income-continuation benefit begins 14 days after the accident.
The benefit ends at the earliest of:
- the date the insured can reasonably perform the duties of the usual occupation;
- 54 weeks after the accident; or
- the insured's death.
Loss-of-services benefits pay for replacement household services
Washington defines loss-of-services benefits as reimbursement for reasonable expenses paid to people outside the insured's household to perform services the injured person ordinarily would have performed without compensation.
The services must actually be rendered.
PIP is optional—but Washington requires a written rejection
RCW 48.22.085 requires PIP to be offered with new and renewed automobile liability policies.
A named insured may reject PIP in writing. Once properly rejected:
- the rejection binds all levels of PIP coverage;
- it binds everyone who otherwise might have qualified as an insured;
- it carries through supplemental policies;
- it carries through renewals and replacements; and
- coverage need not return until a named insured requests it in writing.
PIP does not automatically make every medical invoice payable
PIP covers actual qualifying loss or expense incurred.
A medical bill must satisfy the Washington requirements that the treatment be:
- reasonable;
- necessary;
- related to the automobile accident; and
- incurred within three years after the accident.
Washington specifically regulates PIP medical denials and treatment cutoffs
WAC 284-30-395 applies when an insurer relies on medical opinion to deny, limit or terminate PIP medical and hospital benefits.
Before denying, limiting or terminating those benefits, the insurer must provide written disclosure explaining the coverage and the permissible grounds.
1. treatment is not reasonable;
2. treatment is not necessary;
3. treatment is not related to the accident; or
4. the expense was not incurred within three years of the accident.
If the insurer decides to deny, limit or terminate benefits, it must give the insured a written explanation containing the true reason in clear and understandable language.
The reviewing medical professional must have appropriate qualifications
WAC 284-30-395 requires a professional used by the insurer to review a PIP medical denial to be currently licensed, certified or registered in the same health field or specialty as the treating professional whose treatment is being reviewed.
Where several providers are involved, the rule ordinarily requires review by a professional in the same field or specialty as the principal prescribing or diagnosing provider unless the insured and insurer agree otherwise.
“Maximum medical improvement” is not an additional Washington PIP cutoff
The Washington Supreme Court held that an insurer could not add “maximum medical improvement” as an additional condition for payment of PIP medical benefits. The four grounds in WAC 284-30-395 are exclusive.
A PIP medical dispute does not permit the insurer to hold unrelated property benefits hostage
WAC 284-30-395 expressly provides that an insurer may not refuse payment of covered property-damage expenses solely because the insured did not attend or chose not to participate in an independent medical examination requested under PIP coverage.
A medical-provider lien is different from the medical bill itself
Chapter 60.44 RCW gives specified providers a statutory lien against the injured person's tort claim or recovery for services provided because of a traumatic injury.
Potential lien claimants include:
- ambulance services;
- hospitals;
- licensed nurses;
- licensed practitioners;
- physicians; and
- surgeons.
Washington imposes specific requirements for a provider to obtain the statutory lien
RCW 60.44.020 requires the provider, among other things, to disclose the use of liens as part of its billing and collection practices and to file a verified notice of claim with the county auditor where the services were performed.
The notice identifies information including:
- the lien claimant;
- the patient;
- the accident circumstances;
- the nature of the injury where applicable; and
- the tortfeasor when known.
Washington caps chapter 60.44 medical liens collectively at 25% of the recovery
RCW 60.44.010 contains a particularly important limitation.
Example:
| Tort settlement | Filed provider liens | Chapter 60.44 aggregate ceiling |
|---|---|---|
| $100,000 | $45,000 | $25,000 maximum statutory lien burden |
A tort settlement does not automatically eliminate a perfected medical lien
RCW 60.44.050 protects a qualifying lien when the patient and tortfeasor or liability insurer settle.
Washington also regulates enforcement and release of the lien
RCW 60.44.060 permits enforcement of the lien by suit brought within one year after filing of the lien.
After payment or settlement and acceptance of the amount due to the lien claimant, the claimant generally must prepare and deliver a release of the paid lien rights within 30 days.
Not every reimbursement claim is a chapter 60.44 lien
A serious injury claim can contain several completely different payment interests:
| Claim | Source |
|---|---|
| PIP reimbursement | Auto policy, subrogation law and Washington made-whole doctrine |
| Hospital / provider lien | Chapter 60.44 RCW |
| Health-plan reimbursement | Plan contract plus applicable state or federal law |
| Workers' compensation | Title 51 RCW |
| Medicaid / public-benefit recovery | Separate statutory reimbursement system |
| Medicare | Separate federal reimbursement system |
PIP payments can create later reimbursement or subrogation issues
Suppose the PIP insurer pays $10,000 of medical bills and the injured person later recovers damages from the negligent driver.
Depending on the policy and circumstances, the PIP insurer may seek to recover amounts it previously paid.
Insurer pursues tortfeasor
The insurer seeks recovery by stepping into rights arising from the insured's loss.
Insured obtained recovery
The policy may permit reimbursement from qualifying proceeds the injured insured recovered from the responsible party.
Related insurance benefits
A carrier may claim a contractual credit to avoid duplicating payment for the same compensable loss.
Washington generally puts the injured insured ahead of the insurer
Washington adopted the made-whole principle: an insurer ordinarily can recover from a tort recovery only from the excess remaining after its insured has been fully compensated for the loss.
Reaffirmed Washington's broad made-whole doctrine and rejected an artificially narrow approach. The doctrine applies when an insurer seeks recovery through mechanisms such as reimbursement, subrogation or qualifying offsets.
“Made whole” means the insured's total damages—not merely the medical bills PIP paid
A crash can cause damages far beyond the medical expenses paid by PIP.
Total compensatory damages can include:
- medical expenses;
- lost income;
- future losses;
- pain and suffering;
- disability;
- other noneconomic damages; and
- other legally compensable loss.
The insured could apply a limited tort recovery toward otherwise uncompensated damages rather than allowing the PIP insurer to treat the settlement as though it necessarily duplicated the medical benefits already paid.
Washington applies the made-whole principle to PIP offsets as well
Washington stated that the made-whole doctrine applies when an insurer seeks an offset, subrogation or reimbursement for PIP benefits already paid.
If the insured creates the recovery fund, the insurer may have to share the cost of creating it
Washington required the PIP insurer under the policy provisions at issue to bear its share of the reasonable expenses incurred by the insured in securing the tort recovery from which the insurer sought reimbursement.
Applied the common-fund principle where the insured's efforts produced liability and UIM proceeds from which the PIP insurer recouped its payments. The insurer had to contribute a pro rata share of the expenses that created the recovery.
Do not confuse reimbursement reduction with reduction of the underlying bill
Several numbers may differ:
- the provider's original charge;
- the amount PIP paid;
- the amount health insurance paid;
- the amount written off by contract;
- the amount asserted as a statutory lien;
- the PIP insurer's claimed reimbursement amount; and
- the amount ultimately payable from settlement.
Before settling, obtain every reimbursement and lien claim in writing
A settlement figure cannot be evaluated intelligently without knowing how much of the recovery may have to be paid to others.
Before final distribution, obtain:
- the PIP payment ledger;
- the PIP reimbursement or subrogation position;
- recorded chapter 60.44 liens;
- provider balances;
- health-plan reimbursement claims;
- workers' compensation recovery information;
- government-benefit reimbursement claims where applicable; and
- written lien releases or payoff agreements.
Do not let a liability insurer resolve your PIP reimbursement rights for you
The injured person's dispute with a PIP insurer is a first-party insurance matter. The tortfeasor's insurer represents a different financial interest.
• whether the reimbursement right exists;
• whether the claimant has been made whole;
• whether fees and costs must be shared;
• whether the amount duplicates damages recovered; and
• whether the policy or applicable law changes the analysis.
Washington requires disclosure when an insurer may seek reimbursement
WAC 284-30-350 provides that an insurer may not make a benefit payment without clearly advising the payee in writing when the insurer may later require reimbursement.
October 18, 2026 PIP rule update
Washington's broader claims-handling amendments become effective October 18, 2026.
The amended version of WAC 284-30-395 continues the substantive PIP protection central to this guide:
- the same four permissible grounds for limiting medical benefits;
- written explanation of the actual reason;
- appropriate medical-review credentials;
- protection of property benefits from PIP-IME disputes; and
- specified arbitration protections.

Bottom line
Washington PIP is optional first-party insurance, but every qualifying auto policy must offer it and rejection must be in writing. Minimum PIP includes $10,000 in medical benefits, with higher $35,000 medical coverage available on request. PIP medical benefits pay reasonable, necessary, accident-related expenses incurred within three years, and Washington tightly regulates medical cutoffs and requires meaningful written explanations. Separately, hospitals and specified medical providers can perfect chapter 60.44 liens against tort recoveries, but those statutory liens are collectively capped at 25% of the recovery. A third system arises when a PIP insurer seeks reimbursement, subrogation or an offset after another source pays damages. Washington's made-whole doctrine generally places the injured insured first, and Mahler and Winters require attention to the legal expenses that created the recovery. Before settling a bodily-injury claim, identify every PIP payment, lien, reimbursement demand and other payment interest, determine its actual legal basis, and calculate the claimant's net recovery before signing the release.
