Maryland PIP Medical Bills: Coverage and Payment Deadline Guide

The 30-day rule does not make every medical bill automatically payable. A provider must first identify a covered person and policy, confirm that PIP was not waived or rejected, establish accident relationship and reasonable necessity, present satisfactory proof, and account for the available benefit balance and policy terms.

This guide summarizes Maryland Insurance Article §§ 19-505, 19-506, and 19-508 and Maryland Insurance Administration guidance available on September 30, 2026. It is an operational framework, not a determination of coverage, assignment rights, medical necessity, priority, or the amount due on any claim.

Maryland PIP workflow at a glance

1. Confirm PIP exists before relying on it

Section 19-505 requires Maryland motor-vehicle liability policies to provide the specified medical, hospital, and disability benefits unless they were waived under § 19-506 or rejected under § 19-506.1. Maryland Insurance Administration guidance describes the required offer as at least $2,500. The actual policy may contain higher limits, but the ledger must account for the purchased limit and payments already made.

Section 19-506 permits the first named insured to make an affirmative written waiver. A valid waiver can bind named insureds, listed drivers, and resident family members age 16 or older, subject to statutory exceptions. The waiver is ineffective unless the insurer first provides notice of the nature, extent, and cost of the coverage, and it must use the Commissioner's required form.

2. Identify the covered person and vehicle relationship

Section 19-505 describes several covered groups, including the first named insured and resident family members injured in a motor-vehicle accident, permissive users of the insured vehicle, guests or passengers occupying it, and certain pedestrians or persons using animal- or muscular-powered vehicles when the insured vehicle is involved. The patient's role in the accident and relationship to each available policy should be recorded at intake.

• Patient's legal name, date of birth, address, and household members.
• Accident date, location, report number, and mechanism of injury.
• Whether the patient was a driver, passenger, pedestrian, bicyclist, or other participant.
• Identity of every involved vehicle, owner, operator, and insurer.
• Named-insured, resident-relative, listed-driver, permission, and occupancy facts.
• Policy numbers, claim numbers, adjuster details, PIP limit, paid-to-date amount, and remaining balance.
• Any written waiver, rejection, exclusion, reservation, or coverage denial.

3. Match the expense to § 19-505

The medical component of § 19-505 covers reasonable and necessary expenses arising from the motor-vehicle accident for medical, hospital, and specified related services when incurred within three years after the accident. The three-year incurred-expense window is not a license to delay notice or claim presentation; the policy's original-claim requirement and proof obligations still apply.

A provider packet should make the causal and clinical record understandable without assuming that the bill form proves both. Initial records should describe the accident, symptoms, findings, diagnoses, and treatment plan. Later services should show clinical progression, response, continued need, and any referrals or orders.

4. Calendar the original-claim deadline from the policy

Section 19-508 permits a policy to state a period for presenting the original PIP claim, but that period may not be shorter than 12 months after the accident. The statute creates a floor, not a universal 12-month deadline. The actual policy language may allow more time and should control the operational calendar, subject to current law.

1. Give notice and obtain the PIP application or claim instructions promptly.
2. Confirm the policy's original-claim presentation period in writing.
3. Submit the claimant and accident information needed to open or perfect the claim.
4. Do not wait for treatment to end before preserving the original claim.
5. Keep the policy provision, submission, acknowledgment, and proof of receipt together.

5. Submit satisfactory proof, not merely an aging statement

Section 19-508 starts the payment period when the insurer receives satisfactory proof of claim. The statute does not prescribe one universal provider packet. In practice, the submission should allow the insurer to evaluate the covered person, accident, policy, service, causal relationship, necessity, amount, and person entitled to payment.

• Completed PIP application or other claimant proof requested under the policy.
• Professional or facility bill with complete codes, modifiers, units, dates, and charges.
• Clinical records, orders, referrals, diagnostic results, and itemization appropriate to the service.
• Accident report or other evidence linking the injury and service to the occurrence.
• Coverage verification and current benefit-balance information.
• Assignment, direction-to-pay, authorization, or representative documents when relied upon, without treating them as substitutes for coverage.
• A cover index and provable transmission receipt.

If the carrier requests more information, record what was requested, the request date, whether it is relevant to the claim, the response date, and the supplemental packet. This creates a defensible chronology for deciding when satisfactory proof was available rather than equating the first bill date with the statutory payment date.

6. Apply the 30-day payment and interest rules carefully

Section 19-508 requires the insurer to pay PIP benefits periodically and within 30 days after receiving satisfactory proof. Benefits not paid in accordance with the section and therefore overdue bear simple interest at 1.5% per month. The interest analysis should use the amount proven due, the date satisfactory proof was received, the statutory payment period, and actual payment dates.

7. Separate the common dispute categories

An unpaid Maryland PIP bill may reflect no PIP coverage, an exhausted limit, a person outside the covered class, late original-claim presentation, incomplete proof, lack of accident relationship, a reasonableness or necessity challenge, a coding issue, or a dispute over who may receive payment. Each category needs different evidence. A generic demand that cites only the 30-day provision may miss the actual issue.

Provider teams should also distinguish the patient's insurance claim from the provider's own legal rights. An assignment, direction to pay, representation authorization, and HIPAA authorization perform different functions. Whether a provider may enforce benefits directly depends on the governing documents and current law and should receive claim-specific legal review.
