Standing Orders and Custom Lab Profiles: When a Requisition Manufactures Demand

Laboratory standing order requirements begin with a treating clinician’s decision for an individual patient and medical records that support the testing. Under Medicare’s ordering rules, the clinician requests the tests and uses their results in care. The trouble starts when a laboratory turns a provider’s preferred test menu into an order for every patient. The requisition carries the clinician’s name. The tests can still reflect what the laboratory wanted to sell.

For someone in laboratory sales, billing or clinical operations, the important distinction is visible before a claim goes out. A recurring order follows a patient’s treatment. A blanket profile applies the same selection across a practice. When the laboratory performs and bills that selection repeatedly, the original form can account for a great deal of unnecessary testing.

What Does a Standing Lab Order Cover?

A standing lab order can request specified tests for one patient on a recurring schedule during an extended course of treatment. The patient’s clinical record supplies the reason for repeating them. That is different from assigning a standard set of tests to everyone with a similar condition.

The Medicare ordering and documentation rule puts the medical-necessity documentation in the ordering clinician’s record. The laboratory must retain what it receives and document that its claim accurately reflects that information. The clinical decision and the bill live in different places.

The HHS Office of Inspector General’s August 1998 laboratory compliance guidance called for periodic monitoring, a fixed term of validity and renewal when a standing order expires.

Those controls make the duration of an order part of the inquiry. We examine the tests selected, the planned frequency, the treatment supporting that schedule and the renewal that authorized continued testing. A change in the patient’s care raises a concrete question about the next requisition: where did the clinician authorize the tests now being billed?

Annual notices about custom profiles serve a separate purpose. The same guidance called for laboratories to explain the Medicare reimbursement for each component and the implications of ordering the profile. It recommended a physician acknowledgment. That acknowledgment concerns the provider’s understanding of the profile. The patient’s chart still has to support the testing.

Reflex Laboratory Testing Medical Necessity

An additional test needs a clinical reason and authority to perform it. A recurring order repeats testing on a schedule. A conditional order authorizes an additional test when an initial result meets a condition set by the treating clinician.

The Medicare Benefit Policy Manual gives a simple example: the clinician orders an initial test and directs the laboratory to perform another if the first is negative. The condition belongs in the order. The result then determines whether the laboratory performs the additional test.

Laboratories also use reflex testing to describe automatic additional testing under their standard operating procedures when results are abnormal or meet other criteria. That laboratory definition describes how the work runs. The payment question still reaches back to the clinician’s order and the patient’s need.

For pathology specimens received with a requisition but no specific test order, Medicare’s manual ties additional stains to a complete and accurate diagnosis. The stains must be medically necessary, communicated to the treating physician and documented. A laboratory’s routine cannot supply the patient’s need.

Inform Diagnostics illustrates the alleged failure at that point. Its July 2022 settlement of $16 million addressed allegations that its policy of routine additional testing caused it to perform many medically unnecessary tests. What matters is what the doctor asked for, what justified another test and what the lab billed on top of it.

When Are Toxicology Tests Unnecessary?

Toxicology tests become unnecessary when a blanket profile produces testing beyond an individual patient’s clinical needs.

An order that preserves the clinician’s reasoning gives the laboratory a defined question to answer. A preset sequence that keeps generating tests can lose that connection. The difference is in the patient’s clinical plan, the condition attached to the order and what happened when the result arrived.

What Are Red Flags in Laboratory Ordering?

A prechecked laboratory test panel the physician did not select, a custom profile applied across a practice, and diagnosis codes supplied without the clinician’s diagnostic information are red flags in laboratory ordering. Each shifts a decision about the patient’s care toward the business billing for the tests.

When a lab custom profile applies to every patient in a practice, the word custom deserves attention. Customized for a physician’s account can mean something very different from selected for the patient whose specimen arrived that morning.

The whistleblower complaint against Health Diagnostic Laboratory alleged that its panels included duplicative tests and denied physicians a choice between them:

The allegation concerns the design of the order itself. A physician choosing the panel would also be choosing the tests the laboratory had made inseparable.

A separate whistleblower complaint concerning Berkeley HeartLab described another way to expand an order. It alleged that physicians discussed a Plavix test for individual patients, but Berkeley added it to the follow-up panel on forms sent to the practice’s billing staff. According to the complaint, the physicians did not complete those forms and would learn of the added test from the results.

That is why the version of a form matters. The menu discussed with the physician, the requisition used by office staff and the test set the laboratory performs can tell different stories. The person who knows when a panel changed may know how an extra test became routine.

Whose Records Show What the Clinician Intended?

The treating clinician’s chart shows the clinical decision. The laboratory’s records show what it received, performed and billed. Reading them together exposes the gap a completed requisition can hide.

For an unsigned clinical diagnostic test order, Medicare’s manual requires the physician’s intent to be clearly documented in the medical record. The charted intent matters more than the appearance of the laboratory’s form.

The 2014 review Ethical Perspectives on Urine Drug Screening for Pain Physicians, published in the journal Pain Physician, explains that a negative screen can reflect dosing history and that detection varies with the testing method. The stakes reach beyond the bill:

The diagnosis field deserves the same attention. Medicare permits a laboratory to use a code supplied by the ordering clinician or select the appropriate code from that clinician’s diagnostic narrative. The laboratory must obtain supporting diagnostic information from the clinician. The Inspector General’s guidance specifically addressed computer programs that automatically insert codes without receiving that information.

A code that gets a claim through the billing system cannot supply the patient’s clinical reason for the test. We compare the diagnostic information the practice sent with the information the laboratory used, alongside the order and results.

Model Plan Helps Laboratories Fight Fraud, published in Laboratory Medicine in June 1997, described recommendations for uniform requisitions, annual explanations of profile components and billing, physician acknowledgments and monitoring of standing orders.

The recurring question is who understood and chose the tests. An annual acknowledgment, a profile name and a diagnosis field each answer only part of it.

Laboratory Standing Order Settlements Comparison

The same ordering problem recurs at different businesses: a test menu selected for a provider becomes testing billed for individual patients. The useful comparison is what each company allegedly did, what it admitted where there was an admission, and which part of the ordering process changed.

Millennium Health and the Provider’s Custom Profile

In October 2015, Millennium Health resolved allegations of unnecessary urine drug testing through a $227 million civil component of its broader resolution. The government alleged that Millennium promoted custom profiles that operated as standing orders, causing physicians to order large numbers of tests without assessing each patient’s needs.

The allegations also involved free testing supplies for physicians who agreed to refer testing. The form and the referral incentive belonged to the same commercial relationship: the laboratory sought the specimens and promoted the tests it would run on them.

Genotox Admitted Applying Profiles Across Patients

Genotox Laboratories admitted the custom-profile conduct in its April 2023 civil settlement. It offered forms on which providers preselected tests, then performed and billed those tests for all or nearly all of the providers’ patients, generally in the highest reimbursement categories.

The admission included definitive drug testing for 22 or more drug classes. That detail makes the consequence of the form visible. A provider’s selection could reach across the practice and into a broad, expensive test category each time a specimen arrived. Public health care programs bear the cost when a provider’s default becomes unnecessary testing billed for each patient.

Precision and the Review of the Original Order

Precision Toxicology, doing business as Precision Diagnostics, agreed to a $27 million settlement in October 2024. The government alleged that it promoted custom profiles that functioned as standing orders and produced excessive urine drug testing without individualized assessments.

Its corporate integrity agreement reaches back into that process. The reviewer must examine requisitions and results as well as paid claims. That requirement puts the document that generated the testing beside the claim that generated the payment.

What Did the Physicians Toxicology Settlement Address?

The Physicians Toxicology Laboratory settlement addressed allegations of unnecessary drug testing. The January 2025 resolution was $4,425,000 and included a three-year integrity agreement.

How Can Order Reviews Detect and Deter Laboratory Fraud?

Detecting laboratory ordering fraud means connecting the original order and clinical rationale to the specimen, result, claim and payment. Deterrence reaches the people designing the forms and selling the testing as well as the people submitting the bill.

Precision’s executed corporate integrity agreement makes that connection concrete. Its testing report must identify the test, patient, ordering provider, order date and reason for testing. The laboratory must modify its requisitions to capture that information.

The medical director and compliance officer must review the report monthly. Quarterly review reaches providers whose testing frequency or patterns appear excessive and providers who have not regularly reviewed results and acted on them in patient care. Repetition and clinical use are examined together.

Under that agreement, a paid claim without supporting documentation counts as an error and an overpayment. It cannot be replaced with a better-documented claim. The file that cannot support the testing stays in the review.

For an insider, the useful account is just as specific. We connect the practice’s order to the laboratory’s version, the tests performed and the claims paid. If a profile changed, the question is who changed it and where the clinician’s decision appears. If testing repeated, the question is what treatment and renewal supported it. For a reflex test, the question is which result satisfied the condition in the order.

Those connections let us examine how a sales decision, form design or billing instruction reached government payments. A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers.
