If your lab does drug testing, you will get audited. Do you have a plan for this?
We all know that drug testing is an essential part of good clinical practice.
Medical providers need confirmatory/definitive drug testing results to track medication adherence (i.e. opioid therapy), prevent dangerous drug-drug interactions, and identify the presence of a substance use disorder (SUD) or relapse into active addiction.
However, the OIG recently reported that due to Fraud and Abuse from a period between Jan 2016 - Dec 2020, “Medicare paid $704.2 million for definitive drug testing services that were at risk for noncompliance with Medicare requirements”.
Moreover, Medicare (W-00-22-35876, 2024) and the OIG (A-09-21-03006, 2023) have announced their plans to audit more drug testing labs for documentation and compliance, while commercial payers are escalating their prior auth and claim denials for “lack of medical necessity,” which is really a lack of DOCUMENTATION of medical necessity.
IF IT’S NOT DOCUMENTED, IT DIDN’T HAPPEN.
The reality is that no matter how many times you ask, busy providers aren’t going to document medical necessity well enough for your lab’s compliance or reimbursement needs.
“Cellarian solves your problem by creating compliant, patient-specific medical necessity documentation, which protects you and your provider without extra work.”

Lack of Medical Necessity Documentation is the Most Preventable Cause of Revenue Loss
Labs write off millions of dollars annually.
Drug testing is now a high-volume, low-dollar service. Providers are too overwhelmed to adequately document a patient’s medical necessity reasons for every test ordered. Yet, without this documentation, the revenue is unreachable.

Our Service: Automated Clinical Documentation to maximize revenue
Don’t throw more people at the problem. Automate.
Cellarian provides intelligent process automation to clinical documentation, prior authorizations, and denials management to help our clients maximize available revenue capture and decrease the administrative burden for diagnostic labs and their physician customers.
The Challenges
A solution is needed to intelligently automate clinical documentation processes, stay up to date on changes in payer medical necessity and reimbursement guidelines, and accelerate the time from claim denial to successful payment.
Insurance payers overload doctors with excessive medical necessity documentation requirements as a strategy to deny payment for services.
Laboratory Benefit Management process automation by payers uses denials to drive lab behavior towards low-reimbursement codes, since Labs need doctors to provide proper clinical documentation to get paid.
Doctors don’t perceive benefit from the cost of adding clinical documentation, so they rarely do it, resulting in denied payments and significant revenue loss that labs cannot recover without documentation.
Denied claims are expensive to appeal, so labs are forced to either write off on average 20% of monthly accounts receivable or spend more money/staff resources trying to fight the denials which are often never paid due to lack of documentation. These additional expenses further decrease monthly net profits.
