An audit notice from the state can put your revenue, reputation and license at risk. Many Maryland providers get flagged over routine billing habits they never questioned. Knowing which errors draw attention can help you fix them before the state finds them.
Billing mistakes that draw state scrutiny
Maryland reviewers compare your medical records against every claim you submit. Certain errors stand out when they appear as patterns:
- Upcoding: Billing a higher service code than your notes support
- Unbundling: Splitting one procedure into separate codes to increase payment.
- Insufficient documentation: Missing signatures, incomplete notes or no proof of medical necessity.
- Duplicate billing: Submitting the same claim or service more than once.
- Missing prior authorizations: Billing services that needed approval you never obtained.
State rules under COMAR 10.09.36.03 require clear records that prove medical necessity for every billed service.
How Maryland reviewers flag anomalies
The state uses data tools to compare your billing against similar providers. Contract reviewers such as Qlarant check whether your records match your claims. Unusual billing volume, repeated code pairings and odd service frequency can all prompt a closer look.
Audits can escalate. Findings that suggest intent may lead to civil or criminal fraud referrals.
Steps to take after an audit notice or subpoena
Do not miss the response deadline in the notice. Save all records and pause any routine document destruction. Never change or backdate notes. That mistake can turn a billing dispute into a fraud case. Pick one person to handle all state communications.
Why early action protects your practice
Upcoding, unbundling and thin documentation remain the most common audit triggers in Maryland. Reviewers rely on data comparisons, so patterns matter more than isolated mistakes. Unresolved findings can grow into Medicaid fraud investigations with civil and criminal exposure.
Understanding these risks helps you correct billing practices before an audit becomes an enforcement action. If your audit involves a subpoena or possible fraud allegations, a defense lawyer’s input may help.
