Southern California Healthcare Fraud Defense Lawyer Explains Charges

Practice Area:Criminal Law
Jurisdiction:California


A Southern California healthcare fraud defense lawyer can assess whether disputed medical claims involve billing errors or alleged intentional fraud.


Investigators may compare billing codes, patient records, medical necessity, and services actually provided. Civil repayment demands, administrative sanctions, and criminal charges follow different standards and procedures. Preserve original records and identify the agency, allegations, and response deadline before addressing a request.



1. When Does a Billing Discrepancy Raise Fraud Concerns?


A missing progress note can lead to a denied claim, but denial alone does not prove fraud. The central questions are what care occurred, what was billed, and what the person submitting the claim knew.


Reconstruct the Service Behind Each Claim

A higher-paying code may reflect the treatment documented, a coding mistake, or an unsupported charge. Contemporaneous records help distinguish them.

  • Match service dates, clinicians, codes, and units to patient encounters.
  • Compare orders, progress notes, test results, and medical necessity requirements.
  • Trace corrections and submission histories without changing source records.

Disputes about codes and reimbursement also arise in Medicare billing fraud matters.

Separate Mistakes from Statutory Knowledge Requirements

The criminal statute requires a knowing and willful fraudulent scheme, but not awareness of the statute itself. Civil liability uses a separate knowledge test.

2. Is the Matter an Audit, Civil Claim, or Criminal Investigation?

One set of claims may lead to a repayment demand, a payment suspension, and a criminal inquiry. These proceedings can overlap, but a decision in one does not necessarily decide the others.


Identify the Legal Track before Responding

An audit finding may establish an overpayment dispute without resolving anyone’s criminal intent.

  • Payment audits may seek corrections, recoupment, or an administrative appeal.
  • Civil False Claims Act actions address qualifying false claims, damages, and penalties.
  • Criminal proceedings require proof of the charged offense under criminal standards.

For the distinct civil framework, see False Claims Act.

Distinguish Medicare from Medi-Cal Enforcement

A Medicare claim audit and a Medi-Cal fraud referral follow different rules. Welfare and Institutions Code § 14107 addresses specified fraudulent acts involving the state program.

  • Identify the payer, claim period, agency, and payment rules at issue.
  • For a DHCS suspension under § 14107.11, check whether the allegation is credible and whether a good-cause exception applies.
  • Determine whether an administrative action, law enforcement referral, or both exist.

Suspension can affect cash flow before any criminal verdict. Related rules appear in Medicaid fraud defense.


3. What Records Matter When Investigators Request Information?


Investigators may seek the same claim in a medical chart, billing system, and vendor export. A subpoena can compel production; an informal request may not. Preserve the original sources before deciding how to respond.


Preserve Records Across Clinical and Billing Systems

An outside billing company may hold submission logs absent from the clinic’s system.

  • Keep claims, remittances, patient notes, audit trails, and corrected submissions.
  • Retain staff communications, training records, internal audits, and refund history.
  • Identify who documented, coded, approved, transmitted, or revised each claim.

Fact-finding and preservation issues may also involve government and internal investigations.

Assess Production Scope and Confidentiality

Production can involve patient privacy and privilege questions even when the underlying billing records must be disclosed.

  • Confirm the issuer, compulsory authority, document categories, and response date.
  • Assess privacy obligations, appropriate objections, and permitted disclosure methods.
  • Review privilege and possible waiver before providing internal legal assessments.

Routine charts and claims do not become privileged merely because a lawyer reviews them.


4. Which Deadlines and Forums Govern the Response?


A missed payment-appeal deadline may foreclose administrative review, while a criminal subpoena may impose a different production date. Read each notice independently.


Read the Notice for Its Actual Appeal Route

For an appealable Medicare fee-for-service initial claim determination, the first-level redetermination deadline is generally 120 days after receipt. That period does not govern every recoupment or fraud notice.

  • Identify whether the document is an initial determination, demand, suspension, or subpoena.
  • Check the appeal method, receipt rules, and required supporting material.
  • Track separate deadlines for parallel administrative and court proceedings.

A payment appeal does not necessarily answer a criminal investigative demand.

Verify the Agency and Court Named in the Case

The location of the provider does not alone establish the proper court. The charging document and governing venue rules control.

  • Check whether CMS, DHCS, HHS-OIG, DOJ, or another authority issued the notice.
  • Confirm the named court or agency and its filing instructions.
  • Preserve service records and proof of any timely response.

Administrative findings are not criminal verdicts.


5. Frequently Asked Questions


Can a billing employee face charges when a physician signed the claim?

A billing employee’s knowledge and involvement may matter independently of a physician’s signature. The specific charge determines the required proof.


Can a licensing board act before a criminal conviction?

Yes. A licensing board may begin separate proceedings before a criminal case ends, but discipline requires a basis under the board’s governing law.


Does hiring an outside billing company eliminate provider responsibility?

No. The provider’s obligations may continue under program rules, while contracts and approval records help clarify who handled disputed claims.


Must a provider repay every amount an auditor disputes?

Not necessarily. The audit finding, applicable appeal process, and any identified overpayment must be assessed separately from a criminal allegation.



6. Discuss Healthcare Fraud Allegations with SJKP


An unexpected audit letter or subpoena can leave a practice uncertain about its next decision. SJKP’s attorneys can review the claims, clinical records, and legal process identified in the notice. Contact SJKP to arrange a confidential consultation about the allegations.
