Direct Answer: What CO-213 Means and How to Fix It
Denial code CO-213 indicates non-compliance with physician self-referral prohibition legislation (Stark Law) or payer-specific anti-kickback policies.
Immediate action required: Review the referring physician’s financial relationships with your facility, verify compliance with Stark Law exceptions, and ensure proper documentation exists for any financial arrangements. This denial typically results from services billed when a physician refers patients to entities where they have a financial interest without meeting specific legal exceptions. Resolution involves documenting compliance with safe harbor provisions, correcting referral patterns, or appealing with proper legal documentation when arrangements are legitimate.
Root Causes That Trigger CO-213 Denials
Understanding what triggers a CO-213 denial is crucial for both resolution and prevention. The primary causes stem from violations of federal Stark Law (42 U.S.C. § 1395nn) and similar state regulations designed to prevent conflicts of interest in healthcare referrals.
Financial Relationship Red Flags:
- Physician ownership in diagnostic imaging centers, laboratories, or specialty clinics
- Compensation arrangements that vary with referral volume
- Medical directorships without fair market value documentation
- Space or equipment leases below market rates
- Investment interests in entities receiving referrals
Documentation Deficiencies:
- Missing written agreements for compensation arrangements
- Lack of fair market value assessments for services
- Inadequate records of compliance committee reviews
- Absence of legal counsel opinions on arrangements
Referral Pattern Anomalies: Payers use sophisticated analytics to identify unusual referral patterns. Claims are flagged when statistical analysis reveals referral volumes that significantly exceed peer benchmarks or show sudden increases coinciding with financial arrangements.
Real-World Case Study: Cardiology Group Self-Referral Violation
Patient: Robert Chen, Age 67
Insurance: Medicare Advantage (Humana)
Denial Code: CO-213
Amount: $2,847 for cardiac catheterisation
Scenario: Dr. Martinez, a cardiologist in private practice, referred Mr. Chen for cardiac catheterization at Riverside Cardiac Center. Unknown to the billing department, Dr. Martinez had recently acquired a 15% ownership stake in Riverside through a physician investment group. The facility had not updated their compliance documentation or implemented new referral protocols following the ownership change.
Resolution Steps:
- Compliance officer reviewed Dr. Martinez’s ownership documentation
- Legal counsel assessed whether ownership met Stark Law’s in-office ancillary services exception
- Discovered the arrangement fell outside safe harbor provisions
- Implemented immediate referral restrictions for Dr. Martinez
- Filed corrective action plan with Medicare
- Negotiated settlement for affected claims
Outcome: Three-month resolution timeline, $45,000 in total claim adjustments, implementation of monthly compliance monitoring
Lesson Learned: Ownership changes must trigger immediate compliance reviews and referral protocol updates before any claims are submitted.

Frequently Asked Questions
Q: How quickly must we respond to CO-213 denials? A: Initial response should occur within 24-48 hours to assess compliance exposure. Formal appeals must be submitted within payer-specific timeframes, typically 30-120 days from denial date.
Q: Can we continue billing while appealing CO-213 denials? A: New claims for the same referring provider relationship should be suspended pending compliance review and corrective action implementation.
Q: What’s the difference between Stark Law and Anti-Kickback Statute violations? A: Stark Law is a strict liability statute focusing on referral relationships, while Anti-Kickback Statute requires intent to induce referrals. Both can trigger CO-213 denials.
Q: Are there safe harbor provisions that allow physician financial relationships? A: Yes, numerous exceptions exist including fair market value compensation, physician recruitment, and in-office ancillary services, but each requires specific documentation and compliance requirements.
Q: How do payers detect potential self-referral violations? A: Sophisticated analytics identify unusual referral patterns, cross-reference provider databases, and flag relationships requiring review based on volume and timing anomalies.
