CO-237: Legislated or Regulatory Penalty
A regulatory penalty was applied to your payment. Read the RARC for details, verify compliance, and appeal or apply for a hardship exemption if applicable.
What Does CO-237 Mean?
CO-237 applies the regulatory penalty as a contractual reduction that the provider must absorb. This is the standard group code for legislated penalties because the provider is responsible for meeting regulatory requirements, and the financial consequence of non-compliance cannot be shifted to patients.
CARC 237 is not a standard billing denial — it is a penalty reduction applied to the claim based on a specific legislative or regulatory requirement. The penalty could stem from failure to participate in quality reporting programs (MIPS/MACRA), non-compliance with meaningful use requirements, failure to meet electronic prescribing mandates, or other federally or state-mandated programs that carry financial penalties for non-participation.
This code is intentionally broad. The specifics of the penalty are communicated through the accompanying RARC (Remittance Advice Remark Code), which is required for CARC 237. Without reading the RARC, you cannot determine what regulatory requirement triggered the reduction. The penalty is typically calculated as a percentage reduction applied to all applicable claims, not a denial of individual services.
CARC 237 almost always appears with CO (contractual obligation) because the penalty is the provider's financial responsibility. The provider cannot pass regulatory penalties to patients. In some cases, hardship exemptions or exception processes exist through CMS or the relevant regulatory body that can retroactively remove or reduce the penalty.
Common Causes
| Cause | Frequency |
|---|---|
| Non-compliance with healthcare regulatory requirements The provider failed to meet specific legislated or regulatory requirements such as quality reporting mandates, meaningful use requirements, or other CMS program participation rules, resulting in a payment penalty | Most Common |
| Quality reporting penalty The provider did not submit required quality measures data or did not meet quality performance thresholds mandated by legislation such as MACRA/MIPS, resulting in a payment reduction applied as a penalty | Common |
| Documentation or coding non-compliance The claim does not meet legislated documentation standards or coding requirements, and the payer applies a penalty rather than a simple denial for the regulatory violation | Common |
| Failure to meet program participation requirements The provider has not met specific program participation criteria (such as electronic prescribing or health information exchange requirements) that carry legislated payment penalties for non-participation | Occasional |
How to Resolve
Read the RARC to identify the specific regulatory penalty, verify your compliance status, and appeal if the penalty was applied in error or apply for a hardship exemption if eligible.
- Identify the penalty program Read the RARC code to determine which specific regulatory program imposed the penalty (MIPS, meaningful use, e-prescribing, etc.).
- Verify compliance or file for exemption Check your compliance records. If you submitted the required data, appeal with proof. If you missed the requirement, check whether a hardship exemption applies.
- Implement going forward If the penalty is valid, participate fully in the required program going forward to prevent penalties on future claims.
Common RARC Pairings
The RARC code tells you exactly what triggered the CO-237:
| RARC | Description |
|---|---|
| N830 | Payment adjusted based on legislated/regulatory penalty. |
| N831 | Payment adjusted based on quality reporting requirements. |
How to Prevent CO-237
- Stay current with all legislated and regulatory programs affecting your practice (MIPS, MACRA, meaningful use, quality reporting)
- Submit required quality data well before program deadlines
- Apply for hardship exemptions before penalty periods begin if your practice qualifies
- Monitor CMS communications for new or changed penalty programs
- Conduct regular compliance audits to verify all regulatory requirements are being met
General Prevention
- Stay current with all legislated and regulatory requirements that affect your practice, including CMS quality programs, MACRA/MIPS, and state-specific mandates
- Participate fully in required quality reporting programs and submit data within required timeframes
- Conduct regular internal audits to verify compliance with all regulatory requirements before penalties are assessed
- Train staff on the specific legislated requirements and documentation standards that carry financial penalties
- Monitor CMS and state regulatory agency communications for new or changed penalty programs
