M26 Remark Code - Service Level Documentation Issues

The M26 remark code indicates that the documentation provided does not support the billed level of service. It also emphasizes the obligation to refund any amounts collected from the patient that exceed the allowable charge for a less extensive service within a specified timeframe.

How It Relates to the Denial

The M26 remark typically accompanies a claim adjustment reason code that reflects a denial or reduction based on the level of service billed. This combination indicates that the payer found the service level unjustified based on the submitted documentation.

Common Scenarios

1A provider bills for a level 4 office visit but receives an adjustment indicating that only a level 2 visit is justified based on the documentation submitted.
→ The M26 remark points out that the documentation does not substantiate the need for the higher level of service billed, and the provider must consider issuing a refund for any excess payment collected from the patient.
2A physician submits a claim for a complex surgical procedure but the payer adjusts it down to a simpler procedure, citing insufficient documentation.
→ The M26 remark indicates that the level of service billed is not supported by the information provided, and the physician must refund any amounts collected from the patient that exceed the allowable for the simpler service.
3A provider received a denial for a consultation code, with the accompanying reason code stating that the service was not medically necessary.
→ The presence of the M26 remark suggests that the documentation did not justify the level of service billed, and the provider needs to assess any patient payments for potential refunds.

What to Do

  1. Review the documentation submitted for the service to determine if it supports the level billed.
  2. If applicable, prepare to issue a refund to the patient for any amounts collected that exceed the allowable charge for the less extensive service.

What to Check

  • The patient's billing record to confirm the amount collected for the service in question.
  • The claim documentation to assess the level of service billed and the justification provided.
  • The payer's policy on service levels and documentation requirements to ensure compliance.
