MA44 Remark Code: No Appeal Rights, Decision Based on Law

MA44 is an alert stating there are no appeal rights for this adjudication because the decision is based on law. The payer applied a statutory or regulatory rule, not a discretionary judgment, so the normal appeal process does not apply.

What MA44 means

Most payer decisions involve judgment, such as whether a service was medically necessary, and can be appealed. Some decisions are fixed by law: a statutory exclusion, a rule that applies automatically, or a payment amount set by regulation. MA44 tells you this decision is one of those. Because the outcome follows directly from the law, there is no appeal route.

The paired reason code identifies the rule applied.

What to do

  1. Read the paired CARC to identify the rule.
  2. Check the facts. Confirm that dates, codes, and patient information on the claim were correct, because the rule may have been triggered by an error.
  3. Correct and resubmit if a data error caused the rule to apply, following the payer’s corrected-claim process.
  4. Post the adjustment if the claim was correct. Bill the patient only for PR amounts.
  5. Adjust future billing so services excluded by law are identified before they are provided.
