RARC M49: Missing or Invalid Value Codes or Amounts
The claim is being held or denied because required value codes or their associated dollar amounts are missing, incomplete, or entered incorrectly — correct the value code fields and resubmit.
What Does RARC M49 Mean?
M49 indicates that the payer found a problem with the value codes reported on the claim form. Value codes are the two-digit fields (and their corresponding monetary amounts) on institutional claims (UB-04) that convey specific financial or coverage information — things like the estimated amount due from the patient, Medicare blood deductible amounts, or spend-down liability figures. When these fields are blank, contain an unrecognized code, or have amounts that do not align with what the payer expects, the claim cannot be adjudicated properly.
This remark code often surfaces on facility claims rather than professional claims, since the UB-04 form is where value codes live. Common triggers include leaving the amount field at zero when a dollar figure is required, entering a value code that does not apply to the claim type (for example, using an inpatient-only value code on an outpatient claim), or omitting a value code that the payer's processing rules require for the specific benefit category.
M49 is frequently paired with CARC codes in the 16 (missing information) or 252 (additional information required) family. When you see it alongside a request for additional information, the payer is typically telling you exactly which data element is problematic — check the accompanying remark or adjustment reason for clues about which value code is at issue.
What to Do
Pull the claim and review all value code fields on the UB-04 (form locators 39–41). Cross-reference each value code against the payer's requirements for the specific claim type and benefit category. If a required value code is missing, add it with the correct corresponding amount. If the amount seems incorrect, verify it against the patient's account and coverage details. Once corrections are made, resubmit the claim.
If the remittance does not specify which value code triggered the issue, contact the payer's provider services line with the claim number to get clarification before resubmitting. Billing systems that auto-populate value codes from charge entry can sometimes carry stale defaults — periodically auditing these templates, especially after payer policy updates, can prevent M49 from recurring across multiple claims.
Common Scenarios
- A hospital outpatient claim is returned because value code 80 (covering days) was left blank when the payer requires it to calculate the benefit period for the patient's coverage.
- A skilled nursing facility claim is denied because the Medicare spend-down amount in value code 23 does not match what the state Medicaid agency reported, causing a coordination of benefits mismatch.
- A billing system upgrade resets default value code mappings, and several weeks of institutional claims go out with value code 17 (outlier day count) populated on claims that do not qualify for outlier payments.
