    What does "M53: Missing/incomplete/invalid days or units of service" mean?

    Thank you

    Depending on where you are seeing this error message (assuming in your Claims system) and in what context, I have two possible explanations:

    Missing/Invalid/Incomplete Data from Submitted Claim
    1) Refers to situations where additional data is needed from the billing provider (probably you) for missing or invalid data on the submitted claim, e/g/ and 837 or D.0.

    Billed Service No Covered by Health Plan
    2) Refers to situations where the billed service is not covered by the health plan.

    Hope this is helpful, if not please expound on your situation.
