What it means on your remittance
The claim line itself is shaped wrong for EVV matching — most often because a single line spans 31 days or more, which Pennsylvania's matcher won't process.
Why it happens
- A single claim line spans 31 days or more, which Pennsylvania's EVV matcher won't process.
- The line's format is otherwise malformed for EVV matching purposes.
How to fix it, step by step
- 1Split the claim line so no single line spans more than 30 days.
- 2Resubmit the split lines. Each will be matched to its own visits normally.
How to tell it apart
933 is a claim-shape problem, not a visit problem — your visits can all be perfectly verified and the line still won't match while it spans a month or more.

What does denial ESC 933 mean?
The claim line itself is shaped wrong for EVV matching — most often because a single line spans 31 days or more, which Pennsylvania's matcher won't process.
How do I fix a ESC 933 denial?
Split the claim line so no single line spans more than 30 days, then resubmit.
Why does line span matter to EVV?
The matcher pairs claim lines to specific visits with specific dates. A line covering an open-ended span can't be paired deterministically, so Pennsylvania rejects the format outright.
