MRF correctly encodes billing codes and code types
Most common reasons it failed
| Reason | Hospitals |
|---|---|
| "code|N|type" value "N" is not one of the allowed valid values. | 1 |
| A value is required for "code|N|type". You must encode the missing information. | 1 |
| must have required property 'code_information' | 1 |
| The code and code type pairing do not need to be in the first code and code type columns (i.e., code|N and code|N|type). | 1 |
Why it couldn't be determined (never counted against the hospital)
| Reason | Hospitals |
|---|---|
| The file exceeded a size or time limit CareCarta sets. | 17 |
| CareCarta could not download the source on this attempt. A refusal, a web page in place of the file, or a server error counts against the hospital only if it happens again on a later day. | 16 |
| The CMS validator reported problems CareCarta could not attribute to a specific check, so this one is not called clear. | 12 |
| A checking tool stopped unexpectedly. | 6 |
