How does your office handle it when they receive incomplete charts from providers?

Some examples:

The start and/or stop time is not on the chart.

There is no diagnosis on the chart.

There are no anesthesia providers listed on the chart.

If the above information is not on the actual chart, but it’s on the superbill, do you code it or send it back to the provider to complete the record?

Any input would be appreciated. TIA
