Hello- I would like some assistance with this case study from the book "Case Studies in Health Information Management"

Case Study 4-17

Chargemaster Audit

You are part of the chargemaster maintenance team, but the day-to day operations tend to fall to you in your role as chargemaster coordinator. You spend a lot of your time each day auditing the chargemaster. You have printed out a portion of the chargemaster to review. These entries from the Chargemaster Report to Audit shown in Table 4-15 are to be audited; the audit will look for comprehensiveness of information and data quality.

What problems can you identify?
