Confusing MAC with tuberculosis.

Impact

Reimbursement: Incorrect coding can lead to improper DRG assignment., Compliance: May result in compliance issues with coding standards., Data Quality: Affects accuracy of clinical data and patient records.

Mitigation

Ensure MAC is confirmed by culture or PCR and differentiate from TB using specific tests.

Incorrect MAC vs. TB coding

Impact

Risk of coding MAC as TB due to similar clinical presentations.

Mitigation

Ensure differentiation through specific lab tests and documentation.
