2017 ICD-10 DRG AUDIT TARGET AREAS

 COPD Exacerbation with Pneumonia

Provident has been engaged in ongoing DRG audits since ICD-10 was implemented in October 2015. We have identified potential DRG audit target areas related to our audit work, changes to the ICD-10 codeset, and Coding Clinic updates. We will be posting cases regularly in our newsletter. Please see this edition’s case below:

Case Summary:

Patient is a 65-year-old smoker who presented to Emergency Department with severe respiratory distress requiring Bi-PAP and was diagnosed with COPD exacerbation, respiratory acidosis and pneumonia likely due to MRSA (sputum culture positive for MRSA). ABGs on admission: pH = 7.23.

DRG Options:

COPD Exacerbation with Pneumonia

Audit Considerations & Strategies:

  • In ICD-9 either COPD exacerbation or pneumonia can be selected as the Principal Diagnosis (PDX) depending on the circumstances of the admission
  • In ICD-10, the COPD exacerbation or COPD with acute lower respiratory tract infection codes must be designated as the PDX
  • Bronchitis and pneumonia are both lower respiratory tract infections
  • Influenza is both an upper and lower respiratory infection
  • Even if a patient is admitted for pneumonia and only has a history of COPD (without exacerbation), the PDX is still COPD
  • When auditing ICD-10 cases, always confirm that COPD is sequenced as the PDX with pneumonia as a secondary diagnosis
  • For patients admitted with pneumonia and COPD exacerbation, a strategy would be to consider if acute respiratory failure is also present on admission (For a potential DRG shift by selecting acute respiratory failure as the PDX)
