Contradictory Documentation in Sepsis Coding
During a coding audit at a 350-bed hospital, you review 20 sepsis cases. In one case, the emergency department (ED) physician documents 'sepsis due to pneumonia' and orders antibiotics and fluids. The next day, the hospitalist documents 'pneumonia, resolved; no evidence of sepsis' and discontinues antibiotics. The discharge summary lists 'pneumonia' as the principal diagnosis and does not mention sepsis. The coding team assigned A41.9 (sepsis, unspecified) as the principal diagnosis and J18.9 (pneumonia) as secondary, based on the ED note. The case was billed at a higher DRG. The compliance officer asks you to assess whether this is a coding error or a documentation issue and to recommend corrective actions.
1. What is the most likely root cause of the discrepancy, and how should the auditor classify this finding?

The root cause is a lack of documentation reconciliation between the ED and inpatient providers, leading to conflicting clinical statements. The auditor should classify this as a documentation integrity issue rather than a pure coding error, because the coder followed the ED documentation but failed to query the discrepancy. The finding should be reported as a high-risk compliance issue because it affects DRG assignment and could be perceived as upcoding. The auditor should recommend implementing a query process when documentation conflicts, and educate providers on the importance of documenting resolved conditions and clarifying diagnoses at discharge.
2. What audit steps would you take to determine if this is an isolated incident or a systemic problem?
Read the worked answer
- Expand the sample: Review additional sepsis cases (e.g., 30–50) from the same period to identify patterns of conflicting documentation between ED and inpatient notes.
- Interview coders: Determine if they routinely query providers when documentation conflicts, and if they feel pressured to code from ED notes.
- Review query practices: Check if there is a formal query policy and whether queries are used consistently.
- Analyze data: Compare the hospital's sepsis coding rate and DRG distribution against benchmarks or peer hospitals.
- Educate providers: If a pattern exists, initiate education on documentation requirements and the impact on coding.
