| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| K65.2 | Spontaneous bacterial peritonitis | Use when SBP is confirmed by paracentesis and linked to cirrhosis. |

| K65.1 | Peritoneal abscess | Use when an abscess is confirmed by imaging. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Essential facts and insights about Bacterial Peritonitis
Primary ICD-10-CM Codes for bacterial peritonitis
Decision Criteria
clinical Criteria
- Ascitic fluid neutrophil count ≥250 cells/mm³
documentation Criteria
- Link to cirrhosis or liver disease
Applicable To
- Spontaneous bacterial peritonitis in cirrhosis
Clinical Validation Requirements
- Ascitic fluid neutrophil count ≥250 cells/mm³
- Absence of surgical source of infection
Code-Specific Risks
- Incorrectly coding without confirming neutrophil count
- Not linking to cirrhosis when applicable
Coding Notes
- Ensure documentation specifies 'spontaneous' and includes lab results.
K65.1 - Peritoneal abscess
Use when an abscess is confirmed by imaging.
Applicable To
- Intra-abdominal abscess
Excludes
- Spontaneous bacterial peritonitis (K65.2)
Clinical Validation Requirements
- Imaging confirming abscess
Coding Notes
Ensure imaging confirms abscess presence.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Bacterial Peritonitis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code K65.2.
Impact
Clinical: May lead to inappropriate treatment., Regulatory: Non-compliance with documentation standards., Financial: Potential for claim denials.
Mitigation Strategy
Always specify 'spontaneous' if applicable, Include lab results in documentation
Impact
Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure documentation includes ascitic fluid analysis with PMN count.
Impact
Coding SBP without proper documentation of PMN count and cirrhosis linkage.
Mitigation Strategy
Ensure all documentation requirements are met before coding.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
