CodeDescriptionWhen to UseKey Documentation
L02.211Cutaneous abscess of abdominal wallUse when the abscess is confined to the skin or subcutaneous tissue of the abdominal wall.
  • Imaging showing subcutaneous fluid collection
  • Clinical signs of erythema and fluctuance
K65.1Peritoneal abscessUse for abscesses located within the peritoneal cavity.
  • Imaging showing intraperitoneal fluid collection
  • Symptoms of fever and abdominal pain

Clinical Decision Support

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

Decision Criteria

clinical Criteria

  • Abscess located in the skin or subcutaneous tissue of the abdominal wall

Applicable To

  • Subcutaneous abscess of abdominal wall

Excludes

  • Peritoneal abscess (K65.1)

Clinical Validation Requirements

  • Imaging showing subcutaneous fluid collection
  • Clinical signs of erythema and fluctuance

Code-Specific Risks

  • Confusing with intra-abdominal abscess codes

Coding Notes

  • Ensure documentation specifies the location as the abdominal wall to avoid incorrect coding.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Methicillin susceptible Staphylococcus aureus as the cause of diseases classified elsewhere

B95.61
Use to specify the causative organism if identified.

Methicillin resistant Staphylococcus aureus as the cause of diseases classified elsewhere

B95.62
Use to specify the causative organism if identified.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Peritoneal abscess

K65.1
Use K65.1 for abscesses located within the peritoneal cavity, not the abdominal wall.

Cutaneous abscess of abdominal wall

L02.211
Use L02.211 for abscesses confined to the abdominal wall.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Abdominal Wall Abscess to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code L02.211.

Impact

Clinical: May affect treatment decisions, Regulatory: Non-compliance with documentation standards, Financial: Potential loss of reimbursement for related services

Mitigation Strategy

Always document culture results when available, Include organism identification if applicable

Impact

Reimbursement: Incorrect coding can lead to improper reimbursement., Compliance: May result in non-compliance with coding standards., Data Quality: Affects the accuracy of clinical data.

Mitigation Strategy

Verify the location through imaging and clinical documentation.

Impact

Risk of audits due to non-specific documentation of abscess location

Mitigation Strategy

Use precise anatomical terms and confirm with imaging

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.

  • Procedure details
  • Culture results

Example Documentation

Post-op day 7: 4 cm indurated, tender mass at midline incision. Ultrasound confirms 3.5 cm subcutaneous abscess. I&D performed; 20 mL purulent drainage. Wound packed. Cultures pending.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Abscess drained.
Good Documentation Example
5 cm fluctuant, erythematous mass in right lower quadrant; ultrasound-guided aspiration yielded 10 mL purulent fluid. Culture: Staphylococcus aureus.
Explanation
The good example provides specific details about the abscess and procedure, supporting accurate coding.
