CodeDescriptionWhen to UseKey Documentation
L08.9Unspecified local infection of the skin and subcutaneous tissueUse when the infection is present but specific details are not documented.
  • Presence of purulent discharge
  • Erythema and warmth around the wound
O86.01Infection of obstetric surgical wound, superficial incisional siteUse for superficial infections following obstetric procedures.
  • Erythema and purulence at the incision site
  • Post-obstetric surgical procedure

Clinical Decision Support

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

Applicable To

  • General wound infection

Excludes

  • Specific infections with known pathogens

Clinical Validation Requirements

  • Presence of purulent discharge
  • Erythema and warmth around the wound

Code-Specific Risks

  • May lead to under-coding if specific details are available but not documented.

Coding Notes

  • Ensure documentation supports the use of this unspecified code.

Ancillary Codes

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

Staphylococcus aureus as the cause of diseases classified elsewhere

B95.6
Use when culture confirms Staphylococcus aureus.

Methicillin-resistant Staphylococcus aureus (MRSA) as the cause of diseases classified elsewhere

B95.62
Use when MRSA is confirmed.

Differential Codes

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

Cellulitis of lower limb

L03.116
Use when infection spreads beyond the wound edges.

Infection following a procedure, deep incisional site

T81.42
Use for deep incisional infections.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Infected Wound to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code L08.9.

Impact

Clinical: Inadequate treatment planning., Regulatory: Non-compliance with documentation standards., Financial: Potential claim denials.

Mitigation Strategy

Use standardized templates for wound documentation.

Impact

Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with coding standards., Data Quality: Inaccurate clinical data representation.

Mitigation Strategy

Use 'wound' for traumatic injuries and 'ulcer' for chronic conditions.

Impact

Incorrect sequencing of infection and sepsis codes.

Mitigation Strategy

Regular training on updated coding guidelines.

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.

Example Documentation

Patient presents with a 3 cm erythematous area around the incision, purulent discharge noted.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Wound looks infected.
Good Documentation Example
3 cm × 2 cm wound with purulent drainage; culture positive for Pseudomonas aeruginosa.
Explanation
The good example provides specific measurements and culture results.
