Range Overview

high priority

The ICD-10 category J85-J86 encompasses codes for suppurative and necrotic conditions of the lower respiratory tract. These codes are used to document conditions such as abscess of lung and mediastinum (J85) and pyothorax (J86). The codes in this range are specific to the type of condition and its location, providing a detailed picture of the patient's respiratory health.

Key Usage Points:

  • Always code to the highest level of specificity.
  • Use additional codes to identify any associated conditions or manifestations.
  • Use combination codes when necessary to accurately depict the patient's condition.
  • Remember to code for any complications related to the condition.
  • Always verify the code in the Tabular List before finalizing.

Coding Guidelines

When to Use:

  • When a patient has an abscess of the lung or mediastinum.
  • When a patient has a pyothorax.
  • When a patient has a necrotizing pneumonia.
  • When a patient has a lung abscess due to aspiration.

When NOT to Use:

  • When the condition is not specifically suppurative or necrotic.
  • When the condition is not located in the lower respiratory tract.
  • When the patient has a condition that is excluded from this range.
  • When the condition is a complication of a procedure.

Code Exclusions

Always verify exclusions in the Tabular List to ensure accurate coding.

Documentation Requirements

Proper documentation is crucial for accurate coding. It should include a clear description of the condition, its location, any associated conditions or complications, and the patient's overall health status.

Clinical Information:

  • Detailed description of the condition
  • Location of the condition
  • Any associated conditions or complications
  • Patient's overall health status

Supporting Evidence:

  • Radiological findings
  • Laboratory test results
  • Clinical notes from the treating physician
Good Documentation Example:

Patient diagnosed with abscess of right lung due to aspiration pneumonia. CT scan confirms diagnosis.

Poor Documentation Example:

Lung abscess.

Common Documentation Errors:

  • Not documenting the location of the condition
  • Not including supporting evidence
  • Not specifying associated conditions or complications
  • Using non-specific terminology

Coding Complexity

Medium
Complexity Rating

The complexity of these codes is medium due to the need to understand the specific conditions included, identify associated conditions or complications, use the correct combination codes, and navigate exclusions.

Key Factors:
  • Understanding the specific conditions included in this range
  • Identifying associated conditions or complications
  • Using the correct combination codes
  • Navigating exclusions

Specialty Focus

These codes are most commonly used by pulmonologists and thoracic surgeons. They may also be used by general practitioners and internists.

Primary Specialties:
Pulmonology
60%
Thoracic Surgery
30%
Clinical Scenarios:
  • Patient with aspiration pneumonia develops a lung abscess.
  • Patient with a history of IV drug use presents with pyothorax.
  • Patient with necrotizing pneumonia requires surgical intervention.
  • Patient with chronic lung disease develops a mediastinal abscess.

Frequently Asked Questions

Can I use a J85-J86 code for a condition that is a complication of a procedure?

No, these codes should not be used for conditions that are complications of procedures. Instead, use the appropriate complication code.
