Related ICD-10 Code Ranges
Complete code families applicable to Lung Infection
J12-J18Primary Range
Pneumonia due to various infectious organisms
This range includes codes for pneumonia caused by different pathogens, which is the primary concern in lung infections.
Respiratory failure, not elsewhere classified
This range is relevant for coding respiratory failure that may accompany severe lung infections.
Other sepsis
This range is used when sepsis is a complication of pneumonia, affecting coding and treatment strategies.

Compare key differences between these codes to ensure accurate selection
| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| J18.9 | Pneumonia, unspecified organism | Use when pneumonia is diagnosed but the specific pathogen is not identified. |
|
| J96.01 | Acute respiratory failure with hypoxia | Use when acute respiratory failure is documented alongside pneumonia. |
|
| A41.9 | Sepsis, unspecified organism | Use when sepsis is diagnosed without a specified organism. |

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 Lung Infection
Primary ICD-10-CM Codes for lung infection
Decision Criteria
clinical Criteria
- Presence of symptoms like cough, fever, and radiographic infiltrates
documentation Criteria
- Lack of specific pathogen identification
Applicable To
- Lung infection NOS
Clinical Validation Requirements
- Clinical diagnosis of pneumonia without specific pathogen identification
- Radiographic evidence of lung infiltrates
Code-Specific Risks
- Risk of under-coding if pathogen is identified but not documented
Coding Notes
- Ensure documentation specifies if the pneumonia is community-acquired or hospital-acquired.
J96.01 - Acute respiratory failure with hypoxia
Use when acute respiratory failure is documented alongside pneumonia.
Applicable To
- Hypoxic respiratory failure
Excludes
- Chronic respiratory failure (J96.10)
Clinical Validation Requirements
- SpO2 <88% or PaO2 <60 mmHg on ABG
Coding Notes
Document the severity and need for oxygen therapy.
A41.9 - Sepsis, unspecified organism
Use when sepsis is diagnosed without a specified organism.
Applicable To
- Septicemia NOS
Excludes
- Sepsis due to specific organisms (A40.-)
Clinical Validation Requirements
- SIRS criteria met with confirmed infection source
Coding Notes
Document the presence of organ dysfunction or failure.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Acute respiratory failure with hypoxia
J96.01Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Pneumonia due to Mycoplasma pneumoniae
J15.7Chronic respiratory failure, unspecified whether with hypoxia or hypercapnia
J96.10Sepsis due to Streptococcus, group A
A40.0Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Lung Infection to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code J18.9.
Impact
Clinical: May lead to inadequate treatment planning., Regulatory: Non-compliance with coding guidelines., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Ensure SpO2 levels and oxygen requirements are documented., Use templates to capture all necessary details.
Impact
Reimbursement: May lead to lower reimbursement rates., Compliance: Increases risk of audit due to lack of specificity., Data Quality: Reduces the quality of clinical data for research and analysis.
Mitigation Strategy
Ensure documentation includes pathogen details to use specific codes.
Impact
High risk of audit due to lack of specificity in pathogen documentation.
Mitigation Strategy
Implement mandatory pathogen identification protocols.
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.
