| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| J15.7 | Pneumonia due to Mycoplasma pneumoniae | Use when Mycoplasma pneumoniae is confirmed as the causative agent. |
|
| J16.0 | Chlamydial pneumonia | Use when Chlamydia pneumoniae is confirmed as the causative agent. |
|
| J18.9 | Pneumonia, unspecified organism | Use when the causative organism is not identified or confirmed. |

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 Walking Pneumonia
Primary ICD-10-CM Codes for walking pneumonia
Decision Criteria
clinical Criteria
- PCR or serology confirming Mycoplasma pneumoniae
documentation Criteria
- Detailed lab results and symptom documentation
Applicable To
- Walking pneumonia due to Mycoplasma
Excludes
- Pneumonia due to other specified bacteria (J15.8)
Clinical Validation Requirements
- PCR positive for Mycoplasma pneumoniae
- Cold agglutinin titer ≥1:64
Code-Specific Risks
- Incorrect use when organism is not confirmed
- Potential for lower reimbursement if unspecified
Coding Notes
- Ensure documentation specifies Mycoplasma pneumoniae with confirmatory lab results.
J16.0 - Chlamydial pneumonia
Use when Chlamydia pneumoniae is confirmed as the causative agent.
Applicable To
- Pneumonia due to Chlamydia pneumoniae
Excludes
- Pneumonia due to other specified organisms
Clinical Validation Requirements
- Positive IgM for Chlamydia pneumoniae
Coding Notes
Ensure Chlamydia pneumoniae is confirmed through appropriate testing.
J18.9 - Pneumonia, unspecified organism
Use when the causative organism is not identified or confirmed.
Applicable To
- Atypical pneumonia, organism unspecified
Excludes
- Pneumonia due to specific organisms
Clinical Validation Requirements
- Clinical diagnosis without confirmatory testing
Coding Notes
Use only when no specific organism is identified.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Walking Pneumonia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code J15.7.
Impact
Clinical: Misdiagnosis risk, Regulatory: Non-compliance with coding standards, Financial: Potential for reduced reimbursement
Mitigation Strategy
Ensure lab results are documented, Verify pathogen identification
Impact
Reimbursement: Lower reimbursement due to unspecified coding, Compliance: Increased risk of audit, Data Quality: Decreased accuracy in clinical data
Mitigation Strategy
Use J15.7 with lab evidence of Mycoplasma pneumoniae.
Impact
High audit risk when using unspecified codes without attempts to identify pathogen.
Mitigation Strategy
Document all attempts to identify causative organism.
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.
