Primary ICD-10-CM Codes for hypersensitivity pneumonitis
Decision Criteria
clinical Criteria
- Confirmed exposure to moldy hay with supporting clinical findings.
Applicable To
- Hypersensitivity pneumonitis due to moldy hay
Excludes
- Chemical pneumonitis (J68.0)
Clinical Validation Requirements
- Exposure to moldy hay
- BAL lymphocytosis >20%
- Positive serum antibodies to Micropolyspora faeni
Code-Specific Risks
- Incorrectly coding when the exposure is not moldy hay.
Coding Notes
- Ensure documentation specifies the antigen source and clinical findings.
J67.2 - Bird fancier's lung
Use when hypersensitivity pneumonitis is due to exposure to bird droppings.
Applicable To
- Hypersensitivity pneumonitis due to bird droppings
Excludes
- Chemical pneumonitis (J68.0)
Clinical Validation Requirements
- Exposure to bird droppings
- Positive serum precipitins to avian antigens
- HRCT showing ground-glass opacities
Coding Notes
Ensure documentation specifies the antigen source and clinical findings.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Hypersensitivity Pneumonitis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code J67.0.
Impact
Clinical: May lead to misdiagnosis or inappropriate treatment., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims or incorrect reimbursement.
Mitigation Strategy
Thoroughly document exposure history., Include all relevant test results.
Impact
Reimbursement: May lead to incorrect DRG assignment affecting reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases specificity and accuracy of health records.
Mitigation Strategy
Use the specific J67.x code that matches the documented antigen.
Impact
Audits may focus on the specificity of antigen documentation in hypersensitivity pneumonitis cases.
Mitigation Strategy
Ensure all documentation includes detailed antigen exposure and supporting clinical findings.
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.
