Always document laterality for lung sites, Use templates to ensure completeness
Using C34.9 for metastatic lung cancer
Impact
Reimbursement: Incorrect DRG assignment may affect payment., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate data for cancer registry and research.
Mitigation
Use C78.00-C78.02 for secondary lung neoplasms.
Unspecified coding
Impact
Use of unspecified codes like C78.00 without primary site documentation.
Mitigation
Require documentation of primary site before coding.
