What is the ICD-10 code for neuroendocrine carcinoid tumor of the lung?

The ICD-10 code for a malignant neuroendocrine carcinoid tumor of the lung is C7A.090. This code is used when the tumor is confirmed as malignant through histologic examination.

How do you code a benign carcinoid tumor of the lung?

A benign carcinoid tumor of the lung is coded as D3A.090, provided there is histologic confirmation of benign behavior and absence of invasion.

Code	Description	When to Use	Key Documentation
C7A.090	Malignant carcinoid tumor of bronchus and lung	Use for malignant carcinoid tumors of the lung, confirmed by pathology.	Mitotic count <10/2mm² No necrosis Histologic confirmation of malignancy
C7A.1	Malignant poorly differentiated neuroendocrine tumors	Use for poorly differentiated neuroendocrine carcinomas of the lung.	Mitotic count ≥10/2mm² Presence of necrosis Histologic confirmation of poor differentiation
D3A.090	Benign carcinoid tumor of bronchus and lung	Use for benign carcinoid tumors of the lung, confirmed by pathology.	Histologic confirmation of benign behavior Absence of invasion or metastasis

Documentation & Coding Risks

Avoid these common issues when documenting Neuroendocrine Carcinoid Tumor of Lung.

Omitting differentiation status in documentation.

Impact

Clinical: Leads to incorrect diagnosis classification., Regulatory: Non-compliance with documentation standards., Financial: Potential loss of reimbursement due to incorrect coding.

Mitigation

Include differentiation status in all pathology reports, Educate staff on documentation standards

Misclassification of neuroendocrine tumor as benign when malignant features are present.

Impact

Reimbursement: Incorrect classification can lead to reduced reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data affecting patient records.

Mitigation

Verify histologic reports for malignancy indicators such as mitotic count and necrosis.

Documentation Completeness

Impact

Incomplete documentation of tumor differentiation and mitotic count.

Mitigation

Implement standardized templates for pathology reports.
