About D3A.090

D3A.090 is the ICD-10-CM diagnosis code for benign carcinoid tumor of the bronchus and lung. It belongs to category D3A (benign neuroendocrine tumors), block D3A (benign neuroendocrine tumors) and chapter 2 (neoplasms). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within D3A.09 (benign carcinoid tumors of other sites), D3A.090 is specifically for benign carcinoid tumor of the bronchus and lung. Related codes cover tumor of the thymus (D3A.091), tumor of the stomach (D3A.092), tumor of the kidney (D3A.093), tumor of the foregut, unspecified (D3A.094), tumor of the midgut, unspecified (D3A.095), tumor of the hindgut, unspecified (D3A.096) and tumors of other sites (D3A.098).

Use an additional code to identify any associated endocrine syndrome, such as: carcinoid syndrome (E34.00).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 180 (Respiratory Neoplasms with MCC, relative weight 1.7806), DRG 181 (Respiratory Neoplasms with CC, relative weight 1.0936) and DRG 182 (Respiratory Neoplasms without CC/MCC, relative weight 0.7439), in MDC 04 (Diseases and Disorders of the Respiratory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 209.61 (benign carcinoid tumor of the bronchus and lung).
