About C7A.093

C7A.093 is the ICD-10-CM diagnosis code for malignant carcinoid tumor of the kidney. It belongs to category C7A (malignant neuroendocrine tumors), block C7A (malignant 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 C7A.09 (malignant carcinoid tumors of other sites), C7A.093 is specifically for malignant carcinoid tumor of the kidney. Related codes cover tumor of the bronchus and lung (C7A.090), tumor of the thymus (C7A.091), tumor of the stomach (C7A.092), tumor of the foregut, unspecified (C7A.094), tumor of the midgut, unspecified (C7A.095), tumor of the hindgut, unspecified (C7A.096) and tumors of other sites (C7A.098).

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

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 656 (Kidney and Ureter Procedures for Neoplasm with MCC, relative weight 3.2786), DRG 657 (Kidney and Ureter Procedures for Neoplasm with CC, relative weight 1.8365), DRG 658 (Kidney and Ureter Procedures for Neoplasm without CC/MCC, relative weight 1.538), DRG 686 (Kidney and Urinary Tract Neoplasms with MCC, relative weight 1.7237), DRG 687 (Kidney and Urinary Tract Neoplasms with CC, relative weight 0.9957) and DRG 688 (Kidney and Urinary Tract Neoplasms without CC/MCC, relative weight 0.7333), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), 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 209.24 (malignant carcinoid tumor of the kidney).
