C75.2Malignant neoplasm of craniopharyngeal duct

C75.2 is the ICD-10-CM diagnosis code for malignant neoplasm of craniopharyngeal duct. It belongs to category C75 (malignant neoplasm of other endocrine glands and related structures), block C73-C75 (malignant neoplasms of thyroid and other endocrine glands) 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 C75 (malignant neoplasm of other endocrine glands and related structures), C75.2 is specifically for malignant neoplasm of craniopharyngeal duct. Related codes cover of parathyroid gland (C75.0), of pituitary gland (C75.1), of pineal gland (C75.3), of carotid body (C75.4), of aortic body and other paraganglia (C75.5), with pluriglandular involvement, unspecified (C75.8) and of endocrine gland, unspecified (C75.9).

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 643 (Endocrine Disorders with MCC, relative weight 1.6139), DRG 644 (Endocrine Disorders with CC, relative weight 1.0044) and DRG 645 (Endocrine Disorders without CC/MCC, relative weight 0.7459), in MDC 10 (Endocrine, Nutritional and Metabolic Diseases and Disorders), 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 194.3 (malignant neoplasm of pituitary gland and craniopharyngeal duct).
