About coding Craniopharyngioma
The ICD-10-CM code for Craniopharyngioma is D44.4 (Neoplasm of uncertain behavior of craniopharyngeal duct).
Within D44 (neoplasm of uncertain behavior of endocrine glands), D44.4 is specifically for neoplasm of uncertain behavior of craniopharyngeal duct. Related codes cover thyroid gland (D44.0), adrenal gland (D44.1), parathyroid gland (D44.2), pituitary gland (D44.3), pineal gland (D44.5), carotid body (D44.6), aortic body and other paraganglia (D44.7) and unspecified endocrine gland (D44.9).
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 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.
