About D44.7
D44.7 is the ICD-10-CM diagnosis code for neoplasm of uncertain behavior of aortic body and other paraganglia. It belongs to category D44 (neoplasm of uncertain behavior of endocrine glands), block D37-D48 (neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes) 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 D44, choose D44.7 (aortic body and other paraganglia) only when documentation doesn't support a more specific option: thyroid gland (D44.0), adrenal gland (D44.1), parathyroid gland (D44.2), pituitary gland (D44.3), craniopharyngeal duct (D44.4), pineal gland (D44.5), carotid body (D44.6) 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 054 (Nervous System Neoplasms with MCC, relative weight 1.5194) and DRG 055 (Nervous System Neoplasms without MCC, relative weight 1.0296), in MDC 01 (Diseases and Disorders of the Nervous 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 237.3 (neoplasm of uncertain behavior of paraganglia).
