About coding aortic body tumor
The ICD-10-CM code for aortic body tumor is D44.7 (Neoplasm of uncertain behavior of aortic body and other paraganglia). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on D44.7.
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.
