About coding goiter nontoxic adenomatous
The ICD-10-CM code for goiter nontoxic adenomatous is E04.9 (Nontoxic goiter, unspecified).
Within E04, choose E04.9 (Nontoxic goiter, unspecified) only when documentation doesn't support a more specific option: nontoxic diffuse goiter (E04.0), nontoxic single thyroid nodule (E04.1), nontoxic multinodular goiter (E04.2) and other specified nontoxic goiter (E04.8).
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.
