About coding tall stature
The ICD-10-CM code for tall stature is E34.4 (Constitutional tall stature).
Within E34 (other endocrine disorders), E34.4 is specifically for constitutional tall stature. Related codes cover carcinoid syndrome (E34.0), other hypersecretion of intestinal hormones (E34.1), ectopic hormone secretion, not elsewhere classified (E34.2), short stature due to endocrine disorder (E34.3), androgen insensitivity syndrome (E34.5), other specified endocrine disorders (E34.8) and endocrine disorder, unspecified (E34.9).
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.
