About coding delayed menarche
The ICD-10-CM code for delayed menarche is E30.0 (Delayed puberty).
Within E30 (disorders of puberty, not elsewhere classified), E30.0 is specifically for delayed puberty. Related codes cover Precocious puberty (E30.1), other disorders of puberty (E30.8) and disorder of puberty, unspecified (E30.9).
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.
