E30.0Delayed puberty

E30.0 is the ICD-10-CM diagnosis code for delayed puberty. It belongs to category E30 (disorders of puberty, not elsewhere classified), block E20-E35 (disorders of other endocrine glands) and chapter 4 (endocrine, nutritional and metabolic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

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.

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 259.0 (delay in sexual development and puberty, not elsewhere classified).
