About coding Adrenarche precocious
The ICD-10-CM code for Adrenarche precocious is E30.1 (Precocious puberty).
Within E30 (disorders of puberty, not elsewhere classified), E30.1 is specifically for Precocious puberty. Related codes cover delayed puberty (E30.0), other disorders of puberty (E30.8) and disorder of puberty, unspecified (E30.9).
Don't report E30.1 together with the conditions in its Excludes1 note: Albright (-McCune) (-Sternberg) syndrome (Q78.1), central precocious puberty (E22.8), congenital adrenal hyperplasia (E25.0), female heterosexual precocious pseudopuberty (E25.-) and 1 more.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for E30.1)
