About coding premature puberty
The ICD-10-CM code for premature puberty is E30.1 (Precocious puberty). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on E30.1.
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.
