E30.1

E30.1 — Precocious puberty

Billable / specific codeICD-10-CM

E30.1 is a billable, specific ICD-10-CM code for precocious puberty. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

Albright (-McCune) (-Sternberg) syndrome (Q78.1)
central precocious puberty (E22.8)
congenital adrenal hyperplasia (E25.0)
female heterosexual precocious pseudopuberty (E25.-)
male isosexual precocious pseudopuberty (E25.-)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Precocious menstruation

Other codes that can never be billed with E30.1

These codes carry an Excludes1 note pointing at E30.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E30.1 alone.

N92Excessive, frequent and irregular menstruation
N93Other abnormal uterine and vaginal bleeding

Risk adjustment

E30.1 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Medicare coverage

E30.1 is named in 4 Medicare coverage policies — 4 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
