E45

E45 — Retarded development following protein-calorie malnutrition

Billable / specific codeICD-10-CM

E45 is a billable, specific ICD-10-CM code for retarded development following protein-calorie malnutrition. It is valid for submission on a claim.

Inclusion terms

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

Nutritional short stature
Nutritional stunting
Physical retardation due to malnutrition

Other codes that can never be billed with E45

These codes carry an Excludes1 note pointing at E45. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E45 alone.

R62.5Other and unspecified lack of expected normal physiological development in childhood
E34.3Short stature due to endocrine disorder

Risk adjustment

E45 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

E45 is named in 3 Medicare coverage policies — 3 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
