Notes

General instructions on how these codes are used.

From Chapter 4 (E00-E89) Endocrine, nutritional and metabolic diseases applies to 973 codes
  • All neoplasms, whether functionally active or not, are classified in Chapter 2. Appropriate codes in this chapter (i.e. E05.8, E07.0, E16-E31, E34.-) may be used as additional codes to indicate either functional activity by neoplasms and ectopic endocrine tissue or hyperfunction and hypofunction of endocrine glands associated with neoplasms and other conditions classified elsewhere.

Clinical InformationClinical

  • Dwarfism

    a genetic or pathological condition that is characterized by short stature and undersize. abnormal skeletal growth usually results in an adult who is significantly below the average height.

Patient EducationClinical

Growth Disorders

Does your child seem much shorter - or much taller - than other kids his or her age? It could be normal. Some children may be small for their age but still be developing normally. Some children are short or tall because their parents are.

Questions About E34.328Overview

What is the ICD-10 code for other genetic causes of short stature?

The ICD-10-CM code for other genetic causes of short stature is E34.328 (sometimes written as E34328). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is E34.328 (Genetic causes of short stature) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other genetic causes of short stature on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does E34.328 group to?

When other genetic causes of short stature is the principal diagnosis on an inpatient stay, it groups to MS-DRG 644, 645, 643, with relative weights from 0.7461 to 1.6138 depending on complications. Higher weights mean higher Medicare reimbursement.

Can E34.328 be reported with Q77.4?

Not as a rule. The Excludes1 note at E34.3, which applies to E34.328, lists "achondroplastic short stature (Q77.4)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
