Q56: ICD10 Code for Indeterminate sex and pseudohermaphroditism

Q56 covers Indeterminate sex and pseudohermaphroditism, which include a range of congenital structural abnormalities of the reproductive organs present at birth, potentially impacting fertility, hormonal function, or anatomical development.

Symptoms

• Infertility – May result from malformations of the uterus, ovaries, or fallopian tubes (Q50–Q51)
• Absent or undescended testes – Characteristic of Q53 (undescended testicle)
• Abnormal penile opening – Seen in hypospadias (Q54)
• Ambiguous genitalia – Related to Q56 (indeterminate sex)
• Menstrual irregularities – Associated with uterine anomalies (Q51)

Diagnosis

Diagnosis of Indeterminate sex and pseudohermaphroditism often includes newborn physical examination, ultrasound imaging, MRI, genetic testing, and sometimes exploratory surgery to define internal reproductive anatomy.

ICD10 Code Usage

ICD10 code Q56 is crucial for documentation in EHRs, planning surgical corrections, fertility counseling, hormonal therapy planning, and insurance billing for congenital reproductive disorders.

Related Codes

• Q50 – Congenital malformations of ovaries, fallopian tubes and broad ligaments
• Q51 – Congenital malformations of uterus and cervix
• Q52 – Other congenital malformations of female genitalia
• Q53 – Undescended and ectopic testicle
• Q54 – Hypospadias
• Q55 – Other congenital malformations of male genital organs

FAQs

Q1: What is ICD10 code Q56?
A: It documents Indeterminate sex and pseudohermaphroditism, congenital anomalies affecting male or female reproductive organs.

Q2: Is surgical correction always necessary?
A: Not always, but many cases like hypospadias (Q54) or undescended testes (Q53) benefit from surgery for function and appearance.

Q3: Can these conditions affect fertility?
A: Yes, some congenital reproductive malformations can impact fertility without intervention.

Q4: What causes pseudohermaphroditism (Q56)?
A: It may result from genetic, hormonal, or developmental factors affecting sexual differentiation.

Q5: Are these detected during pregnancy?
A: Some anomalies may be suspected via prenatal imaging, but most are diagnosed postnatally.

Conclusion

ICD10 code Q56 plays a key role in documenting Indeterminate sex and pseudohermaphroditism, supporting early diagnosis, appropriate management, and multidisciplinary care for individuals with congenital genital anomalies.
