What Q87 covers · when clinicians use it
ICD-10 code Q87 identifies Other specified congenital malformation syndromes affecting multiple systems in the U.S. ICD-10-CM clinical and billing record set. It sits within the Congenital Malformations chapter (Q00–Q99), the section that groups related diagnoses so providers, payers, and public-health agencies report them consistently. Clinicians and medical coders apply Q87 when an encounter's findings match the Other specified congenital malformation syndromes affecting multiple systems description, attaching it to the patient record so downstream insurance claims, payer audits, quality reporting, and epidemiological surveillance all reference the same standardized diagnosis. The ICD-10-CM is maintained by the Centers for Medicare & Medicaid Services and the CDC's National Center for Health Statistics, with an updated official code set released each U.S. fiscal year — always verify Q87 against the current CMS/CDC release and your payer's documentation guidance before final use. This page summarizes documentation context for Q87 and is a coding reference, not clinical, diagnostic, or billing advice.
Q87 refers to Other specified congenital malformation syndromes affecting multiple systems, encompassing congenital conditions that affect the skin, breast development, integumentary system, or involve multiple organ systems present from birth.
Symptoms
- Severe skin dryness and scaling – Hallmark of congenital ichthyosis (Q80)
- Fragile skin prone to blistering – Seen in epidermolysis bullosa (Q81)
- Breast asymmetry or absence – Congenital malformations of breast (Q83)
- Skin lesions and vascular anomalies – Associated with phakomatoses (Q85)
- Multiple birth defects – Seen in congenital syndromes (Q86–Q87)
Diagnosis
Diagnosis involves clinical evaluation, genetic testing, skin biopsy (for disorders like epidermolysis bullosa), imaging studies, and sometimes prenatal screening for congenital syndromes affecting multiple systems.
ICD10 Code Usage
ICD10 code Q87 is essential for accurate recording in EHRs, genetic counseling documentation, insurance coding, management of congenital skin and system-wide malformations, and research registries.

FAQs
Q1: What is ICD10 code Q87?
A: It documents Other specified congenital malformation syndromes affecting multiple systems, congenital malformations involving the skin, breast, or broader syndromic conditions.
Q2: Can ichthyosis be treated?
A: While it cannot be cured, skin hydration treatments, keratolytics, and specialized skincare help manage it.
Q3: What are phakomatoses?
A: A group of genetic disorders that often affect the skin, nervous system, and eyes (e.g., neurofibromatosis).
Q4: Are congenital breast anomalies serious?
A: They may affect appearance or function but usually do not impact overall health unless associated with broader syndromes.
Q5: What causes congenital syndromes due to exogenous factors?
A: Environmental exposures during pregnancy such as infections (e.g., rubella) or toxins can lead to syndromes (Q86).
Conclusion
ICD10 code Q87 ensures accurate documentation of Other specified congenital malformation syndromes affecting multiple systems, facilitating early intervention, specialized care, and long-term management of congenital conditions affecting skin, breast, or multiple systems.
