ICD10 code of Ring Chromosome 14 Syndrome and ICD9 code

Ring Chromosome 14 Syndrome does not have a unique, dedicated ICD-10 or ICD-9 code. Clinicians typically use the general code Q93.2 (Chromosome mosaicism, not elsewhere classified) or Q93.5 (Other chromosome deletions) in ICD-10, and 758.3 in ICD-9, to document the chromosomal abnormality.

What is the clinical significance of Ring Chromosome 14 Syndrome?

Ring Chromosome 14 Syndrome is a rare chromosomal disorder characterized by the formation of a ring structure in the 14th chromosome. This structural change often leads to the loss of genetic material at the ends of the chromosome. The 22 members of the Ring Chromosome 14 Syndrome community on DiseaseMaps.org frequently report experiences with early-onset epilepsy, intellectual disability, and distinct facial features. Because the clinical presentation can vary significantly based on the amount of genetic material lost, diagnosis is typically confirmed via chromosomal microarray analysis or karyotyping.

How is Ring Chromosome 14 Syndrome classified for billing?

In medical coding, rare conditions like Ring Chromosome 14 Syndrome often fall under broader categories because there is no specific "ring chromosome" code. When submitting insurance claims or medical records, providers rely on the following classifications:

• ICD-10-CM: Q93.2 (Chromosome mosaicism) or Q93.5 (Other deletions of part of a chromosome).


• ICD-9-CM: 758.3 (Autosomal deletion syndromes).


• Orphanet Identifier: ORPHA:1685, which is the international standard for referencing Ring Chromosome 14 Syndrome in clinical research.

Is Ring Chromosome 14 Syndrome inherited?

In the vast majority of cases, Ring Chromosome 14 Syndrome occurs as a de novo (sporadic) event during the formation of reproductive cells or early embryonic development. It is rarely inherited from a parent, meaning the parents of a child with Ring Chromosome 14 Syndrome usually have normal chromosomes. Genetic counseling is highly recommended to explain the low recurrence risk and to understand the specific genetic deletion involved.

Next steps

• Consult with a clinical geneticist to review microarray results and understand the specific breakpoints of the ring chromosome.


• Connect with the 22 members on DiseaseMaps.org to share experiences regarding epilepsy management and developmental support.


• Schedule regular evaluations with a neurologist specialized in pediatric epilepsy.
