ICD10 code of Cutis marmorata telangiectatica congenita and ICD9 code

The ICD-10 code for Cutis marmorata telangiectatica congenita (CMTC) is Q82.5 (Congenital non-neoplastic nevus), while the older ICD-9-CM classification is 757.33 (Congenital pigmentary anomalies of skin). These codes are used by medical providers for billing and administrative purposes, though they are broad categories that encompass CMTC within the spectrum of congenital vascular anomalies.

What is Cutis marmorata telangiectatica congenita?

Cutis marmorata telangiectatica congenita is a rare, sporadic congenital vascular disorder characterized by a persistent, net-like (reticulated) bluish or violet skin discoloration. Unlike physiological cutis marmorata, which fades with warming, the vascular pattern of Cutis marmorata telangiectatica congenita remains visible regardless of temperature. The condition is usually present at birth and often affects the limbs, although it can manifest on the trunk or face. While many cases are isolated, Cutis marmorata telangiectatica congenita is sometimes associated with other developmental anomalies, such as limb asymmetry or ulcerations.

How is Cutis marmorata telangiectatica congenita diagnosed and coded?

Diagnosis of Cutis marmorata telangiectatica congenita is primarily clinical, based on the characteristic appearance of the skin lesions. Because there is no single specific laboratory test or genetic marker, physicians rely on physical examination to distinguish it from similar conditions like Klippel-Trenaunay syndrome. When coding for Cutis marmorata telangiectatica congenita, medical professionals use ICD-10 Q82.5; however, they may also append secondary codes to document associated findings, such as limb hypertrophy or atrophy, which are seen in a subset of patients.

What are the clinical features and associations of this condition?

While the skin manifestation is the hallmark of Cutis marmorata telangiectatica congenita, clinicians look for a range of potential systemic associations. It is essential to monitor for the following, which are common clinical considerations for patients:

• Limb asymmetry: Discrepancies in the length or circumference of the affected versus unaffected limb.


• Skin ulcerations: Occurring in approximately 10-20% of cases, primarily in early infancy.


• Vascular malformations: Potential involvement of deeper capillary, venous, or lymphatic systems.


• Developmental delays: Rare, but reported in cases where CMTC is part of a broader syndromic presentation.

Living with Cutis marmorata telangiectatica congenita

For the 55 people with Cutis marmorata telangiectatica congenita currently connected through the DiseaseMaps.org community, the experience often involves navigating uncertainty regarding prognosis. Most cases of Cutis marmorata telangiectatica congenita tend to fade or improve significantly during the first few years of life. However, the emotional impact of having a visible skin condition can be profound for families. Connecting with others who share this diagnosis can provide valuable peer support and practical advice on managing the skin's appearance and monitoring for associated symptoms.

Next steps

• Consult a pediatric dermatologist to confirm the diagnosis and establish a monitoring plan for potential limb asymmetry.


• Request a referral to a geneticist if there are concerns about syndromic associations or unusual clinical findings.


• Join the DiseaseMaps.org community to share experiences with others managing this condition.


• Keep a photographic record of the affected areas to help your physician track changes over time.
