Webbed toes; simple syndactyly of toes without synostosis.
Modifiers may apply to procedures performed, but not to the diagnosis code itself.
Surgical correction of webbed toes may be considered for functional or cosmetic reasons.This should be assessed on a case-by-case basis based on the extent of webbing and potential impact on gait and foot function.Medical necessity will vary by payer policy.
Diagnosis and treatment of congenital foot deformities, including surgical correction if necessary.May involve genetic counseling depending on the suspected etiology.
In simple words: Webbed toes is a birth defect where two or more toes are joined together by skin or tissue.This is a simple form where the bones aren't fused.
Q70.3, Webbed toes, refers to a congenital anomaly characterized by the fusion of two or more toes.This code specifically denotes simple syndactyly, meaning the toes are connected by soft tissue, without bony fusion (synostosis).The condition can affect one or more toes on either foot.Further specification may be needed based on the affected foot and number of toes involved.
Example 1: A newborn infant is diagnosed with webbed second and third toes on the right foot.The condition is confirmed by physical examination and imaging studies., A child presents with webbed toes, affecting the little toe and the next toe on the left foot.Surgical separation is planned, requiring pre-operative assessment and post-operative care., A patient with a family history of syndactyly presents for evaluation of webbed toes on both feet.Genetic counseling is recommended to assess recurrence risks.
Complete medical history, including family history of similar conditions.Physical examination documenting the affected toes, location, and extent of webbing.Radiographic imaging (X-rays) to rule out bony fusion.Surgical records (if applicable), including operative notes and pathology reports.
