Webbed fingers (simple syndactyly of fingers without synostosis).
Modifiers may be applicable depending on the circumstances and the specific procedure(s) performed. Consult local guidelines and payer requirements.
Surgical correction of webbed fingers may be medically necessary to improve hand function, prevent complications such as contractures, or improve cosmetic appearance. The decision for surgery should be based on the clinical evaluation and individual patient needs.Documentation should support medical necessity.
Diagnosis and possible surgical correction of webbed fingers.The physician's responsibility includes conducting a physical examination, ordering appropriate imaging studies (if necessary), counseling the patient and family regarding treatment options (surgical or nonsurgical), performing surgery if indicated, and managing post-operative care.

In simple words: Webbed fingers is a birth defect where two or more fingers are joined together by skin and possibly other tissues.It's a type of syndactyly, meaning the fingers are fused, but the bones aren't joined together.
Q70.1, Webbed fingers, refers to a congenital anomaly characterized by the fusion of two or more fingers. This condition is classified as simple syndactyly, meaning the fusion is limited to the soft tissues (skin and subcutaneous tissue) without bony involvement (synostosis).The condition is present at birth and may vary in severity, affecting the degree of fusion and the number of fingers involved.Accurate documentation should specify the fingers involved and the extent of fusion.
Example 1: A newborn infant presents with webbed second and third fingers on the right hand. The condition is diagnosed as simple syndactyly, without bony fusion., A 6-month-old child is evaluated for webbed fingers.Imaging reveals soft tissue fusion of the little and ring fingers of the left hand., A young adult is referred to a hand surgeon for assessment of webbed fingers before potential reconstructive surgery to improve hand function.
Detailed description of the affected fingers, specifying which fingers are involved, the extent of webbing (e.g., complete or partial fusion), and the presence or absence of bony involvement (synostosis).Include relevant physical examination findings and imaging results (if any).Surgical reports should detail the procedure performed, complications (if any), and post-operative course.
** This code is used for simple syndactyly of the fingers without bony fusion.If there is bony involvement (synostosis) or if the webbing involves the toes, different ICD-10 codes should be used.The presence or absence of synostosis is crucial for correct coding.
