Rupture of synovium, left toe(s)

This code indicates a tear or break in the synovial membrane surrounding a joint in the left toe(s). This typically results in pain, swelling, and impaired joint function due to the escape of synovial fluid. It represents an acute or chronic disruption of the joint capsule's inner lining.

Apply this code when documentation explicitly states a rupture of the synovium affecting one or more joints of the left foot's toes. This diagnosis is often supported by imaging studies such as MRI or ultrasound, and clinical findings like effusion or instability. Use for both traumatic and non-traumatic etiologies.

• Ensure laterality is clearly documented as "left toe(s)" to avoid unspecified coding.
• Distinguish from sprains/strains (S93.x) which involve ligaments or tendons, not primarily the synovium.
• Code any associated trauma (e.g., fracture) separately, following sequencing guidelines for multiple diagnoses.
