ICD Code M65.359

ICD code M65359 is used to identify the condition known as "Trigger finger" affecting an unspecified little finger. Trigger finger, medically referred to as stenosing tenosynovitis, is a condition where one of your fingers gets stuck in a bent position and may straighten with a snap, similar to a trigger being pulled and released. This particular code specifies that the condition is present in the little finger, but it does not specify whether it is on the left or right hand. This level of specificity is crucial for accurate diagnosis, treatment planning, and billing processes within healthcare facilities.
