Open wound of ankle, foot and toes (S91) ICD-10-CM

About the S91 Code Range

The ICD-10 code section S91 is used to categorize and report open wounds specifically located on the ankle, foot, and toes. These codes provide detailed classification to specify the type of open wound, its precise location, whether it involves foreign bodies, and the status of the injury encounter (initial, subsequent, or sequela).

This section includes codes for various open wound types such as lacerations, puncture wounds, and open bites, with further differentiation by laterality (right, left, unspecified) and nail involvement. For example, the ICD-10 code for an open wound of the right ankle with an unclear description is S91.001, which corresponds to synonyms like open fractures and dislocations of the right ankle also noted in the coding details. Similarly, lacerations without foreign bodies of the right ankle, often called simply "laceration of right ankle," are classified under code S91.011. The codes also cover puncture wounds that may or may not have foreign objects embedded, as well as open bite injuries from animal or human bites with or without damage to nails. These precise distinctions help medical coders accurately assign codes for billing and clinical documentation when dealing with complex lower limb injuries.
