Superficial injury of elbow and forearm (S50) ICD-10-CM

About the S50 Code Range

ICD-10 code section S50 covers superficial injuries to the elbow and forearm, including contusions, abrasions, blisters, external constrictions, superficial foreign bodies, and insect bites. These codes specify details like injury location (right, left, or unspecified side), encounter type, and whether the injury has complications or sequelae.

This coding group is used primarily to classify minor skin and soft tissue injuries such as bruises (often recorded as contusions or hematomas), scrapes or friction burns (abrasions), and nonthermal blisters, which are sometimes associated with infection. For example, the ICD-10 code for "contusion of elbow" (S50.0) specifically identifies bruising in the elbow area, while the term "hematoma of elbow region" helps coders recognize synonyms linked to this code. Codes also include superficial foreign bodies like splinters or wood fragments embedded in the skin, indicated by codes starting with S50.35 for elbow and S50.85 for forearm. Nonvenomous insect bites to the elbow and forearm and other superficial bites are similarly detailed, with synonyms like "infected wound due to nonvenomous insect bite" further clarifying the diagnostic category. Encounter status (initial, subsequent, sequela) is indicated by a 7th character, guiding proper coding across treatment phases.
