A subungual hematoma is found in which location?

A subungual hematoma specifically refers to a collection of blood that occurs underneath a toenail or fingernail. This condition often results from trauma, such as an injury to the nail bed, which can cause blood to accumulate between the nail plate and the underlying nail bed. The presence of this hematoma typically manifests as a dark, discolored area under the nail, which can be quite painful depending on the amount of blood trapped and the pressure it creates.

The other options do not accurately represent the location of a subungual hematoma, making the correct understanding of this clinical term crucial for accurate medical coding and diagnosis.
