The ICD-10 code for an acute transverse fracture in the metadiaphysis of the distal second metatarsal is S92.324A. This code specifically identifies a nondisplaced transverse fracture of the second metatarsal bone, with the "A" indicating that it is the initial encounter for the fracture. The code is constructed based on the anatomical location (second metatarsal), the type of fracture (transverse), and the fact that it's in the metadiaphyseal region of the distal portion of the bone. When documenting this diagnosis, it's essential to specify laterality (right or left foot) which would modify the code to S92.324A for the right foot or S92.325A for the left foot. If the fracture is displaced rather than nondisplaced, the code would change to S92.323A, as noted in general medical knowledge and coding guidelines 1, 2. The ICD-10 coding system allows for this level of specificity to ensure accurate medical documentation, appropriate treatment planning, and proper billing for healthcare services related to this specific fracture. Key considerations in managing such fractures include maintaining the metatarsal parabola, sagittal position of the metatarsal heads, and a congruent metatarsophalangeal joint, with most injuries treated nonoperatively but displaced fractures requiring surgical intervention to preserve normal gait biomechanics 2. It's also crucial to inspect adjacent metatarsals and joints, such as the Lisfranc articulation, especially in cases of multiple metatarsal fractures, which can influence clinical and functional outcomes 3. Given the potential for chronic midfoot pain and the importance of accurate diagnosis and treatment, the use of specific ICD-10 codes like S92.324A is vital for ensuring proper care and reimbursement 4, 5.
