Foot drop, also known as drop foot, is a medical condition characterized by the inability to lift the front part of the foot. This condition isn’t a disease itself, but rather a sign of an underlying neurological, muscular, or anatomical problem. Accurate diagnosis and coding are crucial in healthcare, especially for conditions like foot drop that can stem from various causes. In the realm of medical coding, the ICD-10-CM system provides a standardized way to classify and code diagnoses. For right foot drop, the specific diagnosis code is M21.371.
Understanding the ICD-10-CM code M21.371 is essential for healthcare professionals involved in diagnosis, treatment, and billing. M21.371 falls under the category of “Acquired deformities of limbs,” specifically addressing “Foot drop (acquired).” The “1” at the end of the code denotes that the condition is specifically located in the right foot. This level of detail is vital for precise medical records and insurance claims. The code became effective on October 1, 2015, marking the initial year of the non-draft ICD-10-CM system, and the 2025 edition remains current as of October 1, 2024. It’s important to note that M21.371 is the American ICD-10-CM version, and international versions might have variations.

While M21.371 specifically refers to right foot drop, it’s useful to understand its place within the broader ICD-10-CM coding structure. The term “foot drop” itself is represented by the code M21.37, with further specifications to differentiate between right (M21.371), left (M21.372), and unspecified foot (M21.379). This detailed classification ensures that medical documentation accurately reflects the patient’s condition. Synonyms for M21.371 include “Right foot drop” and “Bilateral foot drop” (though bilateral foot drop would typically involve both M21.371 and M21.372 or potentially M21.379 if unspecified bilaterally in some contexts).
For those navigating the complexities of medical coding and diagnosis, grasping the specifics of codes like M21.371 is paramount. It facilitates accurate record-keeping, proper billing for services, and contributes to a clearer understanding of patient demographics and health trends related to foot drop. Using the correct diagnosis code ensures that healthcare systems can function efficiently and patients receive the appropriate care and have their conditions accurately documented.
