Back pain ICD-10 refers to the specific diagnostic codes used in the International Classification of Diseases, 10th Revision, to document and bill for various types of back pain. The most commonly used code is M54.5, which represents "Low back pain." However, other related codes include M54.2 (Cervicalgia – neck pain), M54.6 (Thoracic spine pain), and M54.9 (Dorsalgia, unspecified). Accurate use of these ICD-10 codes is essential for proper medical documentation, insurance reimbursement, and effective treatment planning. These codes help healthcare providers communicate the nature of the condition to payers and ensure compliance with billing guidelines.
