Hypermobility syndrome

This code represents a generalized connective tissue disorder characterized by excessive joint range of motion beyond normal physiological limits, often without an underlying systemic rheumatological condition. Patients typically present with recurrent joint dislocations, subluxations, and chronic musculoskeletal pain due to ligamentous laxity.

Use this code for patients diagnosed with benign joint hypermobility syndrome (BJHS) or generalized joint hypermobility (GJH) when it is the primary reason for the encounter or a significant co-morbidity. Documentation should clearly indicate a diagnosis of hypermobility syndrome, often supported by a positive Beighton score or similar clinical assessment.

• Differentiate from localized joint instability (e.g., recurrent shoulder dislocation) which has more specific codes.
• Do not confuse with Ehlers-Danlos syndrome (EDS) unless the documentation explicitly states EDS, as hypermobility syndrome is a distinct, often less severe, condition.
• Consider sequencing this code as a primary diagnosis when hypermobility is the focus of treatment, such as physical therapy for joint stabilization.
