Subluxation of interphalangeal joint of right thumb, sequela

This diagnosis code indicates a partial dislocation of a joint within the right thumb, specifically an interphalangeal joint, where the joint surfaces are no longer perfectly aligned but are still in contact. The "sequela" designation signifies that this subluxation is a residual effect or complication of a previous injury or condition, rather than an acute event.

Use this code when documenting a patient presenting with ongoing symptoms or a chronic condition related to a past subluxation of an interphalangeal joint in their right thumb. This would apply to situations such as chronic pain, instability, or limited range of motion resulting from an old injury. It should not be used for acute subluxations.

• Ensure documentation clearly states the subluxation is of the right thumb and specifically an interphalangeal joint.
• Verify that the medical record supports the "sequela" designation, indicating a chronic or residual condition from a prior injury.
• Do not use this code for acute or initial encounters for a subluxation; instead, use the appropriate acute subluxation code.
