Sprain of interphalangeal joint of right middle finger, init

This diagnosis code signifies a ligamentous injury to the joint between the phalanges of the right middle finger. It indicates a stretching or tearing of the connective tissues stabilizing this specific finger joint. The "initial encounter" designation means this is the first time the patient is receiving active treatment for this particular injury.

Apply this code when documenting a patient presenting with pain, swelling, and limited range of motion in the interphalangeal joint of their right middle finger following a traumatic event, such as a hyperextension or jamming injury. This code is appropriate for the initial evaluation and management of the sprain.

• Ensure documentation specifies the right middle finger and the interphalangeal joint.
• Confirm the encounter is for the initial treatment of this specific injury, not a follow-up.
• Distinguish from fractures or dislocations, which have different ICD-10-CM codes.
