Sprain of interphalangeal joint of right lesser toe(s), init

This diagnosis code signifies a ligamentous injury to one or more of the small joints within the right second, third, fourth, or fifth toes. It indicates a stretching or tearing of the connective tissues supporting these interphalangeal joints, without a fracture or dislocation. The "initial encounter" designation specifies that this is the first time the patient is receiving active treatment for this specific injury.

Use this code for patients presenting with pain, swelling, and tenderness in the interphalangeal joints of their right lesser toes following an acute injury, such as stubbing their toe or a direct impact. This code is appropriate when clinical examination and imaging (if performed) confirm a sprain and rule out other injuries like fractures or dislocations. It should be applied during the period of active treatment for the sprain.

• Ensure documentation clearly specifies "right" lesser toe(s) and confirms a sprain of the interphalangeal joint(s).
• Verify that the encounter is indeed the initial visit for active treatment of this specific injury.
• Distinguish from sprains of the metatarsophalangeal joint or great toe, which have different codes.
