Sprain of interphalangeal joint of unsp great toe, init

This code signifies a sprain affecting the joint between the phalanges of the great toe, where the specific joint (proximal or distal) is not documented. It indicates an acute injury, meaning the patient is receiving initial treatment for this sprain.

Use this code when documentation confirms a great toe interphalangeal joint sprain, but the specific joint (e.g., IP joint) is not specified. This is appropriate for the initial visit or encounter for the injury.

• Ensure "unspecified" is clearly documented if the specific interphalangeal joint is unknown.
• Verify the encounter is indeed the "initial encounter" for this injury.
• Do not use if the sprain is to a metatarsophalangeal joint or another toe.
