Sprain of deltoid ligament of unspecified ankle, init encntr

This code signifies a sprain affecting the deltoid ligament, a strong ligament on the medial (inner) side of the ankle. It indicates an injury to this specific ligament without further specification of which ankle is affected. The "A" suffix denotes that this is the initial encounter for the injury.

Apply this code when documentation clearly states a sprain of the deltoid ligament, but the laterality (left or right ankle) is not specified. This is appropriate for the initial evaluation and treatment of such an injury. It should be used when the patient is first presenting for care related to this specific sprain.

• Ensure the documentation explicitly mentions the deltoid ligament; avoid using this code for general ankle sprains.
• Only use the "A" suffix for the initial encounter; subsequent encounters will require different seventh characters.
• If laterality is documented (left or right ankle), select a more specific code from the S93.42- series.
