Sprain of interphalangeal joint of right little finger, subs

This diagnosis code indicates a sprain of the joint between the phalanges of the right little finger. It signifies that the ligaments supporting this specific joint have been stretched or torn, and the patient is presenting for follow-up care after the initial injury.

This code is appropriate for encounters where a patient is receiving ongoing treatment, rehabilitation, or evaluation for a previously diagnosed sprain of the right little finger's interphalangeal joint. This includes visits for physical therapy, re-evaluation of healing progress, or management of persistent symptoms.

• Ensure documentation clearly specifies the right little finger and the interphalangeal joint.
• Confirm the encounter is for subsequent care, not the initial injury (which would use an 'A' seventh character).
• Verify laterality (right) is explicitly documented to avoid coding errors.
