Strain of musc/fasc/tend at thigh level, unsp thigh, subs

This code signifies a muscle, fascia, or tendon strain located in the thigh, but not specifically identifying which thigh (left or right) or the exact muscle group involved. The "D" suffix indicates that this is a subsequent encounter for the injury, meaning the patient is receiving routine care during the healing phase.

Use this code when a patient presents for follow-up care, such as physical therapy or re-evaluation, for a previously diagnosed thigh strain where the specific muscle or tendon was not documented or is not relevant for the current encounter. This applies to strains of muscles other than quadriceps, hamstrings, or adductors, or when the specific muscle is unknown.

• Ensure documentation clearly indicates a subsequent encounter for the injury.
• Avoid this code if a more specific muscle group (e.g., quadriceps, hamstring) or laterality (left/right) is documented.
• If the encounter is for initial treatment or a sequela, a different seventh character will be required.
