Lacerat msl/fasc/tnd post grp at thi lev, left thigh, subs

This code signifies a tear or cut involving the muscles, their surrounding fascia, and tendons located in the posterior compartment of the left thigh. This injury specifically refers to a subsequent encounter, meaning the patient is receiving follow-up care for a previously diagnosed and treated laceration.

Apply this code when documenting ongoing treatment, such as wound care, physical therapy, or follow-up evaluations, for a laceration of the hamstring muscles, their fascia, or tendons in the left thigh. This code is appropriate after the initial treatment of the acute injury has been rendered.

• Ensure documentation clearly specifies "left thigh" and "posterior muscle group" to support this code.
• Confirm the encounter is for follow-up care, not the initial treatment, to justify the "D" seventh character.
• Distinguish from contusions or strains; this code is for an actual laceration (tear/cut).
