Lacerat extn musc/fasc/tend at forarm lv, unsp arm, init

This code signifies a tear or cut in an extensor muscle, its surrounding fascia, or a tendon located in the forearm. The injury affects an extensor structure other than the flexor carpi ulnaris, and the specific arm involved is not documented.

Apply this code when a patient presents with an acute laceration to an unspecified extensor muscle, fascia, or tendon in the forearm, such as the extensor digitorum or extensor carpi radialis. This is appropriate for the initial visit for this specific injury.

• Ensure documentation specifies "other" extensor muscle/tendon if not otherwise specified as a named extensor.
• Verify the encounter is indeed the "initial encounter" for this injury.
• If the laterality (left or right arm) is known, a more specific code should be used.
