Operation Definition

Restoring, to the extent possible, a body part to its normal anatomic structure and function

Procedure Overview

This family covers surgical repair of muscle tissue when no more specific root operation, such as resection or transfer, applies. Muscles throughout the body, from the biceps and quadriceps to the diaphragm and abdominal wall, can be torn, lacerated, ruptured, or weakened by trauma, disease, or prior surgery, and repair aims to close the defect and restore the muscle's normal structure and, as much as possible, its function.

A surgeon may suture a lacerated muscle after a knife wound, close a traumatic diaphragmatic hernia, or reinforce a weakened abdominal wall following a hernia that isn't addressed with mesh-specific coding. The approach can be open, percutaneous, or via percutaneous endoscopic technique depending on the injury's location and severity.

Because this root operation is a default when nothing else fits, it captures a wide range of everyday muscle-related fixes rather than one narrow procedure type, which is part of why it appears so frequently across trauma and general surgery encounters.

Anatomy & Axis Detail

Hip Muscle, Right

The right hip muscles, including the gluteal group, iliopsoas, and short external rotators, generate the power and stability needed for standing, walking, and hip joint containment. Repair is commonly performed for traumatic tears, avulsion injuries from the greater trochanter, or muscle disruption following prior hip surgery or hardware removal. Because this region sits close to the hip joint capsule and major neurovascular structures, the operative note should clearly indicate that the intervention targeted muscle tissue rather than joint capsule or tendon insertion, which may be documented and coded separately. As with other paired body parts, laterality is essential, since right hip muscle repair is reported independently of any comparable procedure performed on the left.

Approach: Percutaneous Endoscopic

Percutaneous Endoscopic combines a puncture through skin or mucous membrane with insertion of an endoscope to visualize the procedure internally, as in laparoscopic cholecystectomy. It is distinguished from plain Percutaneous by the presence of scope-guided visualization, and from Via Natural or Artificial Opening Endoscopic by its route being a new puncture rather than an existing orifice or stoma.

Coding & Documentation

Coders assign a Repair code from this family when documentation describes closing, suturing, or otherwise restoring a damaged muscle without a more specific objective like reinforcing with synthetic material, cutting out tissue, or moving a muscle to a new site. The operative note should identify the muscle involved, the nature of the defect (laceration, rupture, dehiscence), and the technique used to close it, since these details drive both the body part and approach characters.

The most common mistake is defaulting to Repair when the documentation actually supports a more specific root operation. A hernia repaired with mesh should usually be coded as Supplement, not Repair, and a muscle flap advanced to cover a defect elsewhere may qualify as Transfer. Coders also miss that Repair is meant to be a last resort, so failing to rule out Resection, Excision, or Reattachment first is a frequent audit finding. Another pitfall is selecting the wrong specific muscle body part when the operative note only describes a general region, requiring a query back to the surgeon.

Commonly Confused With

SupplementRepair is easily confused with Supplement, which applies when mesh or other reinforcing material is added to a muscle or fascial defect, most often during hernia repair.
ReattachmentIt is also confused with Reattachment, used when a muscle has been completely detached and is reconnected to its origin or insertion, and with Transfer, where a muscle or its portion is moved intact to serve a new function while keeping its own blood supply.
ExcisionExcision and Resection are distinct because they involve removing tissue rather than restoring it.
