ED Coding and Reimbursement Alert

The physician must decide if the procedure is simple or complicated

Appropriate reporting of foreign-body removal (FBR) can vary greatly depending on the type of foreign body, its anatomic location, and the depth from which the physician must remove it. Here are five case studies to help you find your way.

Case #1: No Incision Means No Separate FBR

The situation: While operating a metal lathe, the patient embeds several small metal filings in his shoulder. The physician inspects the wounds and, using tweezers, extracts the shards.

The solution: Because the physician did not create a separate incision to remove the foreign bodies, you cannot code an FBR. Rather, you should include the removal of the metal filings as a component of whatever E/M service the physician documents (for example, 99213, Office or other outpatient visit for the evaluation and management of an established patient ...).

The -what if- scenario: The patient received deep wounds when he was hit from flying debris from an exploding propane tank. The physician explores the open wounds, removes several pieces of debris, and debrides and closes the wounds.

In this case, the physician performed wound exploration (20100-20103) with removal of the foreign body, which you should report using the wound exploration code that best describes the anatomic location of the wound the physician explored (such as 20101, Exploration of penetrating wound [separate procedure]; chest). Removal of foreign bodies is included in wound exploration codes.
 
Case #2: Turn to Integumentary Codes for Removal Just Beneath Skin

The situation: The physician removes a small metal pellet embedded underneath the skin.

The solution: In this case, because the removal occurs from just beneath the skin, you should turn to 10120 (Incision and removal of foreign body, subcutaneous tissues; simple).

The -what if- scenario: As above, the physician removes a small metal pellet embedded beneath the skin, but in this case the wound is severely infected. In this case, the better code choice may be 10121 (- complicated).

Whether you should choose the -simple- or -complicated- code depends on your physician's clinical judgment: If the wound is infected, as in this case, or shows other complications, 10121 may be more appropriate than the -simple- code 10120.

Case #3: For Deeper Removal, Look to Musculoskeletal Codes

The situation: The patient in case study #1 removes the metal filings himself. After several weeks, his wounds heal, but one metal filing remains and has now become imbedded beneath the skin and into the muscle. The physician sees the patient and, through an incision, removes the foreign body from the patient's shoulder.

The solution: When reporting FBR from a musculoskeletal site (muscle or even bone), you must select the correct FBR code by anatomic location and depth.

The musculoskeletal portion of CPT (20000-29999) includes specific FBR codes for the shoulder, humerus (upper arm) and elbow, hip, femur (thigh region) and knee joint, and feet and toes. CPT further defines these codes according to depth (such as subcutaneous, deep or, in some cases, complicated).

Example: For FBR in the shoulder, you must select among codes 23330 (Removal of foreign body, shoulder; subcutaneous), 23331 (... deep [e.g., Neer hemiarthroplasty removal]) and 23332 (... complicated [e.g., total shoulder]). If the physician removes the foreign body from the subcutaneous tissue or anywhere else above the fascia, you would select 23330.

If the physician must go below the fascia, use 23331. In the case of a particularly complex procedure (such as when the whole shoulder area is involved), you should select 23332.

In case #2, your best code selection is 23331.

The -what if- scenario: The physician must remove a foreign body from just above the fascia near the navel.

Because CPT does not contain a specific code for FBR from the abdomen, you must select from between 20520 (Removal of foreign body in muscle or tendon sheath; simple) or 20525 (... deep or complicated). You would also select these codes for other -unlisted- areas, such as head, neck, flank, spine, wrist/forearm and fingers. In this case, you should select 20520 because the foreign body was not below the fascia.

Case #4: FBR From Stomach? Choose the 40000 Series

The situation: An 8-year-old swallows a small battery. Using an endoscope, the physician removes the foreign body from the child's stomach.

The solution: You will find FBR codes for endoscopic removal from the intestine, stomach, colon, rectum and other sites in CPT's Digestive System section (40000 series).

In this case, for example, you should report 43247 (Upper gastrointestinal endoscopy including esophagus, stomach and either the duodenum and/or jejunum as appropriate; with removal of foreign body).

The -what if- scenario: The physician cannot safely remove the foreign body from the child's stomach using the endoscope and must create an incision to retrieve the object.

The 40000 series also contains codes to report open explorations for FBR at specific sites. For example, the code for open FBR from the stomach -- and the correct code in this instance -- is 43500 (Gastrotomy; with exploration or foreign-body removal).

Case #4: Scope May Not Call for Separate Code

The situation: The physician manually removes a previously placed percutaneous endoscopic gastrotomy (PEG) tube.

The solution: Although the PEG tube is technically a foreign object (in other words, it is not a natural part of the patient's body), CPT classifies PEG tube removal as an incidental service and does not contain a code to describe the procedure. Therefore, the physician may report only appropriate-level E/M codes to describe his service.

The -what if- scenario: During a manual PEG tube removal, a piece of the tube breaks off. The physician must use the endoscope to retrieve the broken portion of the PEG tube from the patient's stomach.

In this case, you may use the endoscopic foreign-body removal code 43247.

Rationale: Although chapter 6 of the National Correct Coding Initiative stipulates, -CPT code 43247 is not to be reported for routine removal of therapeutic devices previously placed,- this is not a -routine removal.-

In this case, there is no way to remove the portion of PEG tube manually. Your documentation should make clear, however, the necessity of using the scope to retrieve the portion of the broken tube. Without documentation, the payer will likely reject the claim.
