🩺 CPT Code 42860: Excision of Tonsil Tags

Description

CPT 42860 is used to report the surgical excision of tonsil tags. A tonsil tag is a small piece of residual lymphoid tissue left behind in the tonsillar fossa after a previous tonsillectomy. These tags can become problematic, causing symptoms such as chronic sore throat, a sensation of a foreign body in the throat (globus sensation), bad breath (halitosis), or harboring debris leading to recurrent inflammation.

This procedure is considered a secondary procedure, as it is only performed on patients who have had a prior tonsillectomy. The excision is typically a minor procedure that can often be performed in an office setting under local anesthesia. The surgeon identifies the tag of tissue and removes it using techniques like sharp dissection (scalpel or scissors) or cautery. The primary goal is to remove the symptomatic tissue completely.

It is crucial to distinguish this from a secondary tonsillectomy (42820, 42821), which involves the removal of a significant amount of regrown or residual tonsil tissue, is more complex, and is usually performed under general anesthesia. Code 42860 is reserved for small, distinct tags.

CPT Code Details

  • wRVU (2024):
    • Facility: 1.73
    • Non-Facility (Office): 2.96
  • Assistant Surgeon Payable: No. The Medicare Physician Fee Schedule (MPFS) gives this code a payment indicator of ‘0’, meaning an assistant surgeon is not reimbursed.
  • Global Period: 10 Days. This means all typical pre-operative and post-operative care related to the procedure within 10 days of the surgery is included in the payment for the procedure itself and cannot be billed separately.
  • MS-DRG: This procedure is almost always performed in an outpatient setting and would not typically be assigned an MS-DRG. If performed during an inpatient stay for other reasons, it would likely fall under DRGs 146, 147, or 148 (Other Ear, Nose, Mouth & Throat O.R. Procedures) depending on the presence of Major Complications/Comorbidities (MCC) or Complications/Comorbidities (CC).

Code Tree (CPT Hierarchy)

Inclusions

The reimbursement for 42860 is considered to include the following components:

  • Application of local anesthesia.
  • Simple dissection and removal of the tonsil tag(s).
  • Use of cautery for hemostasis (controlling bleeding).
  • Simple closure of the mucosa, if necessary.
  • Immediate post-operative care and evaluation.

Exclusions

Do not use 42860 for the following procedures. They should be reported with different codes:

  • Primary Tonsillectomy: For patients under 12 (42825) or 12 and over (42826).
  • Secondary Tonsillectomy (removal of significant remnant): For patients under 12 (42820) or 12 and over (42821). The key difference is the amount and complexity of tissue removal.
  • Control of Post-Tonsillectomy Hemorrhage: If the primary procedure is controlling bleeding, use 42960-42962.
  • Biopsy of the Pharynx: If the primary intent is a biopsy of a suspicious lesion in the tonsillar fossa, consider codes like 42800 or 42804.
  • More complex procedures involving pharyngoplasty or extensive reconstruction.

Common ICD-10-CM Linkage

A CPT code must be linked to a supporting ICD-10-CM diagnosis code to establish medical necessity. Below are common examples.

J35.8: Other chronic diseases of tonsils and adenoids

  • Description: This code is frequently used to represent conditions like tonsillar remnants, tags, or chronic cryptitis in residual tissue. It is the most specific diagnosis for a symptomatic tonsil tag.
  • HCC (Hierarchical Condition Category): No

R07.0: Pain in throat

  • Description: Use this code when the primary presenting symptom is a sore throat caused by the tonsil tag. It can be used as a primary or secondary diagnosis to support medical necessity.
  • HCC (Hierarchical Condition Category): No

R13.10: Dysphagia, unspecified

  • Description: This code is appropriate if the patient’s chief complaint is difficulty swallowing or a sensation of food getting stuck due to the presence of the tonsil tag.
  • HCC (Hierarchical Condition Category): No

Z87.898: Personal history of other specified conditions

  • Description: This code is useful as a secondary diagnosis to indicate the patient’s history of a previous tonsillectomy, which is the prerequisite for having a tonsil tag. It provides important clinical context.
  • HCC (Hierarchical Condition Category): No

Coding Examples

Example 1: In-Office Excision

  • Scenario: A 45-year-old male with a history of tonsillectomy 20 years prior presents with a persistent “lump in the throat” sensation and halitosis. On examination, a 0.5 cm tag of lymphoid tissue is identified in the left tonsillar fossa. The physician applies local anesthetic and excises the tag with forceps and scissors in the office. Hemostasis is achieved with silver nitrate.
  • CPT Code: 42860
  • ICD-10-CM Codes:
    1. J35.8 - Other chronic diseases of tonsils and adenoids
    2. Z87.898 - Personal history of other specified conditions

Example 2: Distinguishing from Secondary Tonsillectomy

  • Scenario: A 22-year-old female with a history of tonsillectomy as a child presents with recurrent throat infections and significant sore throat. Examination reveals substantial regrowth of tonsil tissue in both tonsillar fossae, measuring over 2 cm on each side, with deep crypts. The physician takes the patient to the operating room, administers general anesthesia, and removes all the significant residual tissue.
  • Correct Coding: This is NOT coded with 42860. This is a more extensive procedure.
  • CPT Code: 42821 - Tonsillectomy, secondary; patient age 12 or over
  • ICD-10-CM Code: J35.8

Clinical Documentation & Billing Tips

  • Document the History: The note must clearly state that the patient has had a prior tonsillectomy.
  • Describe the Tag: Document the size, location (left/right tonsillar fossa), and appearance of the tonsil tag(s).
  • Specify the Symptoms: Clearly link the patient’s symptoms (e.g., globus sensation, pain, halitosis) to the presence of the tag. This establishes medical necessity.
  • Detail the Procedure: Describe the method of anesthesia (e.g., “local injection of 1% lidocaine with epinephrine”), the technique of excision (e.g., “excised with curved scissors”), and the method of hemostasis (e.g., “cautery,” “silver nitrate”).
  • Distinguish from Remnant: If the tissue is more than just a small “tag,” the documentation should reflect that to either justify 42860 for a small remnant or support a more complex code like 42821 if the removal was extensive.
