What ICD-10 codes are used for abscess?

An abscess is a painful collection of pus caused by infection. Here are commonly used ICD-10-CM codes for various types of abscesses, along with brief clinical descriptions:

  • L02.91 - Cutaneous abscess, unspecified: Used for abscesses that occur in the skin but are not further specified in location.
  • L02.92 - Furuncle, unspecified: Applied when a furuncle, which is a type of abscess of a hair follicle, is diagnosed without specifying the location.
  • L02.93 - Carbuncle, unspecified: Utilized for carbuncles, which are larger and deeper skin abscesses, when the location is not further specified.
  • J85.0 - Abscess of lung: Used for lung abscesses, which are collections of pus within the lung tissue.
  • K61.0 - Anal abscess: Applied for perianal abscesses, localized collections of pus near the anal opening.
  • K12.2 - Intraoral (periodontal) abscess: Utilized for abscesses in the mouth, particularly in the periodontal or gum area.
  • L02.311 - Cutaneous abscess of right hand: Used when a cutaneous abscess is on the right hand.
  • L02.312 - Cutaneous abscess of left hand: Applied when a cutaneous abscess is on the left hand.
  • L02.32 - Cutaneous abscess of buttock: Utilized for cutaneous abscesses on the buttocks.
  • L02.39 - Other cutaneous abscess: Used for cutaneous abscesses occurring in areas not classified under more specific codes.

Which Abscess ICD Codes are billable?

The billable status of the mentioned ICD-10 codes for abscesses varies:

  • L02.91 - Cutaneous abscess, unspecified: Yes, billable. Medical expenses for unspecified cutaneous abscesses can be claimed.
  • L02.92 - Furuncle, unspecified: Yes, billable. Costs associated with unspecified furuncles can be reimbursed.
  • L02.93 - Carbuncle, unspecified: Yes, billable. Medical expenses for unspecified carbuncles can be claimed.
  • J85.0 - Abscess of lung: Yes, billable. Expenses for lung abscesses can be claimed.
  • K61.0 - Anal abscess: Yes, billable. Medical expenses for anal abscesses can be claimed.
  • K12.2 - Intraoral (periodontal) abscess: Yes, billable. Costs associated with intraoral abscesses in the periodontal area can be reimbursed.
  • L02.311 - Cutaneous abscess of right hand: Yes, billable. Medical expenses for cutaneous abscesses on the right hand can be claimed.
  • L02.312 - Cutaneous abscess of left hand: Yes, billable. Expenses for cutaneous abscesses on the left hand can be claimed.
  • L02.32 - Cutaneous abscess of buttock: Yes, billable. Medical expenses for cutaneous abscesses on the buttocks can be claimed.
  • L02.39 - Other cutaneous abscess: Yes, billable. Costs associated with other cutaneous abscesses can be reimbursed.

Clinical information

  • An abscess is a localized collection of pus within the subcutaneous tissue, composed of white blood cells, dead tissue, and bacteria, and is often categorized under cutaneous abscess, furuncle, and carbuncle.
  • Diagnosis involves a clinical evaluation, including assessing for redness, swelling, pain, and the presence of a fluctuant mass, which is typically found in areas such as the right axilla, right finger, right foot, left lower limb, and other sites.
  • Cutaneous abscesses, including furuncles and carbuncles, may be associated with cellulitis or acute lymphangitis, particularly when the infection spreads along lymphatic vessels or involves dermatoses.
  • Treatment usually requires incision and drainage to evacuate the pus and relieve pressure and pain, especially in cases of cutaneous abscess unspecified or those classified under other dermatoses cutaneous abscess.
  • Antibiotics may be prescribed if there is a concern about a local infection, systemic involvement, or if the abscess is located in high-risk areas such as rectal regions or the head (any part except sensitive structures), and diagnosis codes may be used to track these cases appropriately.
  • Patient education should include instructions on wound care, hygiene practices, and the importance of completing any prescribed antibiotics to avoid complications such as recurrent abscesses or progression to infective dermatitis.
  • Follow-up is often necessary to ensure healing and to address any persistent or recurrent cases of cutaneous abscess, furuncle, or carbuncle, especially if caused by a resistant infectious agent.
  • Referral to a specialist may be required for further evaluation and management when the abscess is complex, involves other diseases classified under skin infections, or arises in anatomically critical locations.

Commonly asked questions

An abscess is typically caused by a bacterial infection that leads to a localized buildup of pus. It often develops when bacteria enter the skin through a cut, hair follicle, or blocked gland. In some cases, the condition may occur alongside acute lymphangitis cellulitis, indicating a more widespread or deeper infection.

Treatment for an abscess usually involves incision and drainage to release the pus and reduce pressure. Antibiotics may be prescribed if there's surrounding cellulitis, acute lymphangitis, or if the infection is severe or spreading.

Yes, abscesses can recur, especially if the underlying cause—such as poor hygiene, chronic skin conditions, or persistent bacterial colonization—is not addressed.
