What cyst ICD codes can I use?

Cyst ICD-10 codes cover a wide range of conditions affecting different body systems. Here are several common cyst codes you can use in clinical documentation:

  • L72.0 - Epidermal cyst: This ICD-10-CM code is used for patients with an epidermal inclusion cyst, also known as an epidermoid cyst. These are common in areas with hair follicles and may appear on the scalp, face, neck, and back.
  • L72.11 - Pilar cyst (Trichilemmal cyst): Often found on the scalp, these cysts are derived from the outer root sheath of hair follicles.
  • L72.2 - Steatocystoma multiplex: A rare disorder characterized by multiple sebum-containing cysts.
  • L72.3 - Sebaceous cyst: This ICD-10 code is used for a patient confirmed to have a sebaceous cyst, which forms under the skin. It can develop anywhere on the body, including the scrotum or vulva.
  • L72.8 - Other follicular cysts of skin and subcutaneous tissue: This code is used for specified follicular disorders not classified elsewhere.
  • L72.9 - Follicular cyst of skin and subcutaneous tissue, unspecified: This is used when the type of follicular cyst is not specified. It includes subcutaneous tissue and unspecified follicular cysts.

Are these cyst ICD codes billable?

Yes. All the aforementioned cyst-related ICD-10-CM codes are valid and billable. However, for optimal reimbursement, always code to the highest level of specificity documented in the medical record.

Clinical information about cysts

  • Cysts are closed sac-like structures that can be filled with fluid, pus, or other materials.
  • They may develop on any part of the body, from the skin and subcutaneous tissue to internal organs, appearing as a mass that ranges from microscopic to large structures that can displace organs.
  • This can be due to infectious diseases, pregnancy and childbirth complications, congenital malformations, or abnormalities in the chromosomes.
  • Diseases of the skin and subcutaneous tissue often include various types of cysts, which may be categorized under follicular cysts of the skin.
  • Depending on their location and size, some cysts may remain asymptomatic, while others can cause noticeable symptoms.
  • Symptoms may include localized pain and tenderness, swelling, and, in certain cases, infection if the cyst ruptures.
  • Most cysts are benign and do not lead to serious complications. However, certain types, such as those resulting from diseases classified elsewhere or disorder unspecified, may have significant health implications.
  • Diagnosis typically involves physical examination, imaging tests (like ultrasound, CT, or MRI), and, in some cases, biopsy for further analysis.
  • Treatment options vary based on the nature and location of the cyst. They might involve observation, drainage, medication, or surgical removal, especially if there's a risk of failure to resolve spontaneously.
