ICD Code M65.00

ICD code M6500 is used to identify a medical condition characterized by an abscess of the tendon sheath at an unspecified site. An abscess in this context refers to a localized collection of pus that has accumulated within the tendon sheath, which is the protective covering surrounding a tendon. This condition can lead to pain, swelling, and impaired movement in the affected area. The term "unspecified site" indicates that the specific location of the abscess within the body has not been detailed in the medical documentation. This code is essential for healthcare providers to accurately document and communicate the diagnosis for treatment planning and billing purposes.

When to use the ICD code for an abscess of the tendon sheath, unspecified site:

1. Presence of a palpable mass: A noticeable swelling or lump in the area of the tendon sheath.

2. Localized pain: Patient reports pain in the affected area, particularly during movement or pressure.

3. Swelling and inflammation: Observable redness, warmth, and swelling around the tendon sheath.

4. Limited range of motion: Difficulty or discomfort when attempting to move the affected joint or tendon.

5. Fever or systemic symptoms: Patient may exhibit fever or other signs of systemic infection, indicating a more severe condition.

6. History of trauma or injury: Recent injury or trauma to the area that may have led to the development of the abscess.

7. Chronic conditions: Presence of underlying chronic conditions that may predispose the patient to infections, such as diabetes or immunosuppression.

8. Diagnostic imaging findings: Confirmation of an abscess through ultrasound, MRI, or other imaging modalities showing fluid collection in the tendon sheath.

For the ICD code M65.00, which pertains to an abscess of the tendon sheath at an unspecified site, the relevant CPT codes that may be applicable for treatment include:

1. 26010 - Incision and drainage of tendon sheath of hand or finger (e.g., for infection or abscess).

2. 26011 - Incision and drainage of tendon sheath of hand or finger, with or without synovectomy; complicated (e.g., multiple tendons involved).

3. 26111 - Excision of lesion of tendon sheath or joint capsule (e.g., cyst, mucous cyst, or ganglion), hand or finger.

4. 26160 - Excision of lesion of tendon sheath or joint capsule (e.g., cyst, mucous cyst, or ganglion), foot or toe.

These CPT codes are commonly used for procedures related to the treatment of tendon sheath abscesses and may vary based on the specific site and complexity of the condition. Always ensure that the selected CPT code accurately reflects the procedure performed and is supported by the clinical documentation.
