N63: Unspecified lump in breast

N63 refers to Unspecified lump in breast, encompassing benign breast disorders, inflammatory conditions, hypertrophy, unidentified breast lumps, other structural breast issues, and complications following reconstructive breast surgery.

Symptoms

• Breast pain or tenderness – Often seen in benign mammary dysplasia (N60)
• Redness, swelling, and fever – Signs of breast infection or mastitis (N61)
• Noticeable breast enlargement – Associated with hypertrophy (N62)
• Palpable breast lump – May be detected without clear diagnosis (N63)
• Asymmetry or deformity – In reconstructed breasts (N65)

Diagnosis

Diagnosis of Unspecified lump in breast involves clinical breast examination, imaging studies such as mammography or breast ultrasound, MRI for complex cases, and biopsy when malignancy cannot be ruled out based on physical exam or imaging findings.

ICD10 Code Usage

ICD10 code N63 is used by breast surgeons, oncologists, plastic surgeons, and primary care providers to document breast health concerns, manage benign and post-surgical conditions, and differentiate from malignant processes during clinical evaluation.

Related Codes

• N60 – Benign mammary dysplasia
• N61 – Inflammatory disorders of breast
• N62 – Hypertrophy of breast
• N64 – Other disorders of breast
• N65 – Deformity and disproportion of reconstructed breast

FAQs

Q1: What is ICD10 code N63?
A: It refers to Unspecified lump in breast, documenting a variety of non-cancerous and reconstructive issues affecting breast tissue.

Q2: What is benign mammary dysplasia (N60)?
A: A non-cancerous condition characterized by fibrocystic changes causing breast lumpiness, tenderness, and swelling.

Q3: What does an unspecified lump in the breast (N63) mean?
A: A lump has been detected but the precise nature (benign vs malignant) is not yet determined; further diagnostic workup is needed.

Q4: What are common causes of breast inflammation (N61)?
A: Causes include infections (mastitis), abscesses, or post-surgical complications.

Q5: How are these breast disorders managed?
A: Management depends on the underlying cause and may include antibiotics, drainage of abscesses, supportive care, surgical correction, or close monitoring with imaging follow-ups.

Conclusion

ICD10 code N63 facilitates structured documentation, timely diagnosis, and management of Unspecified lump in breast, helping differentiate benign from serious breast conditions and optimize patient outcomes in breast health care.
