Patient presents with a palpable right breast lump, prompting evaluation for breast mass, breast nodule, or possible breast cancer.  Chief complaint includes  discovery of a new lump in the right breast.  Onset, duration, and associated symptoms such as breast pain (mastalgia), nipple discharge, skin changes (e.g., dimpling, redness, peau d'orange), or axillary lymphadenopathy were documented.  Physical examination revealed a discrete palpable mass in the right breast.  The lump's characteristics including size, shape, mobility, tenderness, and location (upper outer quadrant, lower inner quadrant, etc.) were noted.  Patient's medical history, including family history of breast cancer, personal history of breast disease, hormonal status, and relevant risk factors, was reviewed.  Differential diagnosis includes fibroadenoma, breast cyst, lipoma, and malignancy.  Diagnostic workup may include breast imaging such as mammogram, ultrasound, or MRI.  Biopsy (e.g., fine needle aspiration, core needle biopsy) may be indicated for definitive diagnosis.  Treatment plan will be determined based on diagnostic findings and may involve surgical excision, observation, or other appropriate medical management.  Patient education regarding breast self-examination and follow-up care was provided.  ICD-10 codes (e.g., N63, D24) and CPT codes for procedures (e.g., 19100, 19200) will be applied as appropriate based on the final diagnosis and management plan.
