M71.311
ICD-10-CMThis code signifies the presence of a non-inflammatory, fluid-filled sac (cyst) within a bursa of the right shoulder joint. This condition typically results from chronic irritation or trauma, leading to an accumulation of synovial fluid. It is distinct from acute bursitis or other inflammatory bursal conditions.
Apply this code when documentation explicitly states a "bursal cyst" or "ganglion cyst" affecting the right shoulder. This diagnosis is appropriate when imaging (e.g., ultrasound, MRI) confirms a cystic lesion within a bursa, and there is no evidence of active infection or acute inflammation.
