M71.00 identifies an infectious abscess within a bursa when the affected site is not documented or cannot be determined from available records.

M71.08 identifies a purulent infection (abscess) of a bursa located at a site not captured by any other specific M71.0x subcode — meaning it falls outside the shoulder, elbow, wrist, hand, hip, knee, ankle, and foot laterality options in the M71.0 subcategory.

Infectious abscess affecting the bursal sacs at two or more anatomically distinct sites simultaneously, classified under other bursopathies in the musculoskeletal chapter.

A fluid-filled synovial cyst arising in the popliteal fossa (Baker's cyst) where the affected knee is not specified as right or left in the documentation.
