Other bursal cyst, unspecified site

This code signifies the presence of a fluid-filled sac (cyst) within a bursa, which is a small, fluid-filled sac that reduces friction between bones, tendons, and muscles around joints. The "other bursal cyst" designation indicates it's not a specific type like a Baker's cyst, and "unspecified site" means the exact anatomical location of the cyst is not documented.

Use this code when documentation clearly states a diagnosis of a bursal cyst, but the specific type (e.g., ganglion, synovial) is not identified, and the anatomical location (e.g., shoulder, knee, elbow) is also not specified. This code is appropriate when the provider's notes lack the granular detail for more specific bursal cyst codes.

• Avoid using this code if the anatomical site of the bursal cyst is documented; instead, choose a more specific code from the M71.3- category.
• Query the provider for clarification on the specific type and site of the bursal cyst if possible to allow for more precise coding.
• Do not confuse this with codes for bursitis (M70.-) unless a cyst is explicitly documented in addition to inflammation.
