Impingement syndrome of unspecified shoulder

This code signifies a general diagnosis of shoulder impingement where the specific type or cause of the impingement is not documented. It indicates the compression of soft tissues (tendons, bursa) within the subacromial space, leading to pain and restricted movement, without further specification of the underlying pathology.

Use this code when documentation clearly states "shoulder impingement syndrome" but lacks details regarding the specific anatomical structure involved (e.g., rotator cuff, bursa) or the exact etiology. This code is appropriate when the provider has not specified laterality (left or right shoulder) or the specific type of impingement (e.g., primary, secondary).

• Avoid using this code if the documentation specifies the type of impingement (e.g., M75.41 for impingement syndrome of right shoulder, M75.42 for left shoulder).
• Always query the provider for greater specificity regarding laterality and the specific structures involved if possible, to allow for a more precise code assignment.
• This code should be used when the documentation is truly unspecified; do not assume laterality or type if not explicitly stated.
