Medial epicondylitis, unspecified elbow

This code describes inflammation and pain on the inner aspect of the elbow, specifically at the medial epicondyle, without further specification of laterality. It is commonly known as "golfer's elbow" and results from repetitive stress or overuse of the forearm flexor muscles.

Use this code when documentation indicates medial epicondylitis affecting an unspecified elbow. This diagnosis is typically supported by physical examination findings such as tenderness over the medial epicondyle and pain with resisted wrist flexion or pronation. It is appropriate when the provider has not specified whether the condition affects the right or left elbow.

• Do not use this code if the laterality (right or left elbow) is specified in the medical record; instead, use the more specific codes M77.01 or M77.02.
• Ensure the documentation clearly states "medial epicondylitis" or "golfer's elbow" to support this diagnosis.
• Consider any associated conditions, such as tendinitis of the forearm flexors, which may require additional coding.
