External constriction of part of breast, right breast, init

This code signifies an external compression or narrowing affecting the right breast. This constriction is caused by an external factor, rather than an internal anatomical issue, and is being addressed for the first time.

This code is appropriate for documenting a patient's initial presentation for a condition where an external force, such as tight clothing, a bra, or a medical device, is causing a constricting effect on the right breast. It should be used when the patient is first seen for this specific issue.

• Ensure documentation clearly specifies "right breast" and an "external" cause of constriction.
• Confirm this is the patient's first encounter for this specific breast constriction to justify the "A" (initial encounter) seventh character.
• Consider additional codes for the underlying cause of the external constriction if known and clinically relevant.
