External constrict of part of breast, unsp breast, sequela

This code indicates a long-term or late effect resulting from an external constriction affecting an unspecified part of the breast. This could be due to a previous injury, tight clothing, or other external pressure that led to a lasting physical change or symptom in the breast tissue. The specific breast (left or right) is not identified.

Use this code when documenting a chronic condition or residual effect of external breast constriction that is no longer acute. This is appropriate for follow-up encounters where the patient presents with ongoing issues directly attributable to a past external constrictive event. It signifies that the acute phase of the constriction has passed, but its consequences persist.

• Always assign an additional code to identify the specific nature of the sequela, if known (e.g., pain, deformity).
• Ensure the medical record clearly documents the causal link between the past external constriction and the current breast condition.
• This "S" seventh character indicates a sequela, meaning it's used for complications or conditions that arise as a direct result of an earlier injury or disease.
