Blister (nonthermal) of breast, unspecified breast, sequela

This code signifies a non-heat-related blister on an unspecified breast, indicating that the blister is a residual effect or complication of a previous injury or condition. It describes a healed or chronic state where the blister itself is no longer acute but its lasting impact is being addressed.

Use this code when documenting a patient presenting with a persistent or long-term consequence of a prior non-thermal breast blister, such as scarring, skin changes, or ongoing discomfort directly attributable to the original blister. This code is appropriate when the initial blister has resolved, but its sequelae require medical attention.

• Ensure documentation clearly links the current breast condition as a direct result or complication of a previously resolved non-thermal blister.
• Verify that the laterality of the breast is truly unspecified in the medical record; otherwise, a more specific code should be chosen.
• This "S" seventh character indicates a sequela, meaning the initial injury or condition has healed, and the current encounter addresses a residual effect.
