Other lymphedema

This code signifies lymphedema that is not classified as primary, postmastectomy, or due to filariasis. It represents a chronic swelling, typically of an extremity, caused by an impaired lymphatic system resulting from various underlying conditions or acquired factors. The lymphatic dysfunction leads to an accumulation of protein-rich fluid in the interstitial tissue.

Use this code for documented cases of secondary lymphedema where the specific cause is not otherwise classified by more specific ICD-9-CM codes. This includes lymphedema resulting from trauma, infection (other than filariasis), radiation therapy (when not postmastectomy), or surgical interventions not related to breast cancer. Documentation should clearly state "other lymphedema" or describe a secondary cause not covered by more specific codes.

• Ensure the documentation specifies a secondary cause of lymphedema that does not fit into codes for primary, postmastectomy, or filarial lymphedema.
• Avoid using this code if a more specific ICD-9-CM code for lymphedema (e.g., 457.0 for postmastectomy) is applicable.
• Always sequence this code after the underlying condition or cause of the lymphedema, if known and still active.
