Anaphylactic reaction due to tree nuts and seeds, sequela

This code signifies a long-term or residual effect stemming from a past anaphylactic reaction caused by tree nuts or seeds. It indicates that the acute phase of the allergic reaction has resolved, but the patient continues to experience related health issues or complications.

Use this code when documenting conditions or symptoms that are a direct consequence of a previous anaphylactic episode due to tree nuts or seeds, and these conditions are no longer acute. This would apply to follow-up visits addressing chronic issues, such as persistent asthma exacerbated by the prior reaction, or ongoing management of related organ damage.

• Ensure the documentation clearly links the current condition to a past anaphylactic reaction from tree nuts or seeds.
• This code is for sequelae only; do not use it for acute or active anaphylaxis.
• Always assign additional codes to specify the nature of the sequela (e.g., specific organ damage, chronic respiratory condition).
