Anaphyl rct d/t milk /dair prod w tolerance to bkd milk,subs

This code signifies an anaphylactic reaction specifically triggered by milk and dairy products in a patient who has demonstrated tolerance to baked milk. The "subsequent encounter" indicates that this is not the initial diagnosis or treatment for this particular reaction.

Apply this code when a patient presents for follow-up care, management, or treatment of an anaphylactic reaction to milk, and their medical record clearly documents a history of tolerating baked milk. This would be used after the initial acute phase of the reaction has been addressed.

• Ensure documentation specifies "subsequent encounter" to justify this seventh character.
• Verify that the patient's history explicitly states tolerance to baked milk, as this differentiates it from a general milk allergy.
• Do not use for initial encounters or for anaphylaxis due to milk without documented baked milk tolerance.
