ICD-10: E80.29

ICD-10 code E80.29 refers to "Other porphyria," which encompasses a variety of porphyrias that do not fall under the more commonly classified types. Porphyrias are a group of disorders caused by abnormalities in the heme production pathway, leading to the accumulation of porphyrins or their precursors in the body. This condition can result in a range of symptoms, including skin sensitivity, abdominal pain, and neurological complications.

Clinical Description of Other Porphyria (E80.29)

Overview of Porphyria

Porphyrias are classified based on the specific enzyme deficiency in the heme biosynthesis pathway. The main types include acute intermittent porphyria, porphyria cutanea tarda, and erythropoietic protoporphyria, among others. However, E80.29 is used for porphyrias that do not fit into these established categories, indicating a need for further classification or that they present with atypical features.

Symptoms

The symptoms of other porphyrias can vary widely depending on the specific type and the individual. Common manifestations include:

• Neurological Symptoms: These may include abdominal pain, neuropathy, seizures, and psychiatric symptoms such as anxiety or confusion.
• Cutaneous Symptoms: Some patients may experience photosensitivity, leading to skin lesions, blisters, or scarring upon exposure to sunlight.
• Gastrointestinal Symptoms: Abdominal pain, nausea, and vomiting are frequently reported, particularly in acute episodes.

Diagnosis

Diagnosis of other porphyrias typically involves:

• Clinical Evaluation: A thorough history and physical examination to assess symptoms and family history.
