2025 ICD-10-CM code D76
(Active) Effective Date: N/A Diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism - Other disorders of blood and blood-forming organs (D70-D77) Diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (D50-D89) Feed
Other specified diseases with participation of lymphoreticular and reticulohistiocytic tissue.
Medical necessity must be established by documenting the signs, symptoms, and diagnostic findings that justify the need for investigation and management of this rare condition. The documentation must clearly demonstrate the impact of the condition on the patient's health and the rationale for the chosen treatment approach.
Diagnosis and management often fall under hematology, immunology, or oncology, depending on the specific disease manifestation.Laboratory tests such as CBC, ESR, rheumatoid factor, peripheral blood smear, leukocyte alkaline phosphatase (LAP), bone marrow biopsy, and synovial biopsy may be necessary. Imaging studies like ultrasound, CT, and MRI of the chest and abdomen may also be performed. Treatment varies depending on the underlying cause and may include NSAIDs, steroids, chemotherapy, or surgical excision.
- Diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (D50-D89)
- D70-D77
In simple words: This code is used when a person has a rare blood disorder involving the lymph system and other tissues where immune cells are found.It's used when the specific condition doesn't have its own code. These disorders can range from mild to serious and affect various parts of the body, causing symptoms like pain, swollen lymph nodes, joint problems, skin rashes, infections, anemia, and lumps or sores.
This code represents other specified diseases involving both lymphoreticular and reticulohistiocytic tissues, which are not classified elsewhere.The lymphoreticular system includes lymph nodes, lymphatic vessels, thymus, spleen, and bone marrow.Reticulohistiocytic tissue involves tissues of the skin, joints, or nearly any organ. These diseases can be benign or malignant. Symptoms can include pain, enlarged lymph nodes, joint destruction, skin rash, infection, anemia, and nodules or lesions on the trunk and extremities.
Example 1: A patient presents with unexplained lymphadenopathy, joint pain, and recurring infections. After extensive workup excluding other diagnoses, a diagnosis of a rare, unspecified lymphoreticular and reticulohistiocytic disorder is made., A patient experiences persistent fevers, anemia, and organomegaly.Biopsy reveals involvement of both lymphoreticular and reticulohistiocytic systems, pointing towards a systemic disorder not otherwise specified., A patient with a history of skin lesions and bone pain undergoes further testing. The results indicate a complex interplay between the lymphoreticular and reticulohistiocytic systems, consistent with a rare, unclassified disease process.
Documentation should include detailed clinical findings, laboratory results (CBC, ESR, RF, peripheral smear, LAP, biopsy results), imaging findings (ultrasound, CT, MRI), and any other relevant diagnostic information that supports the diagnosis of a lymphoreticular and reticulohistiocytic disorder not captured by a more specific code.It is crucial to document why other, more specific codes were ruled out.
** This is a general code for unspecified diseases involving both lymphoreticular and reticulohistiocytic tissues. It is essential to thoroughly document the clinical picture, diagnostic workup, and rationale for using this code.Always prioritize using a more specific code if available.
