Multiple myeloma (Kahler's disease, medullary plasmacytoma, myelomatosis, plasma cell myeloma).
Medical necessity for the diagnosis and treatment of multiple myeloma is established by the presence of signs, symptoms, and laboratory findings consistent with the disease.The medical record should clearly document the patient's clinical presentation, diagnostic test results, and the rationale for the chosen treatment plan.
Diagnosis and management of multiple myeloma typically falls under the purview of hematologists-oncologists.They are responsible for diagnosing the condition through various tests like bone marrow biopsies, blood tests, and imaging studies. They also determine the stage of the disease and develop a treatment plan, which may involve chemotherapy, radiation therapy, stem cell transplantation, or other targeted therapies.Ongoing monitoring and management of potential complications are also part of their responsibility.
In simple words: Multiple myeloma is a type of blood cancer that affects plasma cells, which are important for fighting infections. These cancerous plasma cells build up in the bone marrow and prevent normal blood cell production. This can cause bone pain, tiredness, anemia (low red blood cell count), and weakened immune system.
Multiple myeloma is a malignant neoplasm of plasma cells, a type of white blood cell normally responsible for producing antibodies.In multiple myeloma, these plasma cells become cancerous and accumulate in the bone marrow, interfering with the production of normal blood cells. This can lead to a variety of symptoms including bone pain, fatigue, anemia, and increased susceptibility to infections.
Example 1: A 65-year-old patient presents with persistent bone pain, fatigue, and recurrent infections.Blood tests reveal anemia and elevated calcium levels.A bone marrow biopsy confirms the diagnosis of multiple myeloma., A 70-year-old patient experiences a sudden onset of severe back pain and is found to have a compression fracture in the spine. Further investigations, including a bone marrow biopsy, lead to a diagnosis of multiple myeloma., During a routine checkup, a 55-year-old patient is found to have elevated protein levels in their blood.Further testing, including a bone marrow biopsy, reveals the presence of multiple myeloma, even though the patient is currently asymptomatic.
Documentation for multiple myeloma should include details of the patient's presenting symptoms, physical examination findings, laboratory results (including complete blood count, serum protein electrophoresis, and kidney function tests), imaging studies (such as X-rays, CT scans, or MRI scans), and bone marrow biopsy results. The stage of the disease should be documented based on the International Staging System (ISS) or the Revised International Staging System (R-ISS).
** Excludes1: solitary myeloma (C90.3-) and solitary plasmacytoma (C90.3-).For accurate coding, it is essential to distinguish between multiple myeloma and related conditions like monoclonal gammopathy of undetermined significance (MGUS) and smoldering multiple myeloma.
