Inflammation is the body’s normal response to illness and infection. Inflammatory diseases refer to disorders of the immune system that result in inflammation. Inflammation can be either acute or chronic. While acute inflammation take only hours or days to cure, chronic inflammation such as cancer, diabetes, heart disease or asthma can last for months or years. Through improved testing and diagnosis, these disorders can be diagnosed in the earliest stages and appropriate treatment can be provided. Rheumatologists, allergists, immunologists and other specialists treating such inflammatory disorders can rely on an experienced medical billing and coding company to report those treated conditions in medical claims submitted to insurers.

Diagnosis may include lab tests and imaging tests such as x-rays, MRIs, and ultrasound to make a treatment plan. Treatment for inflammatory diseases may include medications like NSAIDs or corticosteroids, rest, exercise, and surgery to correct joint damage.

Here are the ICD-10 codes to report some common inflammatory diseases.

Coding inflammatory bowel disease and other disorders require good knowledge of the relevant diagnosis and procedure codes. Coders need to be up to date with the changing codes and standards to ensure accurate reporting of diagnostic details, which will help avoid denied and delayed claims. Specialists can consider taking support from coders in reliable medical coding outsourcing companies to ensure error-free claim submission.
