2025 ICD-10-CM code B95.61
(Active) Effective Date: N/A Infectious Diseases - Bacterial and viral infectious agents Certain infectious and parasitic diseases Feed
Methicillin susceptible Staphylococcus aureus (MSSA) infection as the cause of diseases classified elsewhere.
Medical necessity for the treatment of MSSA infection is established by the diagnosis of the specific condition caused by the MSSA infection.
Clinicians should identify the specific disease caused by the MSSA infection and code it accordingly.B95.61 is a supplementary code and should not be the primary diagnosis.Treatment typically involves antibiotics, and the choice of antibiotic depends on the specific infection.Clinicians should also consider the possibility of complications such as bacteremia, pneumonia, endocarditis, osteomyelitis, and toxic shock syndrome.
In simple words: This code indicates that a person has an infection caused by MSSA bacteria, a type of staph infection that can be treated with common antibiotics. This code is used in addition to the code for the specific disease caused by MSSA, such as a skin infection or pneumonia.
This code identifies Methicillin Susceptible Staphylococcus aureus (MSSA) as the cause of a disease classified elsewhere.MSSA are bacteria commonly found on the skin. They are susceptible to methicillin and other beta-lactam antibiotics. MSSA infections range from mild skin infections (pimples, boils, impetigo, abscesses, cellulitis) to severe conditions like pneumonia, bloodstream infections (bacteremia), endocarditis (heart valve infection), osteomyelitis (bone infection), and toxic shock syndrome. Symptoms vary depending on the infection site and may include fever, aches, pains, and localized symptoms at the infection site.
Example 1: A patient presents with pneumonia confirmed by chest X-ray.Blood cultures identify MSSA as the causative organism.The codes J18.9 (Pneumonia, unspecified organism) and B95.61 would be used., A patient with a history of intravenous drug use develops osteomyelitis. Cultures identify MSSA. Codes M86.671 (Other chronic osteomyelitis, unspecified bone) and B95.61 would be used., A patient has a skin abscess. A culture of the abscess reveals MSSA. The code L02.41 (Cutaneous abscess, trunk) and B95.61 would be used.
Documentation should support the diagnosis of an MSSA infection. This typically includes positive culture results identifying MSSA.Documentation should also describe the condition caused by the MSSA infection, as B95.61 is used as a secondary code.
** Distinguish MSSA from MRSA (Methicillin-Resistant Staphylococcus aureus) infections. MRSA requires different antibiotic treatment.
