Staphylococcal arthritis, unspecified knee

This code signifies an inflammatory joint condition of the knee caused by a Staphylococcus bacterial infection. It indicates a bacterial arthritis where the specific species of Staphylococcus is not documented, and the affected knee (left or right) is also unspecified.

Use this code when documentation confirms staphylococcal arthritis affecting the knee, but the laterality of the knee and the specific type of Staphylococcus are not specified. This code is appropriate when the physician's diagnosis explicitly states "staphylococcal arthritis of the knee" without further detail.

• Do not use if the specific Staphylococcus species (e.g., aureus, epidermidis) is identified; instead, use a more specific code from the M00.0- series.
• Avoid if the affected knee (right or left) is documented; choose M00.061 or M00.062 accordingly.
• Always review documentation for laterality and specific bacterial identification to ensure the highest level of specificity.
