Unspecified subluxation of unspecified patella, sequela

This code indicates a long-term effect or complication resulting from a previous, unspecified subluxation of an unspecified patella. It signifies that the original injury has resolved, but residual symptoms or conditions persist. The specific details of the initial subluxation, such as the cause or laterality, are not documented or are unknown.

Apply this code when documenting a patient presenting with ongoing issues, such as chronic pain, instability, or functional limitations, that are directly attributable to a past patellar subluxation. This code is appropriate when the medical record does not specify which patella was affected or the exact nature of the initial subluxation. It is used for encounters where the sequela, not the acute injury, is being treated.

• Always assign a "S" (sequela) seventh character for conditions that are residual effects of a healed injury.
• Avoid using this code if the laterality (left or right) of the patella is documented; instead, use a more specific code.
• Ensure documentation clearly links the current condition to a previous patellar subluxation.
