Unspecified subluxation of unspecified patella, subs encntr

This code signifies an unconfirmed displacement of the patella from its normal anatomical position, occurring after the initial treatment or diagnosis. It indicates a lack of specific detail regarding the cause, laterality, or precise nature of the subluxation. This diagnosis is typically used when the provider has not yet determined the specific type or cause of the patellar instability.

This code is appropriate for follow-up encounters where a patient presents with ongoing symptoms of patellar instability, and the specific type or cause of the subluxation remains undiagnosed. It can be used when a patient is returning for further evaluation, imaging, or conservative management of a previously identified but unspecified patellar subluxation. Avoid using this code if the laterality, specific type of subluxation (e.g., recurrent, traumatic), or cause has been determined.

• Always seek clarification from the provider if laterality or a more specific type of patellar subluxation is documented or implied.
• This code should be used sparingly and only when more specific codes are not supported by the documentation.
• For initial encounters, consider codes from S83.003A if the subluxation is unspecified.
