Unspecified subluxation of right patella, initial encounter

This diagnosis code indicates a dislocation of the right kneecap that has spontaneously returned to its normal position, but the specific type or direction of the subluxation is not documented. It signifies an incomplete or partial dislocation of the patella on the right side.

This code is appropriate for the initial visit where a patient presents with symptoms consistent with a right patellar subluxation, but the physician's documentation does not specify the exact nature or direction of the subluxation. It is used when the subluxation has reduced spontaneously or was reduced by the patient prior to medical evaluation, and further details are lacking.

• Only use this code when the documentation explicitly states "unspecified" or lacks further detail regarding the subluxation type.
• Ensure the encounter is the "initial encounter" for this specific injury.
• Always query the provider for more specific documentation if available, such as the direction of subluxation (e.g., lateral, medial).
