Mech compl of internal left hip prosthesis, sequela

This code signifies a long-term or late-effect complication arising from a mechanical issue with an internal left hip prosthesis, other than those specifically classified elsewhere. These complications can include loosening, displacement, or fracture of components that manifest after the initial healing period. The "sequela" indicator denotes that the complication is a residual effect of a previous acute event or condition related to the prosthesis.

Use this code for patients presenting with chronic or late-onset mechanical problems of a left hip replacement that are not acute or initial complications. This applies when the patient is being treated for the lasting effects of a prior mechanical complication. Examples include chronic pain due to aseptic loosening, persistent instability after a dislocation, or ongoing issues from a component fracture that occurred in the past.

• This code requires a seventh character "S" for sequela, indicating the long-term nature of the complication.
• Do not use for acute or initial mechanical complications; those would typically use the "A" or "D" seventh character.
• Always code the specific nature of the mechanical complication (e.g., aseptic loosening, dislocation) as a primary diagnosis if known and applicable, in addition to this sequela code.
