Unspecified subluxation of unspecified radial head, sequela

This code indicates a persistent or late-effect condition of an unspecified, partial dislocation of the radial head, where the specific side (left or right) is not documented. It signifies that the original injury has healed, but there are ongoing symptoms or complications directly attributable to that past subluxation.

Use this code when documentation clearly states a sequela of a radial head subluxation, but the initial injury's laterality was not specified, or the current encounter does not provide that detail. This is appropriate for follow-up visits addressing chronic pain, limited range of motion, or other long-term issues stemming from the original, unspecified subluxation.

• Always sequence this 'S' code as a secondary diagnosis, following the primary code for the current manifestation of the sequela.
• Avoid using this code if the laterality of the radial head subluxation is known; instead, select a more specific code.
• Ensure the medical record explicitly links the current condition to a past radial head subluxation to justify the 'sequela' designation.
