Sprain of ligaments of lumbar spine, sequela

This code signifies a chronic or late-effect sprain of the ligaments supporting the lumbar spine. It indicates that symptoms or conditions related to a previous lumbar ligament sprain are still present and being addressed.

Use this code when documenting ongoing pain, instability, or other residual issues directly attributable to a past lumbar ligament sprain. This is appropriate for follow-up encounters where the initial injury has healed, but its long-term consequences are being managed.

• Requires a seventh character "S" to indicate sequela.
• Always link to a definitive diagnosis of a previous lumbar ligament sprain in the patient's history.
• Do not use for acute or initial sprains; those require acute injury codes.
