Contusion of diaphragm, sequela

This code signifies a persistent bruise or injury to the diaphragm muscle resulting from a previous trauma. It indicates that the initial acute injury has resolved, but the patient continues to experience symptoms or complications directly attributable to the past contusion. This is not an acute injury but rather a long-term effect.

Use this code when documenting a patient presenting with ongoing symptoms such as chronic pain, dyspnea, or diaphragmatic dysfunction that are directly linked to a previously sustained diaphragmatic contusion. This applies after the initial healing phase of the acute injury has passed and the condition is now considered a sequela.

• Always link this sequela code to an external cause code (V00-Y99) describing the original injury event.
• Ensure documentation clearly states the contusion is a past injury with current residual effects, not an acute event.
• Do not use this code for acute diaphragmatic contusions; those require codes from the S27.802A-S27.802D range.
