Inj/poisn/oth conseq of external causes comp preg, unsp tri

This code signifies that a pregnant patient has sustained an injury, poisoning, or other adverse consequence from an external cause, and this complication is impacting the pregnancy. It indicates that the specific trimester of the pregnancy at the time of the event is not documented or is unknown. This code is used when the external cause itself is also documented.

Use this code when a pregnant patient presents with an injury (e.g., fracture, burn, laceration), poisoning, or other sequelae of an external cause, and the medical record explicitly links this event to complicating the pregnancy. This code is appropriate when the documentation does not specify the trimester of pregnancy. Supporting documentation would include physician notes detailing the injury/poisoning and its impact on the pregnancy, along with the absence of trimester specification.

• Always code the specific nature of the injury or poisoning first, followed by this code.
• Also, code the external cause (e.g., fall, assault, accidental poisoning) from Chapter 20 of ICD-10-CM.
• Avoid using this code if the trimester is known; instead, select the more specific code for the relevant trimester (O9A.211, O9A.212, O9A.213).
