Extraocular muscle entrapment, unspecified, unspecified eye

This code signifies a condition where an extraocular muscle becomes trapped, restricting eye movement. This entrapment can be due to trauma, inflammation, or other causes, leading to diplopia, pain, and limited range of motion in the affected eye. The "unspecified" nature indicates that the specific muscle involved and the laterality of the eye are not documented.

Use this code when documentation confirms extraocular muscle entrapment but does not specify which muscle is affected or whether it's the right or left eye. This is often seen in initial assessments or when imaging is inconclusive regarding the exact muscle involved. Documentation should clearly state "extraocular muscle entrapment" without further detail.

• Avoid using this code if the specific extraocular muscle (e.g., medial rectus, inferior rectus) is identified in the documentation; use a more specific code from the H50.6- series.
• Do not use this code if the laterality (right or left eye) is specified; instead, select H50.681 or H50.682.
• Query the provider for more specific information regarding the affected muscle and laterality whenever possible to allow for more precise coding.
