Glaucoma secondary to oth eye disord, unsp eye, stage unsp

This code signifies glaucoma that has developed as a consequence of another pre-existing ocular condition, where the specific eye affected and the stage of glaucoma are not documented. It indicates a secondary form of glaucoma, meaning it is not primary open-angle or angle-closure glaucoma, but rather a complication of another eye disease.

Use this code when the medical record clearly states glaucoma secondary to an underlying eye disorder, but the laterality (right, left, or bilateral) and the specific stage of glaucoma (e.g., mild, moderate, severe, indeterminate) are not specified. This code is appropriate when the documentation identifies the secondary nature of the glaucoma but lacks the granular detail for more specific codes.

• Always attempt to query for laterality and glaucoma stage to use a more specific code if possible.
• This code should be sequenced after the code for the underlying eye disorder causing the secondary glaucoma.
• Avoid using this code if the documentation specifies the affected eye or the stage of glaucoma; instead, select the appropriate H40.5x codes with greater specificity.
