How should glaucoma codes be assigned according to the text?
Assign as many codes as needed to identify the type of glaucoma, the affected eye, and the glaucoma stage.
How should bilateral glaucoma with the same type and stage be coded according to the text?
Report only the code for the type of glaucoma, bilateral, with the seventh character for the stage.
How should bilateral glaucoma with different types or stages be coded according to the text?
Report a code for each eye, specifying the type and stage for each eye.
How should bilateral glaucoma with different types be coded when the classification does not distinguish laterality?
Assign one code for each type of glaucoma with the appropriate seventh character for the stage.
When should a code for bilateral glaucoma be reported?
When the patient has bilateral glaucoma of the same type and stage.
What is the key difference in coding bilateral glaucoma with different types or stages compared to the same type and stage?
When the types or stages are different, you should report a code for each eye, but when they are the same, you should report a single bilateral code.
What is the key reason why the coding guidance differs for bilateral glaucoma with different types or stages compared to the same type and stage?
The difference in coding is to align with the structure of the classification system, which may or may not distinguish laterality.
When should a code for the type of glaucoma, rather than a bilateral code, be reported for bilateral glaucoma?
When the patient has bilateral glaucoma of the same type and stage, and there is no code for bilateral glaucoma.

Myocardial infarction with non-obstructive coronary arteries and microvascular disease
If a patient has a subsequent myocardial infarction of one type within 4 weeks of a myocardial infarction of a different type, how should it be coded?
Assign the appropriate codes from category I21 to identify each type, but do not assign a code from category I22
According to the guidelines, how should a code be assigned if a patient has bilateral glaucoma with the same type but different stages in each eye?
Assign a code for the type of glaucoma for each eye with the seventh character for the specific glaucoma stage documented for each eye.
What should be done if a patient is admitted with glaucoma and the stage progresses during the admission?
Assign the code for the highest stage of glaucoma documented during the admission.
When should the seventh character "4" for "indeterminate stage" be used for glaucoma?

Assign separate codes for hypertension and the heart condition.

When the provider has documented that the CKD is related to the hypertension.
How should hypertension with both heart and kidney involvement be coded?
Assign a code from combination category I13, Hypertensive heart and chronic kidney disease.
