Code First

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.

About the N22 Code Range

The ICD-10 code N22 is specifically used for identifying cases where urinary tract stones, or calculi, arise in the context of other underlying diseases. This code helps in capturing instances where the urinary tract calculus is a complication or manifestation related to a different primary condition.

The term “calculus of urinary tract in diseases classified elsewhere” refers to stones forming in parts of the urinary system, including kidneys, ureters, or bladder, due to or alongside other health issues not directly classified under urinary tract disorders. Using the ICD-10 code for urinary tract calculus N22 allows medical coders to accurately document when urinary stones are linked to broader medical problems, ensuring precise clinical records and targeted patient care.
