Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the Q62 range.
Retrocaval Ureter
A rare congenital abnormality resulting in the URETER passing dorsal to and being obstructed by the INFERIOR VENA CAVA.
Ureterocele
A cystic dilatation of the end of a URETER as it enters into the URINARY BLADDER. It is characterized by the ballooning of the ureteral orifice into the lumen of the bladder and may obstruct urine flow.
About the Q62 Code Range
ICD-10 code section Q62 covers congenital obstructive defects of the renal pelvis and malformations of the ureter, used to classify various birth-related abnormalities affecting urinary drainage. These codes specifically identify structural blockages, occlusions, or unusual formations present from birth that impact kidney and ureter function.
This code group includes conditions like Q62.0, congenital hydronephrosis, which denotes swelling of the kidney due to urinary obstruction and is also known as congenital megacalycosis or obstruction of the ureteral orifice. Other codes specify occlusion locations, such as Q62.11 for ureteropelvic junction obstruction and Q62.12 for ureterovesical orifice occlusion. The section also includes Q62.2 congenital megaureter, characterized by an abnormally dilated ureter sometimes linked to urine reflux. Malpositions like Q62.61 deviation of ureter and Q62.63 anomalous implantation are included as well. Conditions such as Q62.7 congenital vesico-uretero-renal reflux describe backward urine flow from the bladder to kidneys. Other codes address agenesis, duplication, and ureterocele malformations. These ICD-10 codes precisely capture congenital urinary tract blockages and deformities to aid diagnosis, treatment planning, and medical documentation effectively.
