Orchitis and epididymitis (N45)
ICD-10 codes N45 through N45.4 identify specific inflammatory conditions affecting the male reproductive organs, including orchitis, epididymitis, and related abscesses. These codes help accurately document and classify infections or inflammations of the testis and epididymis for clinical and billing purposes.
N45.1 corresponds to epididymitis, inflammation of the epididymis, also called chronic epididymitis or infective epididymitis. This code includes variations like acute epididymitis and spermatogenic granuloma of the epididymis. N45.2 covers orchitis, which is inflammation of the testis, including infective or chronic orchitis and abscesses within the testicular tissue. N45.3 is used for epididymo-orchitis, a combined inflammation of both epididymis and testis, sometimes linked with conditions such as mumps orchitis. Finally, N45.4 is designated for abscesses localized in the epididymis or testis, reflecting severe infections that may require distinct management. Recognizing these synonyms and precise code uses aids healthcare professionals in selecting the correct ICD-10 code for inflammatory male genital conditions.
Instructional Notations
Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Epididymitis
Inflammation of the EPIDIDYMIS. Its clinical features include enlarged epididymis, a swollen SCROTUM; PAIN; PYURIA; and FEVER. It is usually related to infections in the URINARY TRACT, which likely spread to the EPIDIDYMIS through either the VAS DEFERENS or the lymphatics of the SPERMATIC CORD.
Orchitis
Inflammation of a TESTIS. It has many features of EPIDIDYMITIS, such as swollen SCROTUM; PAIN; PYURIA; and FEVER. It is usually related to infections in the URINARY TRACT, which likely spread to the EPIDIDYMIS and then the TESTIS through either the VAS DEFERENS or the lymphatics of the SPERMATIC CORD.
