Code Classification

  • Diseases of the genitourinary system
    (N00–N99)
    • Diseases of male genital organs
      (N40-N53)
      • Disorders of male genital organs in diseases classified elsewhere
        (N51)

N51 is a billable diagnosis code used to specify a medical diagnosis of disorders of male genital organs in diseases classified elsewhere. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

This code is applicable to male patients only. It is clinically and virtually impossible to use this code on a non-male patient.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Chylocele
  • Chylocele of tunica vaginalis caused by Loa loa
  • Epididymitis associated with another disorder
  • Infection by Loa loa
  • Infection caused by Loa
  • Male genital organ disorder associated with another disorder
  • Orchitis associated with another disorder

Clinical Classification

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Code First

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.
  • underlying disease, such as:
  • filariasis B74.0 B74.9

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • amebic balanitis A06.8
  • candidal balanitis B37.42
  • gonococcal balanitis A54.23
  • gonococcal prostatitis A54.22
  • herpesviral herpes simplex balanitis A60.01
  • trichomonal prostatitis A59.02
  • tuberculous prostatitis A18.14

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:

  • Diagnoses for males only - The Medicare Code Editor detects inconsistencies between a patient’s sex and any diagnosis on the patient’s record, these edits apply to MALES only .
  • Manifestation diagnoses - Manifestation codes describe the manifestation of an underlying disease, not the disease itself, and therefore should not be used as a principal diagnosis.

Convert N51 to ICD-9-CM

  • ICD-9-CM Code: 608.81 - Male gen dis in oth dis
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education


Penis Disorders

Problems with the penis can cause pain and affect a man's sexual function and fertility. Penis disorders include:

  • Erectile dysfunction - inability to get or keep an erection
  • Priapism - a painful erection that does not go away
  • Peyronie's disease - bending of the penis during an erection due to a hard lump called a plaque
  • Balanitis - inflammation of the skin covering the head of the penis, most often in men and boys who have not been circumcised
  • Penile cancer - a rare form of cancer, highly curable when caught early

Testicular Disorders

Testicles, or testes, make male hormones and sperm. They are two egg-shaped organs inside the scrotum, the loose sac of skin behind the penis. It's easy to injure your testicles because they are not protected by bones or muscles. Men and boys should wear athletic supporters when they play sports.

You should examine your testicles monthly and seek medical attention for lumps, redness, pain or other changes. Testicles can get inflamed or infected. They can also develop cancer. Testicular cancer is rare and highly treatable. It usually happens between the ages of 15 and 40.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
