2026 ICD-10-CM Diagnosis Code A54.9

Gonococcal infection, unspecified

ICD-10-CM Code:
A54.9
ICD-10 Code for:
Gonococcal infection, unspecified
Is Billable?
Yes - Valid for Submission
Chronic Condition Indicator: [1]
Not chronic
Code Navigator:

A54.9 is a billable diagnosis code used to specify a medical diagnosis of gonococcal infection, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2025 through September 30, 2026.

Unspecified diagnosis codes like A54.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Approximate Synonyms

The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear.

Clinical Classification

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

Sexually transmitted infections (excluding HIV and hepatitis)

CCSR Code: INF010

Inpatient Default: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.

Outpatient Default: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

Patient Education


Gonorrhea

Gonorrhea is a sexually transmitted infection (STI). It is most common in young adults. The bacteria that cause gonorrhea can infect the genital tract, mouth, or anus. You can get gonorrhea during vaginal, oral, or anal sex with an infected partner. A pregnant woman can pass it to her baby during childbirth.

Gonorrhea does not always cause symptoms. In men, gonorrhea can cause pain when urinating and discharge from the penis. If untreated, it can cause problems with the prostate and testicles.

In women, the early symptoms of gonorrhea often are mild. Later, it can cause bleeding between periods, pain when urinating, and increased discharge from the vagina. If untreated, it can lead to pelvic inflammatory disease, which causes problems with pregnancy and infertility.

Your health care provider will diagnose gonorrhea with lab tests. Treatment is with antibiotics. Treating gonorrhea is becoming more difficult because drug-resistant strains are increasing. Correct usage of latex condoms greatly reduces, but does not eliminate, the risk of catching or spreading gonorrhea. If your or your partner is allergic to latex, you can use polyurethane condoms. The most reliable way to avoid infection is to not have anal, vaginal, or oral sex.

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.
