2026 ICD-10-CM Diagnosis Code N74

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.

Code Edits

The Medicare Code Editor (MCE) detects errors and inconsistencies in ICD-10-CM diagnosis coding that can affect Medicare claim validity. These Medicare code edits help medical coders and billing professionals determine when a diagnosis code is not appropriate as a principal diagnosis, does not meet coverage criteria. Use this list to verify whether a code is valid for Medicare billing and to avoid claim rejections or denials due to diagnosis coding issues.

MS-DRG Mapping for ICD-10-CM Code N74

Diagnosis-Related Groups (DRGs) are used to classify hospital cases for billing and healthcare management. They help standardize how hospitals and other providers are reimbursed for inpatient care. Patients are grouped based on their principal diagnosis into broader categories called Major Diagnostic Categories (MDCs).

Once assigned to a DRG, the hospital receives a set payment for the patient’s care, regardless of the actual services provided. This fixed rate is intended to cover the typical cost of treating patients within that group. The payment amount depends on the DRG's relative weight, which reflects the expected complexity and cost of care based on the severity of the patient’s condition.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V43.0 applicable from 10/01/2025 through 09/30/2026.

Convert N74 to ICD-9-CM

Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.

Pelvic Inflammatory Disease

What is pelvic inflammatory disease?

Pelvic inflammatory disease (PID) is an infection of the uterus, ovaries, and other female reproductive organs. PID causes scarring in these organs. This can lead to infertility, ectopic pregnancy, pelvic pain, abscesses (a collection of pus), and other serious problems. PID is the most common preventable cause of infertility in the United States.

What causes pelvic inflammatory disease?

Many types of bacteria can cause PID, but it's often caused by sexually transmitted infections (STIs). Gonorrhea and chlamydia are the most common causes of PID.

You are at greater risk for PID if you:

• Are sexually active and younger than age 25.
• Have more than one sex partner.
• Douche. Douching can push bacteria into your reproductive organs. It may also hide the signs of PID.
• Have an STI and do not get treated.
• Have had PID or an STI before.

It's not as common, but sometimes using an intrauterine device (IUD) for birth control can increase your risk for PID. However, your risk is usually only during the first three weeks after the IUD is placed inside your uterus.

What are the symptoms of pelvic inflammatory disease?

If you have PID, you may have mild or no symptoms. If you do have symptoms, the most common symptom is pain in the lower abdomen (belly). Other symptoms can include:

• Fever
• Foul-smelling vaginal discharge
• Bleeding between periods
• Pain or bleeding during sex
• Painful urination (peeing)

See your health care provider if you have any symptoms of PID or if you think you or your partner were exposed to an STI. Early treatment is important. Waiting too long for treatment increases the risk of infertility.

How is pelvic inflammatory disease diagnosed?

There is no one test for PID. To check for PID, your provider may:

• Ask about your medical and sexual history
• Review your symptoms
• Do a pelvic exam
• Order blood, urine, and imaging tests

What is the treatment for pelvic inflammatory disease?

Antibiotics are used to treat PID. You must take all the medicine, even if your symptoms go away to make sure the infection is cured. You will likely need to follow up with your provider to make sure the treatment is working.

Tell your recent sex partner(s) so they can get tested and treated. Don't have sex until you finish treatment, otherwise you can reinfect each other.

If you're pregnant, have an abscess, or your symptoms don't go away, you may need to have surgery or be hospitalized for treatment.

Treatment cannot fix any permanent damage already done to your internal organs.

If you don't get treated, complications can occur, such as:

• Scar tissue may develop in your fallopian tubes.
• Infertility.
• An abscess may develop in your reproductive organs. If untreated, this could become a life-threatening infection.
• Long-term pelvic or abdominal (belly) pain.

Can pelvic inflammatory disease be prevented?

The best way to protect yourself against STIs is not to have sex.

If you do decide to have sex, a few ways you can lower your risk include to:

• Practice safe sex by using a condom every time you have sex, limit your number of sex partners, and ask your partners about their sexual history.
• Get tested for chlamydia and gonorrhea every year and ask your partner to get tested.
• Don't douche since this can upset the balance of bacteria in your vagina.
