2025 ICD-10-CM Diagnosis Code O85

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. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

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.

Convert O85 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.

Patient Education

Infections and Pregnancy

During pregnancy, some common infections like the common cold or a skin infection do not usually cause serious problems. But other infections can be dangerous to you, your baby, or both. Some infections may lead to preterm birth and low birth weight babies. Others can cause serious illness, birth defects, and lifelong disabilities, such as hearing loss or learning problems.

Some of the infections that can be dangerous during pregnancy include:

• Bacterial vaginosis (BV)
• Group B strep (GBS)
• Hepatitis
• Sexually transmitted infections (STIs)
• Toxoplasmosis
• Urinary tract infections
• Yeast infections
• Zika virus

To try to prevent infections:

• Don't eat raw or undercooked meat.
• Don't share food or drinks with other people.
• Wash your hands frequently.
• Don't empty cat litter. Cats can transmit toxoplasmosis.
• Talk to your health care provider about vaccinations.
• If you have sex during pregnancy, use a condom every time.

If you do get an infection during pregnancy, contact your health care provider about how best to protect you and your baby. Only some medicines are safe during pregnancy.

Postpartum Care

Taking home a new baby is one of the happiest times in a woman's life. But it also presents both physical and emotional challenges. :

• Get as much rest as possible. You may find that all you can do is eat, sleep, and care for your baby. And that is perfectly okay. You will have spotting or bleeding, like a menstrual period, off and on for up to six weeks.
• You might also have swelling in your legs and feet, feel constipated, have menstrual-like cramping. Even if you are not breastfeeding, you can have milk leaking from your nipples, and your breasts might feel full, tender, or uncomfortable.
• Follow your doctor's instructions on how much activity, like climbing stairs or walking, you can do for the next few weeks.
• Doctors usually recommend that you abstain from sexual intercourse for four to six weeks after birth.

In addition to physical changes, you may feel sad or have the "baby blues." If you are extremely sad or are unable to care for yourself or your baby, you might have a serious condition called postpartum depression.

Sepsis

What is sepsis?

Sepsis is your body's overactive and extreme response to an infection. Sepsis is a life-threatening medical emergency. Without quick treatment, it can lead to tissue damage, organ failure, and even death.

What causes sepsis?

Sepsis happens when an infection you already have triggers a chain reaction throughout your body. Bacterial infections are the most common cause, but other types of infections can also cause it.

The infections are often in the lungs, stomach, kidneys, or bladder. It's possible for sepsis to begin with a small cut that gets infected or with an infection that develops after surgery. Sometimes, sepsis can occur in people who didn't even know that they had an infection.

Who is more likely to develop sepsis?

Anyone with an infection could get sepsis. But certain people are more likely to develop it:

• Adults 65 or older
• People with chronic (long-lasting) conditions, such as diabetes, lung disease, cancer, and kidney disease
• People with weakened immune systems
• Pregnant women
• Children younger than one

What are the symptoms of sepsis?

Sepsis can cause one or more of these symptoms:

• Rapid breathing and heart rate
• Shortness of breath
• Confusion or disorientation
• Extreme pain or discomfort
• Fever, shivering, or feeling very cold
• Clammy or sweaty skin

It's important to get medical care right away if you think you might have sepsis or if your infection is not getting better or is getting worse.

What other problems can sepsis cause?

Severe cases of sepsis can lead to septic shock, where your blood pressure drops to a dangerous level and multiple organs can fail.

How is sepsis diagnosed?

To find out if you have sepsis, your health care provider:

• Will take your medical history, which includes asking about your symptoms
• Will do a physical exam, which includes checking vital signs (your temperature, blood pressure, heart rate, and breathing)
• Will likely order lab tests that check for signs of infection or organ damage
• May order imaging tests such as an x-ray or a CT scan to find the location of the infection

Many of the signs and symptoms of sepsis can also be caused by other medical conditions. This may make sepsis hard to diagnose in its early stages.

What are the treatments for sepsis?

It is very important to get treatment right away. Treatment usually includes:

• Antibiotics.
• Maintaining blood flow to organs. This may involve getting oxygen and intravenous (IV) fluids.
• Treating the source of the infection.
• If needed, medicines to increase blood pressure.

In serious cases, you might need kidney dialysis or a breathing tube. Some people need surgery to remove tissue damaged by the infection.

Can sepsis be prevented?

To prevent sepsis, you should try to prevent getting an infection:

• Take good care of any chronic health conditions that you have
• Get recommended vaccines
• Practice good hygiene, such as handwashing
• Keep cuts clean and covered until healed
