ICD-10 Codes for Erectile Dysfunction Simplified - A Guide for Urologists

Erectile dysfunction is one of the most common and sensitive conditions that urologists encounter, impacting millions of men globally. Despite its prevalence, coding for erectile dysfunction in ICD-10 often presents a unique challenge, as each code captures specific nuances of the condition. A slight misstep in coding can lead not only to claim denials but also to lapses in medical records, affecting patient care and continuity.

This guide aims to simplify ICD-10 codes for erectile dysfunction, offering urologists a clear roadmap for coding accuracy. Let’s explore the essentials, decode the most relevant codes, and discuss best practices that can streamline your workflow and reinforce the quality of patient care.

What ICD-10 Code Should You Use for Erectile Dysfunction?

When coding for erectile dysfunction in male patients, ICD-10 provides several specific codes under the N52 category. Each code within this category helps to pinpoint the underlying cause, making it essential to choose the most appropriate one based on the patient’s diagnosis.

Let’s Breakdown the N52 Category 

N52.0 - Vasculogenic Erectile Dysfunction

The ICD-10 code N52.0 is designated for vasculogenic erectile dysfunction, which is erectile dysfunction primarily caused by vascular or blood flow issues. Vasculogenic erectile dysfunction is often linked to underlying vascular conditions, such as hypertension, diabetes, atherosclerosis, or other cardiovascular disorders. These conditions impede blood flow to the penile tissue, resulting in difficulties achieving or maintaining an erection.

Proper coding for vasculogenic erectile dysfunction not only ensures accurate reimbursement but also captures the patient's cardiovascular health status, which can be critical for long-term care planning.

Key Sub-Categories Under N52.0

ICD-10 further breaks down N52.0 to specify the exact nature of the vasculogenic cause. Here’s a look at the main sub-categories:

• N52.01 - Erectile Dysfunction Due to Arterial Insufficiency

This code applies when erectile dysfunction is caused by arterial insufficiency, where restricted blood flow through the arteries impairs erectile function. This is common in patients with atherosclerosis or peripheral artery disease.

Proper documentation should include any findings on arterial insufficiency or related vascular diseases to support this coding choice.

• N52.02 - Corporo-venous occlusive erectile dysfunction

This sub-category is used when the issue is primarily venous, such as with a venous leak. In these cases, blood flow to the penis may be adequate, but it leaks out prematurely through the veins, preventing the maintenance of an erection.

Supporting documentation for this code would typically involve diagnostic findings that indicate venous insufficiency or venous leaks.

• N52.03 - Combined arterial insufficiency and corporo-venous occlusive erectile dysfunction

Use this code when erectile dysfunction results from a combination of both arterial insufficiency and venous leak. This is often seen in complex cases where multiple vascular impairments coexist.

For this code, documentation should clearly show findings related to both arterial and venous issues.

Documentation Tips for N52.0 Coding

Accurate documentation is crucial for N52.0 codes to avoid claim denials and ensure a clear understanding of the patient’s condition:

Record Specific Vascular Diagnoses: Clearly document whether the patient has an arterial or venous condition (or both) causing the erectile dysfunction.

Include Test Results: Provide details from any diagnostic imaging, blood flow studies, or assessments that confirm the presence of vascular issues.

Mention Contributing Factors: If applicable, note any underlying conditions (e.g., diabetes, hypertension) that contribute to vasculogenic erectile dysfunction. This can help clarify the primary cause and support coding.

N52.1 - Erectile Dysfunction Due to Diseases Classified Elsewhere

The ICD-10 code N52.1 is used when erectile dysfunction arises as a direct result of other underlying health conditions classified elsewhere in the ICD-10 system, particularly diseases affecting the endocrine, metabolic, or systemic health of the patient. 

Common Conditions Linked to N52.1

Erectile dysfunction coded under N52.1 is typically associated with certain conditions that directly affect hormonal balance, nerve function, or other bodily systems. Key examples include:

• Diabetes Mellitus: A common cause of secondary erectile dysfunction, diabetes can lead to neuropathy (nerve damage) and impaired blood flow, both of which contribute to erectile difficulties. In this case, E10–E14 codes for erectile dysfunction due to diabetes mellitus would be noted in conjunction with N52.1.

• Hypogonadism: A condition characterized by low testosterone levels, often associated with erectile dysfunction. In such cases, the endocrine dysfunction can be coded alongside E29.1 (Testicular Hypofunction) to fully capture the relationship.

• Thyroid Disorders: Both hyperthyroidism and hypothyroidism can affect erectile function. Use relevant codes (e.g., E03 for Hypothyroidism or E05 for Hyperthyroidism) in combination with N52.1 to detail the connection.

• Chronic Kidney Disease (CKD): Advanced CKD can lead to hormonal imbalances and blood flow issues, contributing to erectile dysfunction. In these cases, CKD should be coded alongside N52.1.

N52.2 - Drug-Induced Erectile Dysfunction

The ICD-10 code N52.2 is used to document erectile dysfunction that occurs as a side effect of medication. Drug-induced erectile dysfunction is a condition where prescribed or over-the-counter medications interfere with sexual function, leading to difficulties in achieving or maintaining an erection.

Pair N52.2 with the relevant codes that describe the drug or chemical substance, often found in the T36–T50 range in ICD-10, which allows for specificity on the exact medication causing the dysfunction.

 If necessary, an adverse effect code may be applied to indicate that the erectile dysfunction is an unintended side effect of prescribed treatment.

Example Code Combination

For a patient experiencing erectile dysfunction due to beta-blockers prescribed for hypertension:

• N52.2 - Drug-Induced Erectile Dysfunction

• I10 - Essential (primary) Hypertension

• T44.5X5A - Adverse effect of beta-blockers, initial encounter

N52.3 - Postprocedural Erectile Dysfunction

The ICD-10 code N52.3 is used to document erectile dysfunction that occurs as a direct result of a medical procedure or surgical intervention. 

N52.31 - Erectile Dysfunction Following Radical Prostatectomy

This code applies when erectile dysfunction occurs as a result of a radical prostatectomy, which involves the surgical removal of the prostate gland, often to treat prostate cancer. The procedure can disrupt the nerves and blood vessels that control erectile function.

Documentation Tips: Include specifics of the prostatectomy procedure and any postoperative assessments or diagnostics showing nerve damage or other physical changes affecting erectile function.

N52.32 - Erectile Dysfunction Following Radical Cystectomy

Use this code when erectile dysfunction follows a radical cystectomy (complete removal of the bladder). This procedure often affects surrounding tissues, blood vessels, and nerves that play a role in erectile function.

Documentation Tips: Clearly note that the cystectomy was performed and any relevant postoperative findings indicating the onset of erectile dysfunction, such as vascular or nerve assessments.

N52.33 - Erectile Dysfunction Following Urethral Surgery

This code is used when erectile dysfunction occurs as a result of urethral surgery, which may involve repairs or reconstructions due to injury, scarring, or disease. Such surgeries can impact erectile function if the nerves or blood supply are disrupted.

Documentation Tips: Describe the urethral procedure performed and any diagnostic tests linking it to the erectile dysfunction, such as blood flow studies or nerve conduction tests.

N52.34 - Erectile Dysfunction Following Simple Prostatectomy

Simple prostatectomy refers to the removal of part or all of the prostate gland without the radical approach typically used for cancer. This procedure is often used for benign prostate enlargement but can still impact erectile function.

Documentation Tips: Record details of the simple prostatectomy procedure and any evidence of nerve or vascular impairment that aligns with erectile dysfunction.

N52.35 - Erectile Dysfunction Following Radiation Therapy

This code is appropriate when erectile dysfunction results from radiation therapy used to treat cancers in or near the pelvic area, including prostate cancer. Radiation can damage tissues, nerves, and blood vessels essential for erectile function.

Documentation Tips: Document the type and dosage of radiation therapy received and any findings that confirm tissue or nerve damage related to erectile dysfunction.

N52.36 - Erectile Dysfunction Following Interstitial Seed Therapy

Also known as brachytherapy, interstitial seed therapy involves implanting radioactive seeds in the prostate to treat cancer. The radiation from the seeds can affect erectile function by damaging local tissues and nerves.

Documentation Tips: Include specifics about the seed therapy, including number of seeds implanted and their location, along with postoperative findings that connect the therapy to erectile dysfunction.

N52.37 - Erectile Dysfunction Following Prostate Ablative Therapy

Prostate ablative therapy, such as cryotherapy or high-intensity focused ultrasound (HIFU), is used to destroy cancerous prostate tissue. The procedure can lead to erectile dysfunction if it disrupts nearby nerves or blood flow.

Documentation Tips: Provide details about the ablative therapy used, as well as any subsequent assessments showing damage to nerves or blood vessels essential for erectile function.

N52.39 - Other and Unspecified Postprocedural Erectile Dysfunction

This code is used when erectile dysfunction occurs after procedures that don’t fit into the specific categories above. It could include rare or complex procedures affecting the pelvic area that lead to erectile issues.

Documentation Tips: Clearly outline the procedure performed, any complications or side effects observed, and how these link to the erectile dysfunction.

N52.9 - Male Erectile Dysfunction, Unspecified

The ICD-10 code N52.9 is used to document cases of male erectile dysfunction when the specific cause is not identified or documented in the patient's records. 

This code is a general, non-specific option and serves as a catch-all category when the underlying etiology of the erectile dysfunction is unclear or unspecified.

N52.9 should be used sparingly, as it lacks the detail needed for precise clinical insight or billing accuracy. Whenever possible, more specific codes within the N52 category should be chosen to reflect the cause of erectile dysfunction, such as vasculogenic, drug-induced, postprocedural, or due to diseases classified elsewhere.
