What is the ICD-10 (International Classification of Diseases, 10th Revision) diagnosis code for a patient being tested for a Sexually Transmitted Disease (STD) after reported exposure?

From the Guidelines

The ICD-10 diagnosis code for a patient being tested for a Sexually Transmitted Disease (STD) after reported exposure is Z20.2, which specifically represents "Contact with and (suspected) exposure to infections with a predominantly sexual mode of transmission". This code is used when a patient presents for STD testing following a known or suspected exposure but has not yet been diagnosed with an infection. The Z20.2 code falls under the broader category of Z codes, which are used to represent factors influencing health status and contact with health services rather than actual diseases or conditions. When documenting this encounter, it's essential to note that once a positive diagnosis is established, the appropriate code for the specific STD would replace this exposure code, as recommended by various health organizations, including the CDC 1. Key points to consider when using this code include:

• The patient has reported exposure to an STD
• The patient has not yet been diagnosed with an infection
• The code is used for billing and medical documentation purposes
• The code may be replaced by a specific STD code if a diagnosis is established It's crucial to follow the guidelines set by reputable health organizations, such as the CDC, to ensure accurate documentation and billing for STD testing and treatment, as outlined in studies such as 1.

From the Research

ICD-10 Diagnosis for Testing for STD after Reported Exposure

• The ICD-10 diagnosis code for a patient being tested for a Sexually Transmitted Disease (STD) after reported exposure is not explicitly stated in the provided studies 2, 3, 4, 5, 6.
• However, the studies provide information on the diagnosis and treatment of STDs, as well as the use of ICD-10 codes for surveillance and reporting purposes.
• For example, study 5 discusses the quality of diagnosis and procedure coding in ICD-10 administrative data, while study 6 evaluates the sensitivity and specificity of ICD-10-CM codes for identifying substance-exposed newborns and neonatal abstinence syndrome.

Relevant ICD-10 Codes

• The studies mention the following ICD-10 codes:
  • F11.20: Maternal dependence on opioids
  • F13.20: Maternal dependence on benzodiazepines
  • P04.49: Newborn affected by maternal use of drugs of addiction
  • P96.1: Withdrawal symptoms from maternal drugs of addiction
• However, these codes are not specifically related to testing for STDs after reported exposure.

Limitations

• The provided studies do not directly address the question of ICD-10 diagnosis codes for testing for STDs after reported exposure.
• Further research or consultation with a medical professional may be necessary to determine the appropriate ICD-10 code for this specific scenario 2, 3, 4, 5, 6.
