Medical Billing and Coding Guide for Substance Abuse: All You Need to Know December 1, 2021

In simple terms, substance abuse refers to the pattern of harmful use of any substance to change one’s mood.  Furthermore, the term “substances” can encompass not only alcohol and drugs ( legal or illegal) but also substances that do not technically qualify as drugs. On the other hand, “abuse” involves using a substance in a way that is not intended or recommended or when you consume too much of it. 

The substance abuse medical billing process is only one element of revenue cycle management, which begins with gathering accurate patient information. In this guide, we’ll guide you all you need to know about the Medical Billing and Coding Guide for Substance Abuse.

Substance Abuse Diagnosis

Psychiatrists, psychologists, and licensed drug counselors are often involved in the evaluation process for diagnosing alcoholism, drug addiction, or other substance use disorders. Testing blood, urine, or other tests can assess drug use but not a diagnostic test for addiction. These tests can help monitor recovery as well as treatment.

Mental health professionals diagnose substance abuse using criteria from the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published by the American Psychiatric Association.

How to identify correct substance abuse ICD-10-CM codes?

ICD-10-CM uses the format F1x.xxx for substance use codes. In ICD-10-CM, the letter F indicates that the code belongs to Chapter 5: Mental, Behavioral, and Neurodevelopmental Disorders. Furthermore, the number 1 represents a mental or behavioral disorder due to the use of psychoactive substances. The first x, the next digit, indicates the problematic substance (see table below in Step 1). After the decimal point, all numbers indicate the severity and nature of the problem (see Table in Step 2 below). For example,  F10.121 refers to alcohol abuse with intoxication delirium. Not all specifiers are used for every substance (primarily perceptual disturbance), so users should refer to the complete ICD-10-CM code set.
