Cocaine Abuse ICD-10 Codes and Substance Abuse History Coding Guide

Accurate coding starts with knowing the right cocaine abuse ICD 10 designation. The ICD 10 code for polysubstance abuse applies when multiple substances are involved simultaneously, and choosing incorrectly affects billing and treatment records. The ICD 10 code for history of alcohol abuse covers patients in remission or with documented past dependence. History of substance abuse documentation matters for continuity of care, insurance reimbursement, and risk stratification. The ICD 10 code for history of substance abuse differs from active use codes and carries its own clinical and administrative implications.

We walk through these codes clearly so clinicians, coders, and administrators select the right designation every time.

Cocaine Abuse ICD-10 and Active Use Codes

Cocaine abuse ICD 10 falls under the F14 category. The primary codes include: F14.10 (cocaine abuse, uncomplicated), F14.120 (cocaine abuse with intoxication, uncomplicated), and F14.20 (cocaine dependence, uncomplicated). Selecting between abuse and dependence requires clinical documentation of behavioral patterns and DSM-5 criteria.

The ICD 10 code for polysubstance abuse uses F19 codes — “other psychoactive substance” — when no single substance dominates the clinical picture. F19.10 covers polysubstance abuse uncomplicated. Specificity matters: payors and quality reporting programs may require substance-specific codes when the record supports them.

Distinguishing Abuse from Dependence

ICD-10-CM distinguishes cocaine abuse (harmful use pattern) from cocaine dependence (physiological tolerance, withdrawal). History of substance abuse coding uses Z codes when the condition is in full remission and no longer the focus of care. Clinicians should document remission status explicitly to support Z code use.

History Codes for Alcohol and Substance Abuse

The ICD 10 code for history of alcohol abuse is Z87.891 — personal history of alcoholism. This Z code applies when alcohol use disorder is fully resolved and no longer active. The ICD 10 code for history of substance abuse more broadly is Z87.898 — personal history of other psychoactive substance abuse.

History of substance abuse documentation in the medical record must clearly indicate that the condition is resolved. Vague or incomplete documentation causes coders to default to active-use codes, which misrepresents the patient’s current clinical status and can affect insurance coverage and treatment eligibility.

Coding Best Practices

When the ICD 10 code for history of substance abuse appears on a claim, payers expect documentation of the resolution date and current monitoring status. Cocaine abuse ICD 10 codes require specificity around complications — withdrawal, intoxication, and associated disorders each have distinct codes. A clinical documentation improvement (CDI) program helps ensure coders have the records they need.

Always query the provider when documentation is ambiguous. History of substance abuse vs. active disorder is a significant clinical and billing distinction that affects everything from medication authorization to mental health carve-out billing.

Key takeaways: Cocaine abuse ICD 10 coding requires distinguishing abuse from dependence, active use from history. The ICD 10 code for polysubstance abuse uses F19 when no single substance dominates. Use Z87 codes when history of substance abuse is documented as resolved to accurately represent patient status.
