The Centers for Disease Control and Prevention (CDC) will begin officially recognizing detransitioning—reversing gender transition procedures—in its ICD-10 diagnosis codes starting in October, a move that will affect insurance billing and medical data collection nationwide.
The update marks a significant shift in how the U.S. medical system tracks and treats individuals seeking to reverse prior gender transition interventions. Advocates argue this change will address longstanding gaps in care and documentation for those who detransition.
Until now, detransitioners—those who desist from gender dysphoria or seek to reverse sex-reassignment procedures—have lacked specific diagnostic codes. This absence has made it difficult for them to access appropriate care or for researchers to track outcomes, according to commentary from Do No Harm and reporting in publications such as The Federalist and The Hill. Without a dedicated code, insurance coverage for detransition-related care has often been inconsistent, and the medical system has struggled to collect reliable data on this population.
New ICD-10 Codes and Their Impact
The CDC’s update will add several new codes to the ICD-10 system, including F64.A, "Gender Identity Disorder, in remission." This code applies to patients who no longer meet criteria for gender dysphoria. Additional codes under the "Personal History of Sex Reassignment" category will specify whether a patient has a history of social, medical, or surgical gender transition. Another new code, Z87.893, will denote "Personal history of gender de transition," according to CMS documentation and Do No Harm.
Kurt Miceli, MD, chief medical officer at Do No Harm, said the new codes "will significantly enhance and refine patient care to ensure those desisting from gender dysphoria are properly recognized."
"Giving detransitioners visibility in the medical system will help them get the medical attention they need and open the door for proper coverage and real-world research into the impact of sex-rejecting interventions."

The codes are intended to improve recordkeeping, facilitate insurance coverage for related treatments, and enable more robust research into the outcomes of gender transition and detransition, according to Do No Harm and The Hill. By providing a standardized way to document detransition, the medical community will be better equipped to study the long-term effects of gender transition procedures and their reversals. This could also help inform future clinical guidelines and policy decisions.
Previously, the lack of specific codes meant that detransitioners were often grouped with other patients or left out of official statistics. The new codes are expected to help clinicians more accurately document patient histories and tailor care to the needs of those who have undergone or reversed gender transition interventions.
Advocates and Criticism
Advocates for detransitioners have argued that the absence of diagnostic codes has contributed to what Do No Harm called an "official blindness to the very existence of detransitioners." Dr. Aida Cerundolo, a senior fellow at Do No Harm, wrote that the new codes will allow detransitioners to "be seen and counted" in the healthcare system.
The Federalist reported that the codes could also help quantify how many people regret gender transition interventions, a figure sought by critics of current gender medicine practices. The article cited Do No Harm’s estimate that "well over 14,000 children have received sex-change treatments in recent years," with some expected to seek reversal as they age.
Supporters of gender transition procedures have not publicly responded to the CDC’s coding update, and the CDC has not issued a statement addressing criticism of gender medicine practices. The addition of detransition codes comes amid ongoing debate over the safety, efficacy, and oversight of gender transition treatments, particularly for minors.
Some medical professionals and advocacy groups have called for more comprehensive data on both transition and detransition outcomes. They argue that improved documentation will help ensure that all patients receive appropriate care, regardless of the direction of their gender-related medical decisions.
Policy and Political Context
The CDC’s decision follows calls from some political leaders for greater oversight of gender transition procedures. Last week, Vice President J.D. Vance called for criminal penalties for medical professionals who misuse billing codes to obtain insurance coverage for gender transition surgeries on minors, according to The Federalist.
The new codes were developed with input from Do No Harm, a medical watchdog group critical of current gender medicine practices. The group and its allies argue that the codes will help document the harms of transgender procedures and provide a pathway for recovery for those seeking to detransition.
The CDC’s update is scheduled to take effect October 1, according to Icd 10 Codes — cms.gov. Medical providers, insurers, and researchers will begin using the new codes at that time, which could lead to changes in how detransition-related care is delivered and reimbursed.
The addition of detransition codes to the ICD-10 system represents a notable development in the ongoing discussion over gender medicine in the United States. As the new codes are implemented, their impact on patient care, insurance coverage, and medical research will be closely watched by both advocates and critics.
