Free Viability Check →VA raters deny secondary SUD claims more often for missing or incomplete records than for weak nexus letters. Before you commission a physician nexus opinion, read this. The records you gather, or fail to gather, determine whether the nexus author can write a specific, record-supported opinion or a generic one that won't survive scrutiny. This article is a prerequisite step, not an afterthought.
For most VA claims, clinical records serve primarily to document the diagnosis and severity of a condition. In SUD secondary claims, treatment records serve an additional function: they establish the factual timeline of the substance use and its relationship to the primary condition.
The nexus opinion author needs records to review. The VA rater uses records to evaluate the nexus opinion's basis. The C&P examiner draws on records when generating their own opinion. Records are not supporting documents in SUD claims. They are the foundation everything else is built on.
The claim requires a formal DSM-5 diagnosis of the relevant SUD (alcohol use disorder, opioid use disorder, sedative use disorder, etc.). This diagnosis should appear in:
Informal documentation ("patient drinks frequently," "patient has history of alcohol use") is not sufficient. The diagnosis must be explicit and coded using DSM-5 criteria.
The AUDIT (Alcohol Use Disorders Identification Test) and AUDIT-C are standardized screening tools used in VA primary care. Scores and responses are often in VA treatment records and provide objective quantification of alcohol use severity. AUDIT scores of 8+ (men) or 7+ (women) indicate hazardous use; higher scores indicate harmful use or dependence.
These screenings are part of standard VA primary care and should appear in every veteran's VA record if they reported alcohol use during wellness visits. Pulling all available AUDIT results across time shows a timeline of reported use severity.
If the veteran has undergone alcohol or drug detox or residential rehabilitation, those records are particularly valuable. They typically document:
Records showing the severity and treatment of the primary service-connected condition (PTSD, chronic pain, etc.) are essential for the timeline argument. Look for:
When treatment records from the primary condition already document the relationship between the primary symptoms and substance use, the nexus opinion has direct record support.
For opioid use disorder secondary to prescribed pain treatment, pharmacy records are essential. These include:
The prescribing record tells the story of iatrogenic dependence in objective terms: the veteran was prescribed an opioid in 2010 for a service-connected condition, the dose increased in 2012, a higher potency formulation was prescribed in 2014, and OUD was diagnosed in 2016. That timeline is your causal chain.
Request VA medical records through:
Allow six to eight weeks for a complete records request.
Private substance use treatment providers (residential programs, outpatient addiction clinics, detox centers) maintain separate records. Request these directly from each provider. Medical records authorization forms are required.
The National Personnel Records Center (NPRC) in St. Louis maintains service records and service medical records. Request via eVetRecs at the National Archives website.
When requesting a physician nexus opinion, organize the records chronologically and flag the most relevant sections. The nexus author needs to review actual records, not a summary. Well-organized records allow the author to produce a more thorough and specific opinion.
