What DC 7629 Covers
Diagnostic Code 7629 in 38 CFR 4.116 is the VA's rating code for endometriosis. It is one of a small number of dedicated gynecological codes in the rating schedule and is used to capture the functional disability produced by endometriosis as a chronic condition rather than by any single component (pain alone, bleeding alone, or surgical history alone).
Endometriosis affects approximately 10 percent of reproductive-age women in the general population and is increasingly recognized among women veterans, who face the same anatomic risk plus additional service-related contributors including pelvic trauma, repeated heavy load-bearing, deployment-related disruption to menstrual hygiene and gynecologic care, and Gulf War-era exposures that have been epidemiologically linked to a higher prevalence of endometriosis.
Endometriosis: The Underlying Disease
Endometriosis is defined by the presence of endometrial-like tissue (glands and stroma) outside the uterine cavity. The ectopic tissue responds to the cyclical hormonal signals of the menstrual cycle, producing local inflammation, fibrosis, adhesion formation, and pain. The condition is estrogen-dependent and is broadly characterized as a chronic inflammatory disease.
Anatomic Phenotypes
Three principal phenotypes are recognized clinically:
- Superficial peritoneal endometriosis: small implants on the peritoneum, ovaries, or uterosacral ligaments
- Ovarian endometrioma: cystic involvement of the ovary, often described on imaging as a "chocolate cyst" because of the dark hemosiderin-laden fluid
- Deep infiltrating endometriosis: lesions penetrating 5 mm or more beneath the peritoneum, commonly involving the rectovaginal septum, bowel wall, ureter, bladder, or uterosacral ligaments
Symptom Spectrum
The classic symptom triad is cyclical pelvic pain (worse around menstruation), dysmenorrhea (painful menstrual cramping), and dyspareunia (pain with intercourse). Additional symptoms vary by anatomic involvement: dyschezia and hematochezia with bowel involvement; dysuria and hematuria with bladder involvement; flank pain with ureteric involvement; chest or shoulder pain with diaphragmatic involvement; infertility (present in 30 to 50 percent of women with endometriosis); and chronic fatigue.
Diagnostic Standard
The historical gold standard was laparoscopic visualization with histologic confirmation. Modern practice increasingly accepts a clinical diagnosis with supporting imaging (transvaginal ultrasound, MRI showing endometriomas or deep infiltrating disease) when the clinical picture is consistent. For VA rating purposes, definitive confirmation by laparoscopy is most commonly the basis for the diagnosis in the file.
Service-Related Mechanisms
Risk factors with potential service relevance include early menarche, short menstrual cycles, heavy menstrual flow, retrograde menstruation potentially exacerbated by heavy load-bearing and prolonged supine positioning, pelvic trauma, and environmental exposures including dioxin and PCB compounds linked epidemiologically to higher endometriosis prevalence.
The Rating Tiers in Detail
DC 7629 has three tiers calibrated to treatment response and anatomic involvement.
10 Percent
Pelvic pain or heavy or irregular bleeding requiring continuous treatment for control. The "continuous treatment" component captures veterans on ongoing hormonal therapy (combined oral contraceptives, progestin-only therapy, levonorgestrel intrauterine device) or chronic NSAID regimens to maintain control of symptoms.
30 Percent
Pelvic pain or heavy or irregular bleeding not controlled by treatment. This tier captures veterans whose symptoms persist despite ongoing hormonal or analgesic treatment, often requiring escalation to GnRH agonists (leuprolide), GnRH antagonists (elagolix), or repeated surgical intervention.
50 Percent
Lesions involving the bowel or bladder confirmed by laparoscopy, with pelvic pain or heavy or irregular bleeding, and bowel or bladder symptoms. This tier requires the combination of all three elements: anatomic confirmation of bowel/bladder involvement, persistent pain/bleeding, and corresponding bowel or bladder symptoms (dyschezia, hematochezia, dysuria, hematuria, urinary frequency).
Extraschedular Consideration
Veterans with severe disease producing marked functional impairment beyond what the schedular tiers capture (frequent hospitalizations, marked occupational impact, multiple surgical interventions including hysterectomy and oophorectomy in young women) may be considered for extraschedular review under 38 CFR 3.321(b)(1).
Hysterectomy and Oophorectomy Ratings
When endometriosis treatment requires hysterectomy or bilateral oophorectomy, additional ratings under DC 7617 (uterus, removal of) or DC 7619 (ovary, removal of) may apply. The convalescent rating period under 38 CFR 4.30 covers the immediate post-operative period.
Service Connection Pathways
Several pathways are available for endometriosis claims.
Direct Service Connection
When service treatment records document recurrent severe dysmenorrhea, chronic pelvic pain, dyspareunia, or other endometriosis-consistent symptoms during service, and the post-service course leads to a definitive diagnosis, direct service connection is the most straightforward pathway. The medical opinion connects the documented in-service symptom pattern to the eventual diagnosis.
The diagnostic delay between symptom onset and definitive diagnosis (commonly years) is well documented in the medical literature, and rating decisions should not penalize a veteran for the absence of an in-service definitive diagnosis when the in-service symptom pattern is consistent.
Secondary Service Connection Under 38 CFR 3.310
Endometriosis can be secondary to:
- Service-connected pelvic trauma producing retrograde menstrual flow and ectopic implantation
- Service-connected immune or inflammatory disease (the relationship between endometriosis and systemic inflammation is increasingly recognized)
- Aggravation by service-connected conditions producing chronic pain and reduced ambulation (rare but plausible in specific cases)
Aggravation Theory
When endometriosis predated military service or arose from another cause, the aggravation pathway requires the opinion to identify baseline-to-current change attributable to service or a service-connected condition.
Gulf War and Multisymptom Pathways
38 CFR 3.317 provides for presumptive service connection of certain medically unexplained chronic multisymptom illnesses for qualifying Gulf War veterans. Several epidemiologic studies have documented an elevated prevalence of endometriosis among women veterans who served in the Persian Gulf, Iraq, or Afghanistan theaters. When the clinical presentation includes chronic pelvic pain with associated multisystem features that cannot be otherwise explained, the presumptive pathway may be argued in the alternative to direct or secondary theories.
The presumptive framework does not require a nexus opinion, only a qualifying period of service, a current diagnosis manifesting to a degree of 10 percent or more, and the absence of an alternative explanation.
Evidence That Supports the Rating
The records most useful for a defensible DC 7629 rating include the following.
Gynecology Evaluation
Specialist evaluation with the diagnosis, the staging when available (the rASRM staging from minimal to severe), the anatomic distribution of lesions, and the treatment plan.
Laparoscopic or Imaging Confirmation
Operative report from any prior laparoscopy with description of the findings and any biopsy or excision pathology. When laparoscopy has not been performed, transvaginal ultrasound or pelvic MRI reports identifying endometriomas, deep infiltrating disease, or characteristic imaging features.
Pain and Bleeding Diary
A patient-maintained diary documenting cyclical pain patterns, bleeding heaviness and irregularity, breakthrough symptoms despite treatment, and functional impact (missed work days, inability to perform physical activities, sleep disturbance from pain).
Treatment History
Detailed pharmacy records of NSAID prescriptions, combined oral contraceptive course (and reasons for any discontinuation), progestin-only therapy, GnRH agonist or antagonist therapy (typical course 6 months due to bone mineral density concerns), levonorgestrel intrauterine device placement, and any surgical interventions (excisional or ablative laparoscopy, hysterectomy, oophorectomy).
Functional Impact Documentation
Statements describing missed work days, occupational accommodations required, inability to engage in physical activities during flares, sleep disturbance, and impact on relationships and quality of life.
Mental Health Component
Many women with chronic endometriosis develop secondary depression or anxiety from the chronic pain and quality-of-life impact. When documented, this can support a separate mental health rating under DC 9434 or 9400, with a secondary nexus opinion linking the mental health condition to the endometriosis under 38 CFR 3.310.
Common Pitfalls
Several recurring issues weaken endometriosis claims.
Missing In-Service Symptom Documentation
The diagnostic delay between symptom onset and definitive diagnosis often means that service treatment records document only the precursor symptoms. The medical opinion must explicitly bridge the in-service symptom pattern to the eventual diagnosis using the well-documented diagnostic-delay literature.
Treating Each Symptom Separately
Veterans sometimes claim pelvic pain, dysmenorrhea, and dyspareunia as separate conditions rather than as manifestations of the unifying endometriosis diagnosis. The unified DC 7629 rating typically captures the disability more completely; pyramiding under 38 CFR 4.14 prohibits double-rating manifestations of the same disease.
Failure to Address Bowel/Bladder Involvement
The 50 percent tier requires three specific elements: laparoscopic confirmation of bowel/bladder involvement, persistent pain/bleeding, and corresponding bowel/bladder symptoms. Records that document one or two of these without all three default to the 30 percent tier even when overall severity is high.
Missing Treatment-Response Documentation
The 10 versus 30 percent distinction turns on whether treatment controls symptoms. Records that describe ongoing treatment without specifying whether symptoms are controlled may default to the lower tier.
Missing Mental Health Secondary
When chronic pain has produced documented depression or anxiety, the secondary mental health rating is frequently missed and can substantially increase the combined disability.
Frequently Asked Questions
Diagnostic Code 7629 in 38 CFR 4.116 is the VA's rating code for endometriosis. It is rated 10, 30, or 50 percent based on the persistence of pelvic pain and irregular bleeding, the response to treatment, and the presence of bowel or bladder involvement requiring surgery. Endometriosis must be confirmed by laparoscopy or laparotomy or by imaging (transvaginal ultrasound, MRI) showing characteristic findings, plus a clinical course consistent with the diagnosis.
The schedule provides: 10 percent for pelvic pain or heavy or irregular bleeding requiring continuous treatment for control; 30 percent for pelvic pain or heavy or irregular bleeding not controlled by treatment; and 50 percent for lesions involving the bowel or bladder confirmed by laparoscopy, with pelvic pain or heavy or irregular bleeding, and bowel or bladder symptoms. Higher functional impact may support additional consideration under extraschedular review.
Yes. Direct service connection is available when service treatment records document pelvic pain, dysmenorrhea, or other symptoms consistent with endometriosis during service or within a year of separation, or when a medical opinion links current endometriosis to in-service factors. The Gulf War presumptive framework under 38 CFR 3.317 may apply to qualifying Gulf War veterans for medically unexplained chronic multisymptom illness presentations. Secondary service connection under 38 CFR 3.310 is available when endometriosis is caused by or aggravated by another service-connected condition, including service-connected immune or hormonal disorders and aggravation by service-connected pelvic trauma.
Strong records include a gynecology evaluation establishing the diagnosis (laparoscopic or imaging confirmation), pelvic ultrasound or MRI reports identifying endometriomas or deep infiltrating endometriosis, a pain diary documenting the cyclical pattern and impact on daily activities, treatment history (NSAIDs, hormonal therapy including combined oral contraceptives, progestins, GnRH agonists or antagonists, and surgical excision), pathology reports from any laparoscopic resection, and documentation of bowel or bladder involvement (deep infiltrating disease, dyschezia, dysuria, hematochezia, hematuria) when present.
