What each rating requires

The VA assigns the highest level your evidence actually supports. Read up the stack until your records stop matching.

  1. 50%

  2. 30%

    Thereafter, for five years, or to eleven years after date of inactivity

  3. 30%

    Following far advanced lesions diagnosed at any time while the disease process was active, minimum

  4. 20%

    Following moderately advanced lesions, provided there is continued disability, emphysema, dyspnea on exertion, impairment of health, etc

Notes on this code

These notes are part of the regulation. They change how the levels above are applied.

  • Note (1): The 100-percent rating under codes 6701 through 6724 is not subject to a requirement of precedent hospital treatment. It will be reduced to 50 percent for failure to submit to examination or to follow prescribed treatment upon report to that effect from the medical authorities. When a veteran is placed on the 100-percent rating for inactive tuberculosis, the medical authorities will be appropriately notified of the fact, and of the necessity, as given in footnote 1 to 38 U.S.C. 1156 (and formerly in 38 U.S.C. 356, which has been repealed by Public Law 90-493), to notify the Veterans Service Center in the event of failure to submit to examination or to follow treatment.
  • Note (2): The graduated 50-percent and 30-percent ratings and the permanent 30 percent and 20 percent ratings for inactive pulmonary tuberculosis are not to be combined with ratings for other respiratory disabilities. Following thoracoplasty the rating will be for removal of ribs combined with the rating for collapsed lung. Resection of the ribs incident to thoracoplasty will be rated as removal.

Inactive Pulmonary Tuberculosis (Moderately Advanced) — VA Diagnostic Code 6722

Understanding how the VA rates chronic, moderately advanced pulmonary tuberculosis once it has become inactive.


What This Condition Is

Diagnostic Code 6722 covers chronic, moderately advanced pulmonary tuberculosis that is now inactive. This falls under the Respiratory System in the VA rating schedule (38 CFR § 4.97) and is evaluated using the General Rating Formula for Inactive Pulmonary Tuberculosis.

Because the disease is classified as inactive, the VA's ratings reflect the period of time that has passed since the date of inactivity, as well as any continued disability that remains after the active disease process has ended.


Available Rating Levels

The VA assigns a rating based on how much time has passed since the date of inactivity and the severity of the lesions and remaining disability:

RatingWhat It Reflects
50%Thereafter for four years, or in any event, to six years after date of inactivity.
30%Thereafter, for five years, or to eleven years after date of inactivity.
30%Following far advanced lesions diagnosed at any time while the disease process was active — this is the minimum.
20%Following moderately advanced lesions, provided there is continued disability, emphysema, dyspnea on exertion, impairment of health, etc.
0%Otherwise.

What the VA Looks For

When rating inactive pulmonary tuberculosis under this code, the VA considers:

  • The date of inactivity and how many years have passed since that date, which drives the graduated ratings (50% and 30%).
  • The severity of lesions diagnosed while the disease was active — far advanced lesions carry a minimum 30% rating, while moderately advanced lesions may support a 20% rating.
  • Continued disability for the 20% level, such as emphysema, dyspnea on exertion (shortness of breath with activity), and impairment of health.

Important Notes

  • Note (1): The 100-percent rating under codes 6701 through 6724 is not subject to a requirement of precedent hospital treatment. It will be reduced to 50 percent for failure to submit to examination or to follow prescribed treatment upon report to that effect from the medical authorities. When a veteran is placed on the 100-percent rating for inactive tuberculosis, the medical authorities will be appropriately notified of the fact, and of the necessity — as given in footnote 1 to 38 U.S.C. 1156 (and formerly in 38 U.S.C. 356, which has been repealed by Public Law 90-493) — to notify the Veterans Service Center in the event of failure to submit to examination or to follow treatment.

  • Note (2): The graduated 50-percent and 30-percent ratings and the permanent 30 percent and 20 percent ratings for inactive pulmonary tuberculosis are not to be combined with ratings for other respiratory disabilities. Following thoracoplasty, the rating will be for removal of ribs combined with the rating for collapsed lung. Resection of the ribs incident to thoracoplasty will be rated as removal.

What next

How to claim this

Knowing the criteria is the first half. Getting your file to show them is the second.

  1. Find your level in the stack

    Read each rung against what your medical records already say. The level your records document today is the one the VA can support today.

  2. Name the gap

    Look at the rung above yours and write down exactly what it asks for that your file does not show yet — a diagnosis, a measurement, a prescribed brace, a doctor’s opinion linking it to service.

  3. Claim it by code

    File under diagnostic code 6722 and attach the evidence for the level you are asking for. Other Respiratory System codes may cover your secondary conditions.
