# diseases of the lungs and pleura---tuberculosis

Rating

> **Ratings for Pulmonary Tuberculosis Entitled on August 19, 1968**

**6701** Tuberculosis, pulmonary, chronic, far advanced, active 100

**6702** Tuberculosis, pulmonary, chronic, moderately advanced, active
100

**6703** Tuberculosis, pulmonary, chronic, minimal, active 100

unspecified 100

**6721** Tuberculosis, pulmonary, chronic, far advanced, inactive

**6722** Tuberculosis, pulmonary, chronic, moderately advanced, inactive

**6723** Tuberculosis, pulmonary, chronic, minimal, inactive

**6724** Tuberculosis, pulmonary, chronic, inactive, advancement
unspecified

General Rating Formula for Inactive Pulmonary Tuberculosis:

For two years after date of inactivity, following active tuberculosis,

which was clinically identified during service or subsequently 100

Thereafter for four years, or in any event, to six years after date

of inactivity 50

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, minimum 30

Following moderately advanced lesions, provided there is continued

disability, emphysema, dyspnea on exertion, impairment of

health, etc. 20

Otherwise 0

**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U.S.C. 1156 (and formerly in 38 U.S.C. 356, which has been repealed by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.

> **Ratings for Pulmonary Tuberculosis Initially Evaluated After August
> 19, 1968**

**6730** Tuberculosis, pulmonary, chronic, active 100

**Note**: Active pulmonary tuberculosis will be considered permanently
and totally disabling for non-service-connected pension purposes in the
following circumstances:

respiratory system.

\(b\) With severe associated symptoms or with extensive cavity
formation.

\(c\) Reactivated cases, generally.

\(d\) With advancement of lesions on successive examinations or while
under

treatment.

\(e\) Without retrogression of lesions or other evidence of material

improvement at the end of six months hospitalization or without

change of diagnosis from "active" at the end of 12 months
hospitalization.

Material improvement means lessening or absence of clinical symptoms,

and X-ray findings of a stationary or retrogressive lesion.

**6731** Tuberculosis, pulmonary, chronic, inactive:

Depending on the specific findings, rate residuals as interstitial lung

disease, restrictive lung disease, or, when obstructive lung disease is

the major residual, as chronic bronchitis (DC 6600). Rate thoracoplasty

as removal of ribs under DC 5297.

**Note**: A mandatory examination will be requested immediately
following notification that active tuberculosis evaluated under DC 6730
has become inactive. Any change in evaluation will be carried out under
the provisions of §3.105(e).

**6732** Pleurisy, tuberculous, active or inactive:

Rate under §§4.88c or 4.89, whichever is appropriate.

**Note**: Evaluate other residuals following pulmonary embolism under
the most appropriate diagnostic code, such as chronic bronchitis (DC
6600) or chronic pleural effusion or fibrosis (DC 6844), but do not
combine that evaluation with any of the above evaluations.

**6819** Neoplasms, malignant, any specified part of respiratory system
exclusive

of skin growths 100

**Note**: A rating of 100 percent shall continue beyond the cessation of
any surgical, X-ray, antineoplastic chemotherapy or other therapeutic
procedure. Six months after discontinuance of such treatment, the
appropriate disability rating shall be determined by mandatory VA
examination. Any change in evaluation based upon that or any subsequent
examination shall be subject to the provisions of §3.105(e) of this
chapter. If there has been no local recurrence or metastasis, rate on
residuals.

**6820** Neoplasms, benign, any specified part of respiratory system.
Evaluate using an

appropriate respiratory analogy.

> **Bacterial Infections of the Lung**

**6822** Actinomycosis.

**6823** Nocardiosis.

**6824** Chronic lung abscess.

General Rating Formula for Bacterial Infections of the Lung (diagnostic
codes

6822 through 6824):

Active infection with systemic symptoms such as fever, night sweats,

weight loss, or hemoptysis 100

Depending on the specific findings, rate residuals as interstitial lung

**6832** Pneumoconiosis (silicosis, anthracosis, etc.).

**6833** Asbestosis.

General Rating Formula for Interstitial Lung Disease (diagnostic

codes 6825 through 6833):

Forced Vital Capacity (FVC) less than 50-percent predicted,

or; Diffusion Capacity of the Lung for Carbon Monoxide by the

Single Breath Method (DLCO (SB)) less than 40-percent predicted,

or; maximum exercise capacity less than 15 ml/kg/min oxygen

consumption with cardiorespiratory limitation, or; cor pulmonale

or pulmonary hypertension, or; requires outpatient oxygen

therapy 100

FVC of 50- to 64-percent predicted, or; DLCO (SB) of 40- to

55-percent predicted, or; maximum exercise capacity of 15 to

no more than minimal symptoms such as occasional minor

hemoptysis or productive cough 50

Chronic pulmonary mycosis with minimal symptoms such as

occasional minor hemoptysis or productive cough 30

Healed and inactive mycotic lesions, asymptomatic 0

**Note**: Coccidioidomycosis has an incubation period up to 21 days, and
the disseminated phase is ordinarily manifest within six months of the
primary phase. However, there are instances of dissemination delayed up
to many years after the initial infection which may have been
unrecognized. Accordingly, when service connection is under
consideration in the absence of record or other evidence of the disease
in service, service in southwestern United States where the disease is
endemic and absence of prolonged residence in this locality before or
after service will be the deciding factor.
